Another Successful Project following the Bible’s Method of managing Sound.

Posted by jdbsound on May 2, 2022

Excellent Acoustics on the first day of worship and every day after that!

Most acoustics treatments applied to churches fail to improve congregational singing.  Yes, adding enough of any acoustical product to a worship space will change how the room sounds, but in most cases, the change is exchanging one set of acoustics problems for another set of problems.  As a result, there is no real improvement in the overall quality of worship. 

When using the Biblical method of treating the acoustics of a worship space, not only is there an improvement, congregational singing is significantly enhanced.  In most churches that upgraded their sound the Biblical way, the audience participation often goes from less than 30% of the congregation signing to over 70% of the congregation singing within a few weeks after the worship space is upgraded.  This realizes a church attendance from 5 to 25% within the first year and higher attendance for years to come.  This improvement in attendance comes from making the room friendlier to anyone with hearing issues, which affects from 8 to 25% of any population group.

Shantz Mennonite Church

Having any worship space enhanced with Biblical acoustics makes the room more accessible for everyone rather than just for younger people.  Here is an example of a brand new church, where during their first worship service, the song leader asked everyone to sing acapella.  Few churches begin with good sound on the first day and every following worship service.  Whether a new or existing church, bringing the sound performance level up to Biblical standards makes the performance of the worship space a room where people will want to worship in, rather than a place where people wonder if they can understand the whole message without playing it back later electronically. 

If you want to experience a great-sounding worship space, visit Shantz Mennonite Church in Baden, Ontario, Canada.  This is just the latest of the hundreds of churches that have had their sound managed according to what the Bible teaches.  Sound in a worship space managed any other way comes up short in meeting the needs of any congregation. 

Here are more images of the church.

Flow Chart of the House of Worship God Designed for the best Sound and Acoustics

Posted by jdbsound on November 4, 2021

The path to the best sound and acoustics for a church can be found in the Bible. Who knew! Here is a printable version of the House of Worship flowchart. There are a number of updates, improvements, and a bonus, the secret sauce recipe for church acoustics. All of it is based on the scriptures.

The flow chart is in two parts. The first part details the temple in terms of how every part of the building points to Jesus, Christians, and how the Holy Place was a template for the modern church. This section can also be used as a Bible study or study guide for anyone interested in Solomon’s Temple.

The second part does a deep dive on the sound and acoustics side of the temple and how that translates into meeting the needs of modern churches.

The house of Worship that God designed solves the one problem most churches have – poor congregational singing. Studying this method of sound management for churches solves the congregational singing issue, and it removes most of the limiting factors that affect all sound systems. It seems that there is a symbiotic relationship between good congregational singing and amplified sound that was unknown until a Biblical solution to church sound management was applied.

There are many churches that have very high quality and expensive sound systems that are performing well below their full potential and most church owners don’t have a clue of either how much better their sound system should be performing or are unaware of how much unmanaged acoustic or the wrong kind of acoustical treatment is limiting what their sound systems could really do.

The other thing that must be made clear, no sound system or electronic technology can affect congregational singing. The only effective method of bringing in good congregational signing into existing churches is by using the method found in the Bible. This method of managing church sound can be universally applied to all existing building shapes and designs, denominations, and all worship styles. Many pastors and church apologists often say that the scripture is sufficient in all things. Applying the Bible’s method to managing the acoustic of a church once again proves that such thinking is also applicable to the modern churches Christian around the worship own and use to worship God.

The file is large and can be printed into a 23-page document to be shared with others.

Passive verses Active Worship. Is there a difference?

Posted by jdbsound on October 8, 2021

Many people ask how the panels will look before hearing how they perform when it comes to managing the acoustic of a sanctuary for worship. Here is a short video compare two acoustic treatments. One system comes from a non Biblical solution that partially works and very expensive. The other system comes from the Bible. It provide the proper acoustical conditions for worship every time and at a fraction of the cost. Our experience shows that most church members change their opinions on aesthetics when the acoustical fix does a great job at fixing the room.

Congregation members of most churches do agree with one idea. It seems that if the acoustic system fails at improving congregational singing, the panels on the wall have to look good as wall furniture. If the acoustic treatment improves all parts of worship, especially congregational singing, concerns about how the panels look melts away. The aesthetic issues disappear.

The half round diffuser systems are also passive noise cancellers. If you have a noisy HVAC system, they can reduce noise up to 20dB at no extra cost without over dampening or compromising the worship space acoustics.

If you have any questions or comments or want other subjects discusses, please post them below.

Phase Gradient Diffusers vs. Tube Radiators. Which gets better results. Church Acoustics

Passive worship is when people feel alone during congregational singing. Feeling alone prepares people for hearing a feel good message, whether it is the prosperity or self help gospel.

Active worship is when more that 60% of the congregation is actively singing all the time, and for some, sing the harmonies in the hymns. When there is active singing, it helps to unite people to hear the full Gospel message regardless of how strongly that message is preached. Active worship often leads to a stronger church and people making long term relationships.

The acoustical condition of a worship space is a very accurate measuring tool to determine the type of worship any church practices. A good sounding worship space supports congregational singing and does a better job at supporting amplified speech with less sound equipment.

An under-performing worship space not only makes a room full of people feel like they are all alone, but it takes 3 to 4 time the audio equipment to get decent speech quality and since less that 60 to 75% of the congregation is not singing, the excessive sound system is also used to entertain the congregation with worship teams and performance singers. What better way to end a long session of feel good music to cap it off with a feel good message. Here is an article that explains this more.

Church Acoustics is really simple.

Posted by jdbsound on September 24, 2021

At least according to the Bible.

Church sound is in a mess.  Many Christians are being denied true Biblical worship and they don’t even know it. There is an easy way to fix it, and the solution comes from the Bible. The following article covers many details on how the Church community has gotten itself into this mess and a proven solution from the Bible that works 100% of the time is shared in detail.

The article is 15 pages and is about a 30 minute read. If you want to just get to the recipe for the Bible’s solutions to ideal church acoustics, where you can upgrade any existing worship space, go to page 11. However, if you want to know what direction your church is going, and to understand how acoustics is changing church worship into church entertainment, there is an opportunity to reverse the decline, and to restore the kind of worship the bible describes from cover to cover.

Is the church community ready for the return to partial or fully attended worship?

Posted by jdbsound on September 8, 2021

These days, many Christians have been getting their Bible and Gospel teaching through the internet during the long-term pandemic lockdown because of the Covid-19 virus.  Hearing worship services or sermons online may not be the best way to experience church, but it does have its benefits.  For one thing, the quality of sound from a computer or TV will be surprising much better than the quality of the current condition of the live sound in most worship spaces. Should any words or phrases be misunderstood at home, a person can pause the video and repeat the segments they had trouble understanding.  A person can adjust the volume on demand to make spoken words as clear as possible.  After 18 months of hearing sound from a TV or digital device, how will people react when they return to church and find the sound much lower in quality than they are now used to at home?  Do they stay or leave?

It takes time to get people used to listening to the sub-quality amplified sound found in most churches.  Will people want to go through the learning processes of having to adjust their hearing again?  Will people want to stay home to hear worship where the sound is much better?  Many churches have made the best of a bad situation with this Covid-19 pandemic and imposed restrictions.  When people return to live worship, will they prefer to worship at church or the televised worship?

Shouldn’t it be that the live worship is of higher quality than the broadcasted worship?  Is it possible to get the live worship to be of better quality than the broadcasted or pre-recorded message without compromising anything?  Yes, it is possible.  The good news is that in 90% of the cases, the sound system does not have to be upgraded or other expensive changes.  What anyone can do is follow what the Bible teaches about large room acoustics.  The Bible has a clear and straightforward plan that can raise the quality of sound of any worship space and often for less than the cost of a wireless microphone system or two. 

Imagine for a moment of a church seating 200-350 people and spending less than $1,000.00 to make the sound in the worship space of equal or better quality than hearing worship at home. What about churches seating 350 to 500 seating? Would it be worth investing $2,000.00 to get better sound?  How about churches seating from 500 to 800 people? Would investing $3,500.00 be a reasonable price to pay to offer church members sound quality that makes coming to church a great experience?  How about investing less than $5,000.00 for a 1200 seat church?  How about investing $6,500 for a 3000 seat church, creating a sound quality as good or better than what people hear on the internet?

The Bible has always offered higher-quality sound in worship spaces. However, until now, people have been looking outside of the Christian community for answers.  The Bible offers a solution to transform any worship space to have superior congregational singing for hearing clear speech, and it draws out the highest level of sound system performance for speech and music regardless of the quality of the equipment.

If there is a concern about how people will react when they return to the sanctuary for worship, it is never too late to make such an upgrade.  To learn more about upgrading the acoustics of a church affordably by following the Biblical teaching of the scriptures, contact JdB Sound Acoustics today for assistance.

Why post free information about church sound and acoustics on the internet?

Posted by jdbsound on August 6, 2021

The Bible is sufficient in all things.  That includes worship space design, acoustics, and sound – including amplified sound.  While it is true that amplified sound did not exist until 100 years ago, by following the design details in the Bible, the result is having the fullest performance out of any properly designed and installed sound system and hardware in God’s house.  The moment the Bible’s teaching is ignored about sanctuary design and acoustics, it limit the performance of every piece of electronics installed. It limits congregational singing, and, in many cases, speech becomes compromised enough that the sound system becomes a barrier between the minister and the audience, denying some people the chance of understanding the message of the Gospel of Jesus Christ or the teaching the minister is trying to convey.

Every year millions of Bibles are printed and given away.  With the internet, the Bible is free and accessible to everyone around the world.  As said earlier, everything we need to know in building a house of worship that fully supports Christian Worship in every way is in the Bible.  The problem has been that while there have been examples of people who tried to copy Solomon’s Temple in the past, they failed because no one understood the real purpose of the palm tree carvings on all the walls and doors in this holy place.  If they had known its actual function, then it could be possible that both Jewish Synagogues and Christian worship spaces would all be looking very similar on the inside. 

For years people have thought of the carvings as decorative while others have given these shapes spiritual meanings.  While spiritual meanings can be attributed to the Cherubs and open flowers, the palm tree is the most out-of-place item within the temple.  Many Bible scholars and historians state that everything in the Bible has a purpose.  Then what was the purpose of the carvings of palm trees?

Furthermore, how did the details of the palm tree carving survive 3500 years in Jewish and Bible Scriptures?  Knowing a little about how the Bible was compiled, such detail could have been easily left out and forgotten unless there was a purpose for it that God wanted us to discover.  In 1994, I stumbled across the purpose of the palm tree carvings.  This led to a universal way to fix existing Christian worship spaces and Synagogues.  This method of improving churches is the most effective system of fixing worship spaces, and it is a very cheap solution as well.  Once the purpose of the palm trees and Cherubs were decoded, it became the key to unlocking how Solomon’s Temple was supposed to function.  I started looking under the gold and discovered that the temple is a template of every aspect of modern worship space design that all churches need, and it has been in the Bible all along.

I cannot speak to the reason it took us so long to figure all of this out.  I know that if I were to keep this information private or patented it or licensed it, it would deny more people from hearing the Gospel within worship spaces, and I do not want to be responsible for that.  It would be wrong for anyone to keep such information a secret to the Christian Church community.  Three years later, and after 30 church installs of this acoustical system, I began sharing my knowledge on the internet in 1997 as a DIY system any one church can do on their own.  I tested the worship spaces to document and confirm the effectiveness of this method of finishing the walls of existing sanctuaries is. 

The struggle of hearing and congregational singing within a confined space has been with us since Christianity began.  In 313, after Emperor Constantine became a follower of Christ and ended government persecution of believers, Christians took over pagan temples and began worshiping in them. Since then, Christians have turned to everyone else in designing worship spaces and have allowed the secular world to dominate church Architecture.  From then to the present, Christians have been worshiping in buildings that can never meet all of their worship needs unless that house of worship follows what the Bible teaches.

Today, because of radio and TV broadcasts, mass media, and the internet, the number of false teachers and wolves in sheep’s clothing are so abundant and clever that it is harder to tell who is teaching Christ and who is teaching a false version of Jesus.  These false teachers have become so good that they have formed congregations of people who are followers of a false Gospel and build large mega rooms, and claim that their buildings are houses of God.  There are thousands of congregations following false teachers around the world.  It is so bad that it is almost impossible to tell the false teachers apart from the faithful ministers for Christ.  Both in broadcasting and internet media, these false churches are now dominating the screens of what non-Christians are exposed to the first time they see this type of religion.  This form of religion preys on the poor, the weak, the un-education, and all classes of those looking for a shortcut to wealth and prosperity to satisfy their hidden sin of greed.

The one thing that I do know is that false churches don’t want to fix their acoustics as detailed in the Bible.  They want the kind of acoustics and sound systems that are as good or better than what you will find in Las Vegas or any other secular performance space.  They don’t even want their worship spaces to be as good as concert halls.  They want a place where you can put on a show, a place where it is easy to manipulate people’s feelings to be more receptive to false teaching.  Get people all excited for a half hour or longer, and you can get them to do and believe almost anything.  Then, add in lights that change colors, fog machines, huge video walls, and abstract backgrounds, and what doesn’t get you emotionally hooked with sound, they add “eye candy” into the mix to secure your loyalty to them.  These false churches put on a fantastic musical show. 

They don’t care whether you sing or not, as long as they can get you addicted to being in mood and be receptive to hearing false messages of spiritualized positive thinking.  Positive messages are always about focusing on self-improvement.  Self-improvement is code for placing yourself on the throne of your heart above God.  People are being duped into believing everything from being able to save yourself to deserving to be as wealthy as the false teacher they are following.  Not only do these false teachers put on a spectacular, addictive musical show, but they put on a verbal presentation that is as good or better than most professional self-help motivational speakers who also live like the rich and famous.

In a way, these false teachers have convinced millions of people into believing that their version of religion is better than winning the lottery.  Give us your money, and God will make you rich!  They turned tithing into the concept of buying lottery tickets as a group celebration.  The tickets have no numbers, the winner is always the leader, and the losers are all those people who don’t have a clue that there is a life after death.  Live for the moment, that tithe will pay out any day now!  People who are in this trap, do they know they sold their souls?  Nowhere in the Bible does it say such teaching or imply such promises.  One of the greatest fears these false teachers have is a worship space that performs as well as Solomon’s Temple.  Why?

When a worship space follows the Bible’s design for a house of God, the Christian will not need the show to experience authentic congregational singing and true Biblical worship.  They won’t need the manipulative entertainment performance to get people into a hyper mood.  The congregation will hear and understand the words in the songs they sing and get a blessing without being manipulated.  Singing chouses gets boring fast when somebody can’t maneuver you into a trance.  When you can get a blessing from singing hymns as a congregation, you don’t need to be entertained with a 3-ring circus.  True hymns include the Gospel message.  Most new songs that are sung as worship songs these days have no gospel message in them whatsoever. Saying Jesus 30 times doesn’t make it spiritual but telling people Jesus died for your sins just once can open a persons’ heart.  A true house of worship exposes false music entertainment performed in churches.  Once the false music doesn’t have a hold on the congregation, it becomes almost impossible for false teaching to follow.

Spiritual warfare comes in many forms, and one of them is by having houses of worship that perform better as an entertainment center.  It is in those places where a corrupted gospel can get a foothold into the church community.  Fix the houses of worship we have and design new ones as God always intended for us to have, and you can reduce the number of false teachers significantly. 

There is enough information here for you to figure out how to fix your church and get most of it correct.  By making this information freely accessible for existing churches, where they are determined to preach the Gospel, they can affordably upgrade their churches and add another roadblock to false teaching entering the church. Already hundreds of churches have taken the leap of faith, and all of them have seen and experienced dramatic change.  Trust the Bible, and you will expose your church to True Christian Worship, and you will join the other churches that are growing because of the Gospel, not in spite of the Gospel.

This battle cannot be fought alone.  With your help, pass this information onto other Christians and churches, we can put a dent in slowing down or stopping the ever-expanding plague of false churches around the world.  It becomes easier to preach Jesus and the full Gospel message the right way in large spaces when existing churches are transformed into acoustically friendly worship spaces.  Good acoustics is a big help in making God’s Word that much more effective. 

Pass this on.  It only takes a spark to make a difference.

Bible Questions the Church Community is not answering.

Posted by jdbsound on July 31, 2021

Here are 27 questions for Biblical scholars, pastors, and experts to answer about Solomon’s Temple. Please ask your pastor and church leaders and see if they understand the purpose of these questions.

  1. There are carvings of palm trees on all the walls and doors in the temple.  Were these decorative, spiritual symbols, or was there a practical purpose for them?  1 Kings 6:29
  2. Why were there also carvings of Cherubs and open flowers?
  3. What was the purpose of these carvings on the doors to the Sanctuary and Holy of Holies?
  4. Was there any other purpose for the veil on the Sanctuary wall, in front of the entrance to the Holy of Holies?
  5. Is the height of the Holy Place or Sanctuary the ideal height for congregational singing?
  6. Are the floor dimensions of 60L x 30W feet or 2 to 1 ratio ideal for teaching and hearing?
  7. Do these dimensions offer the best conditions for hearing clear speech?
  8. Are the upper windows part of a method of controlling temperatures in the temple?
  9. What was the purpose of the gold on the floors of both the Holy of Holies and the Holy Place?
  10. What was the purpose of the gold on the side walls?
  11. Why were the walls and floor covered in gold, considering that no one other than the Levite priests was ever allowed to see the gold or to enter the temple?
  12. Why was cedar used under the gold on the walls?
  13. Why was Fir or Juniper wood used under the gold on the floors?
  14. Did the wood offer any thermal stability in the main building, considering that people cooked and slept in the chambers around the temple?
  15. Why was pure olive oil used for the oil lamps in the Holy Place / Sanctuary?
  16. Are the olive oil lamps a statement or example of being environmentally responsible?
  17. How much illumination did the 10 lampstands with 7 oil lamps provide?
  18. Would that be enough illumination to read scriptures before and after sunset?
  19. Would the design of the building using the outer rooms where each floor and roof sat on a ledge for each of the 3 levels, create an earthquake-resistant building?
  20. The total floor space of the temple is 9,156 sq feet.  The Sanctuary is 1800 sq feet.  That creates a space of 7,356 sq feet for a prayer room and storage rooms, which is about a 5 to 1 ratio for supportive space to the Sanctuary.  Why are modern churches always complaining of not having enough space?  Would following the Bible in this matter solve that problem?
  21. In Numbers 7:89, “Now when Moses went into the tent of meeting to speak with Him, he heard the voice speaking to him from above the mercy seat that was on the ark of the testimony, from between the two cherubim, so He spoke to him.”  Did this account of what happened to Moses set a precedence for how God would communicate to the Israelites after Moses was gone?
  22. If it does, consider this: The Holy of Holies was a cube, 30 x 30 x 30.  Such a room covered in gold would sound awful.  Conversation beyond 3 feet would be impossible if there was no acoustical treatment.  Would there have been the need for acoustical treatment in the Holy of Holies as the priest could not get any closer than about 12 feet from the Ark of the Covenant?
  23. Would the design of the temple be soundproof enough to be neighborhood-friendly by keeping worship noise in and city and traffic noise out?
  24. If John 1:3 is true, “All things came into being through Him, and apart from Him nothing came into being that has come into being.”, and King David said in 1 Chronicles 28:19, to Solomon that the hand of God was upon him in the designing of these patterns, then who is the true designer of Solomon’s Temple?
  25. When Jesus said about the laws and the prophets in Matthew 5:17 “I did not come to abolish but to fulfill.”  Does that include anything that Jesus designed in the Old Testament? Does this make Jesus Lord of the Worship Space? (how do you fulfill Solomon’s Temple in the New Testament?)
  26. Why don’t modern churches follow the Bible’s example of what seems to be the perfect worship space?
  27. Does acoustics affect how modern churches worship today?

Bible experts on Solomon’s Temple or Biblical Historians seem mute on answering these questions.  Why?  These are questions some Christians think about but never bother asking Biblical academia as they know they will not get any objective answers.  Also, some experts have a way of making you feel like you just asked a dumb or foolish question.  It is time for Christians to ask their pastors and church leaders to do the research for answers to these questions.  These are not spiritual questions, but knowing the answer could be a big help with solving many of the problems modern congregations have with their church buildings today.

Interestingly enough, there have been many times where from the pulpit, many ministers and clergy will say that everything we need as Christians come from God or something similar.  Why is it then that when it comes to church design, which includes sound and acoustics, we look elsewhere for the answers rather than use the example of what the Bible teaches?  Isn’t what Jesus designed good enough for us today?

If you know the answers to any of these questions, post your comments below.

The Average Church Buys Ten Sound Systems

Posted by jdbsound on July 15, 2021

Do churches really buy that many sound systems?

The first sound system

The first sound system is the cheapest system the church can afford and is installed without much knowledge or research about system design, by someone with good intentions. 

It does amplify sound, and everyone adjusts their hearing and puts up with it.  Every time the system is turned on, it sounds different.  This sound system lasts only until the minister threatens to leave, when church members do leave, or enough people complain about it.

The second sound system

The second sound system is by a church member, or a friend of a church member, or a person, who does church sound on the side or as an extension of their secular business.  The new sound system is better behaved but, in the end, the overall performance is only slightly better that the previous system.  The minister is annoyed by people asking him to repeat or explain parts of the sermon almost every week.  The person or company installing this sound system are under the notion that at the end of the project, they will have a modest profit. Did anyone see a Profit! Oh! What a novel idea! 

The third sound system

The third sound system is a sound system designed and installed by a professional, meeting most of the goals promised in a verbal agreement.  While some parts of the sound system are performing well, other issues become more noticeable.  Yes, there is less audio feedback heard, but speech clarity for people over 40 has not improved.  Amplified music sounds mushy.  The minister’s confidence takes a hit every time people talk to him after the service or through the week, asking questions as if he is not preaching the Gospel properly, when it was the sound in the room that changed the words that left his mouth and arrived to the listeners as being something else.  Some people returned because the sound was more stable, not because it is much better, and for others, it is more likely they miss their friends.

A written agreement is never offered or requested because we all know the myth and lie, that the outcome is too unpredictable and rarely lives up to expectations.  Often this sound system is in whole or in part paid for from a single donation or is bequeathed from a persons will.  The professional thanks the churches he helps for upgrading his car every few months.

The fourth sound system

The fourth sound system is designed and installed by another professional promising to do better.  In making some parts of the sound system better, it came at a compromise of something else regardless of the cost.  The church buys additional hardware for the system from someone else and it does provide some marginal improvements, but not enough to satisfy most of the church members.  The designer had suggested for acoustical improvements but downplays it so that the acoustics would not impact the sound system profits.  People with hearing aids that have the “T” switch like the loop system but even in the hearing aids, real sound clarity is not there, even with the high quality digital technology used to make a loop system work so much better.  While these people are not straining to hear because of loudness, understanding the message does come into question.

Another mythical illusion that is often perpetuated, is that there is more profit in audio hardware than in supplying acoustical treatments and proper acoustics fixes are too expensive for the average church to afford.  The professional thanks the church for the new motor home. 

The fifth sound system

The fifth sound system is installed by a well-known professional who also expresses a warning that the acoustics must be fixed too.  After the installation is completed and after the honeymoon phase of the upgrade has passed, you realize that things that have improved did get better, but other problems showed up, limiting the sound system’s overall performance as being no better.  You call him to come back, he offers you more gear, but you cannot afford it. 

Many people say they like hearing the MP3 playback of the message in their car, on their computer, or Bluetooth, and most of them quietly wish they could have understood the message while at church, so as to being able to ask the minister meaningful questions at the end of the service to expand their understanding of the Gospel.  Church elders notice a high turnover in church attendance. They attribute the turnover to social and economic reasons, certainly not because of sound.

Inside of all the fancy professional paperwork, there was supposed to be a professionally written performance agreement, which was never included, so the church has no recourse.  The cycle of stepping two steps forward is met with surprise when everyone finally realizes that they also took an equal two steps back.  The professional keeps your money regardless of your choices and swims victory laps in his new family swimming pool.

The sixth sound system

The sixth sound system is installed with great promise by a high-end professional with the same warning that the acoustics should be addressed.  The proposal included an acoustical design that came from a person who is a professional at noise management, and has never designed a successful performing acoustical space in any of those type of projects.  The church ignores doing the acoustics, banking on the new “state-of-the-art” devises that are filled with promises of improvements to make the sound problems go away. 

In silence, the church leaders accept another expensive system upgrade that shows just a minor change that hardly justifies the cost.  There was hope that the congregation would be more involved with singing, but they are just as passive as before.

The high-end professional takes your money without hesitation so he can have bragging rights to sell to other churches.  These professionals know that the majority of churches do not talk to each other or check references.  They also know that most churches are too stubborn to get their acoustics fixed first.  The professional upgrades his home theatre to schmooze and impress his secular clients who are harder to sell products and services to, because they have specific performance goals written into their contracts that they will not compromise on. 

The seventh sound system

The seventh sound system looks impressive, and it also includes a different acoustical design.  The professional suggests that the bigger and “better” new sound system would be a great sales gimmick to attract more people from the church across the street.  More people do come, but because the Church board, did not implement the acoustic plan, congregational singing languishes, and more hardware is purchased to do entertainment style worship, leading most of the people into getting engaged in the show.  The rock concert quality sound system, the video walls, motorized lights, smoke machines, are all adding to the entertainment elements that distract people from the subpar sound quality.  The professional now travels first class.

The eighth sound system

The eighth-sound system the professional designs is used as a gimmick along with multi-media to compete with other online ministries.  Additional digital technology is used to mask the real sound of the church from the online service and to broadcast publicly. The equipment does an excellent job in preventing people from hearing echoes and the poor-quality reverberation of those who have attended church, have learned to put up with.  For those who attend regularly, they like the weekly show.  The right acoustical treatment would have been cheaper, but the enslavement of technology blinds everyone from seeing the bigger picture.  The church continues down the path of substituting worship with entertainment – but still calling it worship because they include words like Jesus, Holy Spirit and God in some of the songs.  After all, it is all about Him.  We can get saved later.  Right!

After getting a contract and deposit, the professional, who used an expensive rental car during earlier visits, shows up in a new luxury car, demonstrating that high end sound systems are needed in every church, regardless of whether they make any meaningful improvements.

The ninth sound system

The ninth sound system the professional designs is to keep the church growth momentum moving forward to attract more people from the other side of town.  Again, acoustics is ignored.  Since most of the other churches have subpar acoustics, most people attend the church with the best music show, the best motivational preacher, the best coffee, the best free food, the shortest sermons, or all the above. Such churches get people addicted to the drug like effect when dopamine and endorphins are released after following a specific ritualistic, high energy program.  Who can pass up that kind of drug and alcohol free high every week? 

Scientists call dopamine and endorphins the Happy Drugs the body naturally releases when stimulated.  A galvanizing, well planned choreographed series of songs, music, visuals, and storytelling events trigger the natural drugs in the brain.  Many people are hooked to this type of worship.  Whenever the show becomes too routine and it does not have enough stimulation, many will look for other churches to get the same buzz.  When that stimulation isn’t enough, then they go back to the first church and start over again.  Biblical teaching becomes secondary or nonexistent and any teaching from a Bible is focus on ways to keep people stimulated by focusing most of their attention on themselves. 

Who knew that sanctuary acoustics could lead to secularizing the church worship into worship entertainment?  Many churches, look and sound like a business rather than a place where Christians come to show their love of God through a holy time of gathering of the faithful – and not the addicted?  Some churches have bought different versions of the ninth sound system purely to attract those who thrive on that kind of stimulation which is a cheap way to get rich in a religious business.  Oh, didn’t you know!  Most people with a higher income greatly support churches that make them feel good.  Being saved or born again, is assumed or skipped over if you give a lot and the message makes you feel better.  That is no different than those high priced motivational speakers living very wealthy lives entertaining people with their secular version of the health, wealth and the prosperity gospel.

The professional tells his neighbor how another church paid for another addition to his house.  If you want to soar with eagles you have to be an eagle.  In case you didn’t know, eagles are classed as scavenger birds.

The tenth sound system

The tenth sound system is designed by an expert.  This is the final new sound system most of us never hear about.  It is a sound system that will never have to be redesigned again.  All that is required in the future is that as equipment ages, you only need to replace what is broken or upgrade the technology as more capabilities become available. 

This sound system is designed the same as the 3rd sound system following the upgraded acoustics designed by someone who does church acoustics and sound systems exclusively and gives a written description of how the worship space will perform after the upgrade.  Even though his professionalism is lacking, everyone is thrilled that congregational singing was finally fixed since the church opened at no added cost.  The acoustic upgrade, which costs a fraction of any of the other sound systems allows this older sound system design to outperform all the other six previous sound systems by 400 to 2500%. (Audio improvements follow a logarithmic scale.)  If your church is past its third sound system design or upgrade, stop, save your money, and fix the room.  The room is essentially screaming that it needs to be fixed and the sound system is always amplifying the problems.

There are a lot of sound contractors who will keep designing, selling, and installing you a newer sound system so they can buy a newer cottage, a bigger home or take another cruise ship vacation this month. The expert looks into the full church and prays that another soul hears the Gospel message and starts living a life with Christ, than seeking religion.

The facts

The fact is, not many churches will really buy 10 sound systems.  Few churches will start with the tenth sound system.  The majority of churches skip steps, but the outcomes are no different.  Many churches start with the first sound system while many newer and wealthier churches start with the 3rd or 4th system.  Other churches go from the 4th, to 7th, or 8th system.  Some churches are on the 3rd or 4th version or the 9th system.  The shortfall of these worship spaces are all predictable by the mere fact that any room that doesn’t have any acoustical treatment or the right method of managing church acoustics, means  the results are always the same.

Equipment

Churches that are on system 3 through 9, often have individuals who are gadget and technology driven.  To some of them, fixing the acoustics is like putting the brakes on technology.  If anything, visit any church out there that has upgraded their sound system in the last 5 years and you will find lots of perfectly good hardware that was deemed useless because it didn’t live up to its promised performance.  The truth is, all of that hardware that is still working or repairable would have never been bought in the first place had the acoustics been ideal.  With good acoustics, the tendency is to buy higher quality technology less often because you know it is going to work the first time and every day after that as the manufacturer designed it.  Every piece of audio hardware is limited by the acoustics of the room it is used in.  That is a hidden secret every equipment manufacturer knows about and intentionally leaves out of their manuals.

If you ask any audio manufacturer these days, many will admit that 50 to 60% of their equipment ends up in churches.  Yet after 70 years of churches with sound systems, in all of that time, the quality of worship hasn’t really improved.  The only change is that in more and more churches the worship is switching from active participation in the pews and seating, to passive worship.  That really isn’t worship – that is being entertained.  That is like being addicted to feel good messages and a focus on what you get out of worship rather than worshiping because you have a true love for God.

What should worship look like, Matthew 22:37-39 He said to him, “ ‘You shall love the lord your god with all your heart, and with all your soul, and with all your mind.’ “This is the great and foremost commandment. “The second is like unto it, ‘you shall love your neighbor as yourself.’ 

When you are at church, during worship, do people sing and pay attention to the sermon with the focused attention of someone loving God with all their heart, mind and soul, or does it look like people having a good time, swaying to the music, sipping coffee during the sermon, remembering the jokes and the story at the beginning that often has little to do with the short message? 

After working with churches for a long time, these are some of the stories some churches have shared on their journey to getting the performance from their worship space and sound system their congregation deserved.  The ongoing myth that eventually audio technology can replace or put off the need to complete or fix the acoustics of a church is one of the most expensive decisions a church can make.  For some churches, the repeated cycle of redesigning sound systems to reach that elusive goal of perfect sound every few years, costs more than replacing a parking lot, a roof,  more storage, employment for a second pastor or church staff, and so much more.  Technology improvements comes with the illusion that it has the power to defy the laws of physics when it comes to church sound systems. 

A sound system can only perform as well as the room allows it.  You do not have to take my word for it.  Look at any concert hall or performance space that is profitable and it will have acoustical planning, panels or features that help to turn any performance into a memorable event.  The same applies to recording studios.  The better the acoustics, the less time it takes to complete a project, the lower the cost to the customer.  The quick results and lower costs lead to a higher rate of returning customers for future projects.  Recording studios and concert halls depend on repeat business and the single most common elements they have are acoustics.  Why would this model for sound excellence be any different in a church?

What is the difference between an expert and a professional? 

The church sound professional is the knowledgeable salesman with business degrees and higher education, often in unrelated fields for his business or company.  While their company does a lot of churches, church work is not exclusive and is no better than anyone else’s results.  Everything that they do is profit driven.  The professional knows how to say what the customer wants to hear, manipulating the customer into believing they are the best.  The professional shows an extreme level of patience, well-rehearsed business etiquette, confidence, quick with the paperwork, and makes the promise that whatever you ask for, they have the talent to do it.  Professionals count on repeat customers who remember their professionalism that masks their recollection on the unimproved results. 

The church sound expert is the person who works exclusively on churches.  He knows how to accurately diagnose the problems, and is compelled to tell you the truth, whether you like to hear it or not.  He believes that the more informed the church leaders are, the more likely the church will make the right decisions that will save the church thousands of dollars in the future.  He can precisely predict the results before anything is done and rarely makes mistakes.  He can back up the results from past experiences.  The expert will be honest and care more about getting you the right solution that will work the first time, at the expense of any illusion of being a fancy, smooth talking professional.  The expert is often not profit oriented, he cares more about your reputation within the church community, by getting results that count.  He often gets referrals or is asked to fix other rooms in the same church, and never gets a repeat customer.  If the expert must go back and fix the room again, he is not an expert. He is a “professional expert,” you know, the jack of all trades, passing himself off as an expert.

Does sound quality in a Worship Space –

Posted by jdbsound on June 22, 2021

  • Affect church attendance?
  • Affects church finances?
  • Affects church health?
  • Affects a church’s reputation within a local community?
  • Affects how people respond to the Gospel message?
  • Affects what a minister preaches the Gospel?
  • Affects how a minister preaches?
  • Affects people emotionally?

Myths vs Facts: 

According to various hearing organizations such as the American or Canadian Hearing Societies and other health organizations, 8 to 25% of people will have hearing loss or impairment within any community. For some people, the hearing loss is in one ear or both ears. For other people, using a hearing aid does make up the difference so those people can interact socially with others without needing to use sign language. The bottom line is, if a person can have a normal conversation in a living room but has trouble hearing and being engaged in conversations in larger rooms, these people are less likely to attend a church with less-than-ideal acoustics and amplified sound. Hearing loss, the invisible disability, does make social gatherings awkward for many. Numerous people with hearing loss resort to the practice of self-isolation from social events, including weekly worship services. Sound does have an impact on church attendance for those who have any kind of loss or impairment.

Good acoustics and sound system design in a church make the worship space much more accessible and appealing for those with hearing loss within any community. That is why churches that follow the Bible, when it comes to worship space acoustics, experienced a consistent and sustained 10% attendance increase on average 6 to 18 months after upgrading, while churches that just upgrade their sound system and not the acoustics realize a short-term increase of 5% and 2% over long-term follow-ups. Churches that upgraded both the acoustics and sound system saw no significant attendance changes when compared to churches that just upgraded the acoustics. (However, some churches did reinstalling the existing speaker system to take advantage of the better acoustical conditions and expand the performance of the sound system.)

These facts have been consistent with churches where the pastor, church leadership, and local economies had not changed from 3 years before to 5 years after upgrading the acoustics. The conclusion is, no matter how good or popular your pastor is as a preacher and leader, if the acoustics and sound system are not up to Biblical standards, there are many people who are being excluded. Depending on your point of view, some people see this as a denial of service.

Another thing to consider is that an attendance change of 10% also adds up to a 10 – 15% annual increase in tithes and offerings. For a typical 400 seat church, that could represent an income difference of $208,000.00 over ten years or enough money to replace a church roof.

(Fact: Most churches will sell parts of their property, including their parking lot, to pay for building repairs such as roof replacement.)

Church Size400 seating
Before average weekly church attendance230 people
People returning to attending because of hearing improvements10% or 23 people
Average giving per person (Health Research Funding Org. May 2020)$17.00
Weekly giving increases$390.00
Monthly increases$1,564.00
Annual increases$20,280.00
Over 10 years$208,200.00
Stats are provided from client follow-ups of 5, 10, and 20 years which followed the Biblical method of managing church sound.  The sample size is from 130 of the 400 churches that upgraded their acoustics between 1994-2019.


Not knowing if the acoustics of your church are up to Biblical standards could mean that your church is denying people from attending your church more frequently or from ever returning.

While there are many personal and spiritual reasons for people not attending a particular church, our records show that good acoustics combined with a quality designed and adjusted amplifying sound system constantly translates into higher attendance and tithing. For some churches, the better-quality sound translated into higher giving from people who did not have a hearing issue which was unexpected in our research. These were people who responded to a questionnaire where one of the questions asked, if they noticed the higher quality of sound and whether it affected their tithing. The most consistent response was that when the church board invested in its members by making the worship experience better with quality acoustics, then they felt it was worth investing in a church that took care of its own first, and out of the excess, they could better support others including missions. Church sound is not just an emotional experience; it is a physical experience that directly impacts church attendance and finances.

The Biblical standard for church sound comes from the Bible and specifically in the Story of Solomon’s Temple. In following the story literally, we find that what God designed through the hand of King David is a house of worship that makes it possible for modern sound systems to perform at their highest levels. This makes the room compatible for people with all ranges of hearing loss, and it provides ideal sightlines for people who start to learn lip-reading as their hearing declines with age. Solomon’s Temple is also compatible with ADA (access for Disabilities Act) and other similar laws around the world as the Temple had no steps in the sanctuary, making the worship space wheelchair friendly, even before wheelchairs were invented. Solomon’s Temple doesn’t just set the standard for church sound; it sets the standard for all aspects of church worship and building planning.

You should get your worship space assessed and know it’s acoustical score. If there is room for improvement, have a plan in place when your church can afford to upgrade. On the other hand, some churches have upgraded their acoustics as a last-ditch effort to remain relevant in a local community. All of the churches that made such a desperate move are still open, healthy and have expanded their status in their local community. The knowledge we now know about Solomon’s Temple can benefit your church today.

Then there is the issue of quality versus quantity or loudness. Do people want their sound louder or of better quality? Research suggests that most people choose quality over quantity, hands down. This is especially true for people with hearing problems. While those with hearing loss and using aids to help them hear, a loud sound with distortion renders their hearing aid less capable of help than a clean sound at a lower volume.

Sound systems that have too much distortion at any level are a turn-off because distortion can become painful as the sound levels increase at certain frequencies. Many expensive high-end sound systems are distorting long before reaching their maximum loudness levels. Young people who hear distortion tolerate it better than people over 25 years of age. They often have the mindset that if you turn up the sound system loud enough, the distortion goes away. What they are really doing is desensitizing their ears while damaging their equipment at the same time. Ears have a limited natural way to protect themselves by tightening muscles around the ear canal and drum for short-term excessive noises. For older people, these muscles are not as effective, and distortion becomes intolerable, assaulting the ears at lower volume levels as people age. On the other hand, when the sound quality is high and free of distortion, people of all ages enjoy the louder amplified music, considering that an unamplified congregation can sing over 100dB in a good room without complaints.

The quality of the acoustics, combined with a professionally designed sound system, does impact a church in many ways other than just attendance, tithes and offerings. That impact of sound quality can affect church attendance as little as 8% and some churches up to 18%, and that is just by attending to the physical needs of people. Unfortunately, we have no way of measuring how sound affects people emotionally and spiritually and whether that influences attendance. On the other hand, many movie theatres have upgraded their seating, installed higher-quality speaker systems, add substantial amounts of sound-deadening materials, and other details to enhance the movie viewing experience. Judging from the higher ticket prices people are willing to pay, there is little doubt of an emotional experience tied directly to sound quality.

The secular community has tested how sound affects people numerous times. By simply changing the quality of the sound, it affected how people judge the quality of the picture they saw on the screen. In one well-known test, two identical theaters were made to look the same in every detail. The projectors were the same as well as the popcorn and other items people do when watching a movie. While both theaters had carpeted floors and padded seating, one theatre had very visible acoustical panels and hardware on the walls and ceiling, the other theatre had fake panels that had no acoustical properties but looked identical. After having two groups of people listened to the same three movies over three days in both theatres, the majority of the listeners judged the theatre with the proper acoustical treatment to have a better picture and they remember much more details of the movies. Additionally, some thought the seating was more comfortable, the popcorn and drinks tasted better. Some also asked to see some of the movies again in the theatre where they found the seating more comfortable. As a caveat, the sound in the theatre without the acoustical treatment could not perform as loud, even though both sound systems were properly equalized, so the sound levels were set to a lower volume. The acoustically treated room with bass traps was able to perform to lower frequencies without any distortion which augmented the sound quality. This is a clear example of how sound quality affects people emotionally in a big way.

Finally, can the number of people responding to altar calls, faith healings, being slain in the spirit, speaking in tongues, and experiencing holy laughter be attributed to sound quality? For churches seating less than 400 people, that depends. Churches this size or smaller should have good enough acoustics without a sound system if the worship space meets the Bible’s acoustical standard. When the room cannot support quality sound acoustically, the church will resort to using sound systems to make up for the room’s failure to perform. At best, a typical professionally designed and installed sound system can raise the performance by a mere 10 to 15% of the room’s potential performance. When the room is acoustically upgraded, the room performance often improves 50 to 60%. In a bad room, at best, 1 or 2% of the people will respond to a worship service event. In a good room, you can add another 2 to 3% response to such church activities. Sound quality, along with uniformed sound coverage, will impact more people. Whether this translates into adding more people to the church, that is up to the church leadership and how supportive they are in helping people in understanding what just happened.

For larger churches, the sound system is very much part of the worship service all the time, and without the sound system, large churches cannot have worship, let alone get the responses that they may have. The larger the room, the more critical the acoustical management of the space becomes. In larger churches, sound quality has a larger impact on people responding to church events. The responses double between good and bad rooms.

When people like Billy Graham evangelized in outdoor stadiums, the sound was often fairly good everywhere because there were no surrounding room surfaces creating interfering reflections. Nothing was getting in the way of the spoken words. Even the echoes heard were not a problem because those effects were often 15 to 20dB lower in volume than the direct sounds from the sound system speakers. Seeing thousands of people responding at outdoor events is rarely duplicated percentagewise indoors, where the acoustics do not meet Bible standards. That also explains the higher response levels to outdoor events when no tent is used versus using a tent. When Jesus spoke to the multitudes, it was always outdoors. Except for when Jesus confronted the Pharisees, Sadducees, priests, and scribes in the Temple and Synagogues, almost all of the teachings to the crowds were done outside. Teaching the disciples and close followers was whenever Jesus knew they were ready to listen and save that knowledge for later when the Holy Spirit gave them understanding.

Church sound does have a huge, long-term impact on churches affecting their growth, health, unity, and support by members and the local community. What a church does after they have upgraded their sanctuary, is up to the leadership whether to promote the improvements or fall back and take sound for granted. From our experience, there has been no downside to making existing, and new worship spaces meet the Bible’s standard. True, no acoustics or sound system can save a person’s soul, but the quality of church sound can make a difference in reaching that soul.

In the end, upgrading the acoustics that will automatically get the best performance possible from the sound equipment of a church to help people with hearing issues alone. This should be enough reason for making such improvements. Upgrading to solve the congregational singing issue is another good reason. That solution is in the Bible too. The number one reason to upgrade is to have a church where no matter who walks through the doors in your worship space, when the person hears the Gospel message, there will be no doubts in what they have heard and no excuses in saying I didn’t understand the message. That said, no sound system or acoustics can remove the veil over someone’s eyes. That is the work of the Holy Spirit and whether the person’s heart has been opened to understanding and receiving the truth.
When Jesus taught, people either fled away or were changed by His teaching. Those who were being changed stayed and kept following Him to learn more. Those who fled, Jesus knew that they would never change because they loved or believed in something they thought was better, believed in other false gods or a lie. When that Gospel message competes with unmanaged reflections of sound in a worship space, those bad reflections will interfere with the person’s ability to understand the Gospel message. That is something that no one can measure. The idea here is to remove any possibility of bad acoustics and sound from keeping someone from understanding the message as no one knows the battle that is going through a person’s heart and mind when they are hearing a sermon at church.

Many times, ministers had shared with me how their ministry changed before and after the acoustics were upgraded. Some ministers have said, knowing a certain person who was at a point in their lives that they needed a push to understand salvation, the minister would prepare a sermon to reach that person. Before the upgrade, such efforts often lead to some people going to other churches, where they became born again. Perhaps the sound was better over there, or the minister was better at preaching. Who knows? After the acoustics were upgraded, most of those efforts in tailoring the sermons not only reached the person the minister was praying and preaching for, but sometimes other people responded to the same message. Sound quality can impact the confidence in efforts of the minister and everything else that happens at the front of any church. Who would have ever thought that sound quality in a church could affect the confidence of a minister’s ability to teach?

Sound quality does impact every part of church worship more than what people realize. It affects people physically, emotionally and it impacts how they respond to the Gospel. It is time for churches to get their houses in order and follow what the Bible teaches in something that we should not take for granted. If your church is dedicated as houses of worship to God, shouldn’t it SOUND like it is dedicated to God?

Bible Flow Chart from Solomon’s Temple to Modern Church Design

Posted by jdbsound on June 4, 2021

Here is an updated flow chart from Old Testament to New Testament, to help lift churches out of limiting themselves to entertainment styles of worship.

I think many people would agree that there is no experience better than singing in a church, with a congregation, and where everyone wants to sing.  Can you imagine singing in a church where 70% or more of the congregation sings all the time!  What a concept to be singing in a room where you know that your voice is contributing along with everyone else’s. Singing in unison or in harmony sounds just as heavenly and exciting—singing in a church where it sounds just as good with or without musical instruments contributing or leading the worship.  Many people dream of such a church sanctuary that performs like this.  Do such worship spaces exist?  Can a church be transformed into having such qualities?  

When only 20 to 30% of a congregation is singing, and the rest are passively swaying to the music, some with hands in the air and others almost dancing on the spot, is that the kind of worship the Bible describes?  Why don’t more people sing?  Is it because of the music, the hymns, the sound system, or could it be because the room is not able to support the kind of congregational singing described in the Bible?  If the room can’t support good congregational singing, that becomes an acoustics issue, and when most churches try to fix their worship spaces, they often kill the room to make the sound system perform better which makes the congregational singing worse – never better.

Evidence shows that it is easier for a church to resort to an entertainment style of worship because the secular community has not demonstrated any method of fixing the congregational singing issue in existing churches, and new churches opening these days are void of such performance qualities.  That then begs the question, is the entertainment style of worship honoring God?

In the Bible, there are no examples of musical instruments leading the singing, rather, the instruments followed the singing of the people.  When there is a worship team performing in most churches, the worship leader prompts the congregation to sing, and the performers who play instruments, follow the lead singers, not the congregation.  Often it is because they can’t hear the congregation singing at all, and they use floor or IEM monitors to follow the lead singers.  The reason the musicians and singings can’t hear the congregation is because of a room problem.  This creates a room full of people passively worshiping rather than actively worshiping.  That is not much different from going to a music concert.  Is worship in music as long or longer than the sermon? 

What does the Bible say about any of this?  God designed a house of worship in the Old Testament.  Why?  Why didn’t God leave it up to David or Solomon to design something that they wanted?  Why was God so heavy-handed and specific to its design.  Was this house of worship to be a relic of the past, something for the future – and something for the present? 

If the temple was to be a relic, then why are there so many specific details?  Why were those details preserved for over 3500 years?  What if in those details are solutions to many of the problems many churches have today – not just with sound problems, but other issues churches struggle with today? 

Study the flow chart. See what happens when 3500 years of history collide with science.  If there are any errors, let me know.  This work is a result of 27 years of fixing and documenting over 300 churches with another 100 plus churches that copied from the 50 church examples posted who informed me of their successes and from studying over1400 churches since 1983.  Visit my blog if you want to know more about the results in following God’s way to design churches and manage sound.

Half Round Diffusers vs. Phase Gradient Diffusers

Posted by jdbsound on May 20, 2021

Many people ask how the panels will look before looking at how they perform when it comes to acoustic solutions.  Here is a short video compare two acoustic treatments that can get similar results and the cost differences without looking at the aesthetics issue. Our experience shows that most church members change their opinions on aesthetics when the acoustical fix does a great job at fixing the room. Congregation members of most churches do agree with one idea. It seems that if the acoustic system fails at improving congregational singing, the panels on the wall have to look good as wall furniture. If the acoustic treatment improves congregational singing, how the panels look doesn’t matter. The aesthetic issues disappear. If you have any questions or comments, please post them below, and we will respond to them right away.

The great church carpet debate!

Posted by jdbsound on April 23, 2021

Should churches have carpet in the sanctuary and should there be padded seating?

Here is our latest video on this important issue.

Here are the details of how those values came to be.

The standard for a worship space to have a signal to noise ratio of 20 to 25dB and a flat response from 80 to 8000 Hertz comes from studying worship styles and working on hundreds of Churches.  First, you have to look at all of the various elements of worship.  They include:

  • Main Elements (Based on Scriptures and by Jesus Example)
    1. Reading of Scripture
    2. Preaching and Sermons
    3. Questions and Answers
    4. Prayer
    5. Celebration of communion
    6. Congregational singing
    7. Offerings
  • Secondary Elements (items that churches have added to worship after the reformation period.)
    1. Choir or choral music
    2. Music to support congregational singing
    3. Music lead by a worship team
    4. Announcements
    5. Sharing of testimonies
    6. Sharing of prayer requests
    7. Singing performances
    8. Music performances
    9. Music Rehearsals
    10. Child participation
    11. Congregational meetings
  • Event Elements (non-worship uses of a sanctuary.)
    1. Weddings
    2. Funerals
    3. Teaching Events
    4. Conferences
    5. Concerts
    6. Fundraising events
    7. Music Lessons

These are all of the main elements of how the church sanctuary is used over its lifetime.  Not all churches will practice these elements, but the first seven elements in the main portion are universal.  Now here is an aspect that is least understood.  If you have the ideal acoustic conditions for the first seven elements, the worship space can support all of the other elements that all churches will practice at one time or another.

For the rest of the article, here is a link to the PDF file on Carpeting in Churches.

When to Equalize the sound system of a new church

Posted by jdbsound on April 6, 2021

Whether a new church, after a church renovation or when converting a commercial building into a new church, the sound system is susceptible to humidity changes. The speed of sound changes as humidity changes. Learn about how humidity affects the performance of a church sound system and what you can do to keep your system in peak performance.

Do Churches that build what they want, get what they need?

Posted by jdbsound on January 19, 2021

When it comes to houses of worship, there is one fundamental question that Christians need to be honest with themselves.  Do we design houses of worship based on what we need or what we want?  The evidence that we can see and hear as a person visits houses of worship is that Churches are designed and built around what they want, and after they move in, they expect the building to give them what they need.  Many Churches seem to spend unlimited amounts of money after they move in to make the room give them what they need, and the results almost always come up short. 

Since the edict of tolerance by Emperor Constantine, there has been a search for the perfect house of worship.  It is supposed to be an ideal place for Christians to gather, hear the scriptures, study the Gospel and sing praises to God.  After building millions of churches around the world since then, that perfect worship space has been elusive.  When it comes to worship space design, it looks like the church is following a world view of thinking, which is similar to those who believe in evolutionism, materialism and atheism.  The evolutionist believes that if we keep building enough churches with random designs, we will eventually get it right over an endless period of time.  The materialist believes that there is a yet to be discovered equation that can explain to us how to create the perfect sound for worship.  The atheist believes that we can design churches without needing God.  Not one of these world view designs has created a building that meets all of the needs of Christian Worship as detailed in the Bible. Yet, every church, church board, and building committee prays to God for help in designing new worship spaces, but they don’t turn to God’s Word for answers as part of the process.  No one is answering the question of whether we are to design for what we need or what we want!

Why are Christians looking for answers to this problem outside of the Bible, the book that changed their lives?  The Bible, a timeless book, has a design for a house of worship that does give the Christian church everything that they need –  yes, even in these modern times.  The Bible teaches that the scriptures are sufficient to give us what we need and not what we want.  God is our loving heavenly Father, who wants to take care of His children.  GOD gave us a blueprint pattern to follow, which was designed by HIM through David in the Old Testament.  It is a perfect space for Christian Worship today. Shouldn’t the Christian community follow the Bible in what we need as a house of worship and leave the idea of what we want to our personal lives?

Acoustical Proof of Worship Space Failures

Posted by jdbsound on December 30, 2020

Almost every church has a sound system. It is supposed to be a tool to preach the Gospel message with. When that goal is achieved, it turns out that such a sound system is also excellent for the singing portion of the worship. In a survey done a few years ago, most church sound systems failed at meeting all of the requirements for worship. During the survey, approximately 90% of the worship spaces were limiting the performance of the sound system. In some cases, where churches had expensive “State of the Art” sound systems with the latest digital technology, the acoustical condition of the room limited the performance of the sound systems to 70% or less.

These sound systems were limited in many ways, including even when the congregation can sing over 85dB, but if the sound system was even louder than 83dB, people vigorously complained that the sound system was too loud. Other issues included the need for expensive drum shields, which can cost thousands. Many churches are turning to In-Ear Monitors, and all of the hardware needed to go with the system that cost thousands. In many churches, they were limited in the number of open microphones that could be used, or everyone had to have headset microphones and so on. What is also distressing is that most churches are investing more money into technology and replacing the technology in cycles of 15 years or less- long before the equipment is worn out or obsolete.

What would happen if you could fix the acoustics of the worship space permanently with an acoustical system that can be repainted in future renovations to last the lifetime of the church building? What if that permanent fix could get 90 to 100% performance out of your existing sound system or any future system expansion? What would happen if you only needed to replace sound equipment whenever it failed because of age, rather than trying out the latest technology? What does the latest technology get you in a room that is underperforming acoustically? Does investing into the newest hyped up devices, making promises that can only be reached if the room is fixed in the first place, do anything to help people understand the Gospel better, or is it better to just pacify people through a better entertainment quality sound system? What happens if we turn to the Bible to look for answers? The only example of a worship space is in the details of Solomon’s Temple. That was an edifice that was built over 3500 years ago, and if it was truly The House of God, then why did God allow it to be destroyed?

Is there any proof or evidence that if a church is designed like Solomon’s Temple as it is detailed in the Bible, it would not be suitable for modern worship today?  Are there any existing churches that have the same details of Solomon’s Temple, less the gold? If there is, how does it sound? If no place exists, then why isn’t there at least one?  Does Solomon’s Temple have anything to offer modern churches today? How can a building that some say is just a myth, a building that is said to have never existed, be relevant today? What could ancient technology possibly be usable in an ultra-modern church? Was there something that was in Solomon’s Temple that is usable in churches today, even if the modern church doesn’t resemble anything close to Solomon’s Temple? If the technology of Solomon’s Temple is transferable into existing churches, what does it say about the existence of Solomon’s Temple? Can a myth fix modern churches?  Has any of this technology been applied to existing churches? 

Jesus gave us the last supper, the communion that all Christians celebrate.  By that example, shouldn’t we follow the example of how to design a house of worship that Jesus designed – if we believe John 1:3 “All things were made by him; and without him was not any thing made that was made”?  Why do churches go against what Jesus did for us in this issue? After all, Jesus is alive today. Why do we treat Jesus as someone who is exclusively from the past?  When did Jesus and God stop being in the present?

In the Gospel of John, it begins with “in the beginning was the WORD and the Word was with God.”  This is about the past and how all things came to be.  At the end of the Gospel, after Jesus rose from the dead, John said, (John 20:31)  “but these have been written so that you may believe that Jesus is the Christ, the Son of God; and that believing you may have life in His name.”  Here, John clearly makes a transition where Jesus in not just the Son of God in the past, but is the Son of God in the present.

As a Christian, the teaching is that the whole Bible is the Word of God. The Bible is the word of God for the past – lessons from which to learn from; for the present – how we are to live day to day with God today; and for the future – to know where we go when we die and how the future of the world will be. Every part of the Bible has something to teach us today, and that includes what we should know about Solomon’s Temple. Was the destruction of Solomon’s Temple of God’s failure to protect His House, or was it to tell us that the details of Solomon’s Temple has valuable technology that is meant to be used in all churches after Jesus rose from the dead?  Here is a link that teaches about how Solomon’s Temple is relevant to churches today.

Here is a link to photo albums of over 40, of the 400 plus churches that have already applied this ancient technology of Solomon’s Temple with amazing results. Any church can benefit from this technology today.  The cost of such a system that can help save lives is priceless, but it is possible to add it to all churches, especially when it costs less than a typical sound system upgrade or replacement.

What Would Jesus Build?

Posted by jdbsound on December 2, 2020

Jesus would build exactly what he has already designed for us. Christian don’t follow what Jesus designed because most view anything from the Old Testament as something that is irrelevant today. That is from the old covenant. Oh!

In the New Testament, Jesus did not hint or suggest how houses of worship or churches should be designed, or did he? In Matthew 5:17 Jesus said “Do not think that I came to abolish the Law or the Prophets; I did not come to abolish but to fulfill.” Next we have to look at John 1:3  “All things came into being through Him, and apart from Him nothing came into being that has come into being.” When you read the first 5 verses of the Gospel of John, he is talking about Jesus. Jesus was there for creation, and all things were created through Jesus. Then when you skip to 1 Chronicles 28:19, King David told his son, Solomon, that it was the hand of God that guided him in the design of the temple. God also made him to understand what was being designed. When you put the other parts together, beginning with all things were created through Jesus, and nothing was created without Him, then that means it was Jesus who guided the hand of King David.

As a relic from the past, I can understand why people are so fascinated about Solomon’s Temple. The Ark of the Covenant, the gold on all of the walls and floor, and the gold covering the two giant sized Cherubs over the Ark of the Covenant. It all seems too good to be true, or is it? Since the temple was built and destroyed, many scholars, scientists and historians have been either, trying to validate its existence, seeking something spiritual, or think that there is something supernatural about the building. There are also people waiting in the sidelines for the chance to rebuild another temple. They all have their reasons, but most of them believe that there will be some kind of restoration, and building a third temple will move revelations forward. When man decides to build the third temple in Jerusalem, will not change God’s timing for future events. God will decide that and the unsaved people of the world will have one more chance to change where they will spend eternity.

When you think about it, the second temple, which was built with the best of intentions, was turned into an atrocity and few hundred years later. The temple was symbolizing all of the corruption and enslavement of the Israelites who were beaten into submission by the heavy burden of legalism enforced by the Priests, Pharisees, Sadducees, and scribes, long before the Roman Empire ruled Israel. When the Romans arrived, the religious leaders simply added some more rules to keep the peace with their new roman masters.

When you put it all together, Jesus designed the temple Solomon built. When you look at the temple from the perspective that Jesus designed it, then you should be asking the questions Why, and does it have relevancy today?

The knowledge of Solomon’s Temple that I am exposing has nothing to do with anything mysterious, supernatural or any mysticism. When Jesus cast the money changers out of the temple, he said “My House” in Matthew and Mark and said My Father’s House in John. Jesus said that the temple was His and His Father’s house. This was a copy, and a poor quality version compared to the first temple. Did Jesus claim this house because it was dedicated as God’s house or did He claim ownership because of where it was located?

For those who have come to realize this truth, Jesus didn’t have to give us a new church design in the New Testament. He already gave us that in the Old Testament, and when Jesus said he came to fulfill the law, I think he was also saying that anything that was designed in the past is a gift for us today. This may seem like a stretch, until you start applying modern science to Solomon’s Temple. You know – the temple Jesus designed.

Wait a second, are you saying that modern churches should be designed like Solomon’s Temple? Are you out of your mind? Who can afford such a building – consider this. When you remove the gold, you have the most compatible worship space to modern Christian Worship. They building method of the temple in modern times is a very affordable building that includes all the space a typical church these days needs. Ok then, are all churches going to look the same? The Holy Place or sanctuary portion of the temple is a roadmap that should not be compromised. How you design the rest of the building is up to you. Why would we want to design such a space? Perhaps it is because it is the ideal space to have the best worship experience possible on earth before going to heaven. It could be the closest thing to heaven we can experience here on earth, but we don’t know for sure because there is no building around that is completely designed that way.

Consider this, most church buildings cannot physically support all of the worship, detailed in the Bible in both the Old and New Testament, however, Solomon’s Temple, without the gold can. (There are already hundreds of churches that are using sound management from the Bible that suggests that Solomon’s design would perform even better.) Jesus had to have designed Solomon’s Temple. Why? So it can lay in a pile of dirt under a Mosque? Why else would Jesus guide the hand of David? What was so important in the design of the temple for the only man in History, David, to be touched by God? Many in the Bible have seen or been touched by Angels, but is was different for King David. The reason why it was Jesus that touched David, is because Jesus had touched people later on in the New Testament. Not even Moses or anyone else had such an experience until Jesus came to us in the flesh years later. Jesus said He came to fulfill the law. He had to, because He wrote them. It is possible that Solomon’s Temple was meant to be a gift for us to use today? Isn’t it time that we study God’s Word from a different perspective and embrace that gift and start experiencing church worship as God wants for us, or have we been too prideful and sinful to recognize His teachings, even when it comes from the Old Testament?

For those of you who think that Solomon’s Temple was a myth, how does a myth fix the performance of sound systems and acoustics in over 400 modern churches today? How many churches have to be fixed before using the methods from the Bible are considered standard practice in the Christian Church Community?

Half Round Tubes -Performance vs Aesthetics

Posted by jdbsound on June 9, 2020

Diffusers are amazing tools when used properly in a church. They solve a variety of problems in one step. Nothing performs better.

One question that is often asked, can you turn the diffusers sideways?  This is a great question, and the answer is based on our anatomy.  As humans, our ears are on the side of our heads.  This means we get our sound information for direction and clarity of speech on the horizontal plane or side to side. The time difference between our ears give us directional info to identify where a sound is coming from, and for speech, it helps us to focus on someone talking to us.

For diffusers to work correctly and to solve multiple problems in one step, their orientation is critical.  When applied vertically, the diffusers can solve between 10 – 29 acoustical issues in one step. No other acoustical system can do this.undefined

The problems solved or reduced are:

  1. standing waves
  2. deadspots
  3. hotspots
  4. eliminate echoes
  5. eliminate flutter echoes
  6. bass build-up,
  7. speech intelligibility,
  8. increases the signal to noise ratio up to 25dB throughout the room
  9. eliminate or less floor monitor spill,
  10. less sound system distortion
  11. less bass distortion
  12. helps to equalize the bass and mid frequencies
  13. gain before feedback,
  14. even distribution of sound,
  15. elimination of delayed speakers in most cases,
  16. better stereo imaging for stereo sounds (when the right equipment is used)
  17. higher attention span,
  18. makes the room easier for the musicians to perform
  19. improved sound for people with hearing aids
  20. better congregational singing
  21. easier for the sound-person to get an excellent mix
  22. it can reduce or eliminate the need for drum shields or both
  23. makes the room less fatiguing for the minister to preach
  24. fewer to no complaints if the sound system is louder
  25. improves the sonic quality of the sound system
  26. can add up to an octave of clear bass from the sound system
  27. better bass from musical instruments both acoustic and amplified
  28. it helps to make the room more relaxing to hear speech and music.
  29. lowers the sound levels from HVAC systems

If your church has a pipe organ, you will want to know this. One of the most interesting characteristics we have learned with using this method is that for some churches that want to maintain a longer reverberation time, plus have all of the benefits of better speech quality, the half-round tubes can increase speech intelligibility without changing the reverberation time. No other acoustical system can do that. For churches that have a pipe or electronic organ and want better speech quality, this method allows a church to balance the need for music and speech.

undefined

When diffusers are installed horizontally, the list of benefits is much shorter.

  1. standing waves,
  2. bass build-up,
  3. Helps to equalize the bass and mid frequencies
  4. It can add up to an octave of clear bass from the sound system and musical instruments.
  5. Can only reduce echoes, not eliminate them

There is more to these differences.  Because we have ears on the sides of our heads, the rate of control is exponential when the diffusers are mounted vertically.  One of the principals of how these diffusers work is by phase cancellation, which is the same technique as in noise-canceling headsets.  The more random the sounds are scattered, the more the overall energy is canceled from the physics principle of phase cancellation.  As a result, when mounted vertically, the diffusers can get up to 40dB of energy reductions or absorption by air friction.  When you mount the diffusers horizontally, you will only get about 10dB of the overall reduction.

The reason horizontally mounted tubes are less effective is because you are creating large reflective surfaces on the horizontal plane that reflects enough energy back into the room, which it is adding noise back to the listener that in turn, reduces the signal to noise ratio. This cancels almost all of the benefits of using half round diffusers horizontally.

Here is a simple experiment you can do yourself. Find a round container that is at least 7 to 8 inches round.  You can every use a large cooking pot, planter, or roll up some cardboard.  Now say a bunch of words into the side of the container vertically.  After talking for about 15 seconds, turn the container sideways, and talk for another 15 seconds.

undefined

What just happened? Like most people, they notice that when the container was horizontal or sideways, there is a distinct reflection. When you turn the container vertically, the reflection goes away.

This simple experiment demonstrates how powerful the half-round shape is.  In the vertical position, when the half rounds are placed on a wall in groups, you can adjust the spacing between the tubes to determine how much reflection you want, plus shape and equalize the sound at the same time.  This is a compelling way to manage church sound once you understand how effective and simple this system works.

Just as a reminder, for all churches, you have to have a balance between absorption and reflection. The half-round tubes are not always a one and done solution. It has to be part of an integrated system. Typically, for most churches, if you have carpeted floors and padded seating, that is often all the absorption needed. If your church doesn’t have carpet and padded seating, then you will have to add enough absorption to the walls to match what would be on the floor. That is a narrow window to get it just right.

For churches that play their music loud, some people wait in the foyer until the sermon starts or they wear hearing protection during the music portion of the worship service. With the half round system, it allows the sound system to perform 10 to 20dB louder with fewer people needing hearing protection. People turn to hearing protection when there is too much distortion in the sound. A distorted sound is irritating and painful to many. People turn to hearing protection, even when the sound levels are well below 85dBa. When a room is diffused properly with half rounds, it reduces or eliminates bass and mid-range distortion. With distortion out of the way, the sound at 85dBa becomes pleasant and easy to listen to. That pleasantness remains constant over 100dBc. Consider this – in a church with this kind of acoustical system with the right room shape and height, it is common for un-amplified congregational singing to be around 100dBc. When that happens almost no one complains. Why? Because there is no distortion. Half-round diffusers prevent distortion. This transforms any worship space into a music-friendly space at any sound level.

Church acoustics and amplified sound play a significant roll in the health of a church. When sound is good, it helps to grow the congregation. When sound is bad, it gets in the way of providing a clear message, that leads to less attendance which means fewer people tithing. In the end, there is nothing more important than preaching the Gospel in the best clarity possible.

To ultimately answer the question of Aesthetics vs performance, the smart answer is this. When an acoustical system works, people don’t mind how it looks.  If anything, they grow to like it.  When other acoustical systems are used, they often fall short on the expected and promised performance.  As a result, those systems become more like wall furniture and in some cases, artwork.  This drives up the cost of those systems.  Here is the truth most experts and salespeople will never share or admit.  To get the equivalent performance of the half-round tubes as a Do It Yourself project compared to ready-made products, the cost difference is 35 to 1.  A church that fixes their acoustics with cardboard tubes as a DIY including paint and hardware for a 400 seat church may spend $2,000.00 installed.  A ready-made system of equal performance will cost a minimum of 75,000.00 installed.  That is equal to fixing 35 churches of the same size.  Even if the same church buys custom made half-round diffusers, they may spend $20,000.  When compared to other acoustical system costs, that is enough money to fix 3 churches.

There is something to be said about how people react to anything put on the walls.  When people see cloth-covered panels, there is an expectation of good sound.  When that doesn’t happen, people often resign to the notion that the problem is too complicated and too expensive to be properly fixed or that the problem is impossible to fix.  Most people just put up with the problem and accept it as normal and don’t bother with complaining.  That is a lie created by bad information and myths that keep churches from getting the sound they deserve.  Sound excellence is a necessity, not an option.

When an acoustical system works, people don’t mind how it looks.  When it doesn’t work as promised, it has to look amazing.  Do you want a church that looks good and has fewer people attending or a church that is full all the time regardless of how it looks?

Church Sound. It’s all about cause and effect.

Posted by jdbsound on May 20, 2020

Sound system design has nothing to do with the equipment you use. It is about the location of speakers used to broadcast into a room and the interaction of the room onto the speaker system design.  It doesn’t matter if you are using line arrays or point and shoot speakers, if speakers are placed in the wrong position, both systems will have the same limitations.  It is all about cause and effect.  A sound engineer needs detailed knowledge, experience, and wisdom in understanding room acoustics or when to know enough to ask help from an acoustician to understand when to use which system.  Did you know that the room will tell you where the best places are to put speakers? 

The room will tell you when to use one of the following techniques:

  • Distributed Sound System
  • Central Cluster or single speaker system
  • Left Center Right system or cluster
  • Left Right System
  • Live Stereo Hybrid System
  • Hybrid Distributed Sound System

The geometry, reverberation, surface materials, acoustical management system, and room volume all have to be accounted for before creating a sound system design profile.  After all of this is done, you can start to determine the size of the sound system needed. 

If you think you need to do some acoustic treatment or the church has already been treated, it should not be using the spot treatment method, which means placing a few panels on a wall or two.  Whenever you add something to one wall or any part of a wall, it affects the whole room.  This also includes the placement of screens, lighting, and other items related to multimedia.  Even room renovations change how a room sounds. It is all about cause and effect. The acoustics of a church must use a planned system that treats the whole room.

A spot fix is when enough panels are added to solve one problem.  In acoustics, when there is a problem, there are always other glitches than masked other difficulties that you can’t hear and often are not shown in acoustical measurements.  Here is an example: Placing sound absorbers on the front face of a balcony will get rid of an echo.  However, the added absorption often makes the mids and bass stronger, which usually makes speech and music sound muddier.   This then requires adding bass traps, which are expensive.  While you can use aggressive equalization to make the sound system better for speech, you will need a different equalization for music.  While these efforts can somewhat help with amplified sound as long as someone remembers to switch the EQ settings, the congregational singing is degraded until bass traps are added.  Add the bass traps.  It is all about cause and effect.

However, you may have noticed at after treating the front face of the balcony and adding the bass traps, there is now a softer echo off the back wall or the reflections off the side walls are much worse depending on the shape of the room.  Reflections off the side walls are detected when clapping from the front of the center stage.  Those reflections from the sides or back interfere with speech and music intelligibility.  It is all about cause and effect.  Change the EQ of the sound system.  Helps for speech, doesn’t help for music at all.  In spite of changes to the sound system, speech is worse in the back half of the room.  Add speakers to the back half of the room.  It helps people with good hearing and doesn’t help people with hearing aids.  Add a delay to the speakers.  People with hearing aids do better, but they are still no happy because someone is sitting in their spot where they know the sound is better. 

Should you apply something to the sidewalls, then the echo off the back wall becomes much more pronounced and interfering with hearing on stage.  Switch to in-ear monitors.  It’s all about cause and effect.

Now the drums are too loud. Add panels to the stage or get a drum shield that costs more than fixing all of the acoustical problems in one step.  With the drum shield in place, the drummer plays louder because they can’t hear themselves properly.  The insides of the drum enclosures are easily overloaded, making it harder for the drummer to hear all the different drums and cymbals.  After additional dampening to the drums, the drummer playing even louder, getting elbow and wrist injuries.  Sound is still bleeding through the shield, even after adding a roof to it.  Some churches have turned the drum shield into a self-contained room with air-conditioning as a permanent fixture on the stage.  It is all about cause and effect.

For the time being, congregational singing has become a chore for most, resulting in less than 20% of the audience singing.  To get people singing again, you pay singers and musician to lead the worship, and to keep the talent to stick with the music entertainment program.  This helps for a while, and before long, you are back to less than 20% of the audience singing.  Bring in larger screens, add lighting effects, and use lighting to help create a mode to encourage people to sing.  Again, this helps for a while, but participation drops back to 20% again.  These objects change the acoustics of the room, and everyone just puts up with the sound degradation.  It’s all about cause and effect.

In the meantime, the sound system has been replaced, church attendance is up, but fewer people come to prayer meetings or Bible studies.  Turn to home groups.  At first, home groups bring in more people, but as the church continues to grow, more people are slipping through the system and are not included in the home groups or any spiritual support.  Fewer people are growing as there is no alternative for mid-week meetings at the church.   The preaching is dynamic; the entertainment is awesome, fewer people are actively involved in the church, and more people become adherents with no real motivation to join, and become members, and learn more about their faith.  The church is full of Sunday worshipers unable to defend the Gospel, but they know and singing the choruses sung by the church all the time.  It is about being part of something that is free of guilt, responsibility, and not knowing what salvation really is about.  It’s all about cause and effect.

Wait a minute, what does any of this have to do with acoustics and sound system?  The sound system is just equipment and technology.  The room is just a set of walls, floor, and ceiling.  When empty, they do nothing.  When energized with sound, there is an immediate cause and effect that impacts on every part of the worship service.  Sound affects how people react to events in a church.  Consider how people respond to movies at a theatre.  When the sound is excellent, the audience will tell you how good the picture looks.  When the sound is poor, people don’t come back.  How much more does that impact a church?  Again, it’s all about cause and effect.

Next, check the acoustical condition of your church.  Have your church properly tested for all aspects of worship, not just the performance of the sound system and hardware.  Test for congregational singing.  Test for audience participation for prayer and testimonies from the seating area of your church.  Check for the signal to noise ratio on the stage and in the audience.  Check the frequency response of the room and ignore the reverberation time of there is more than a 20dB difference in the response of the worship space.  If your worship space passed, then you don’t need any help.  Your sound system is already working perfectly.  If you have any concerns or want better performance from your sound system, fix the room.  It’s all about cause and effect.

After the sound system and worship space has been upgraded, start mid-week Bible Studies at the church.  If people come to the church mid-week, the congregation will become stronger and healthier.  Congratulation, you have just successfully upgraded the sound of your church to meet all what a congregation needs.

The story you have just read happens in many churches.  It is based on the testimonies of hundreds of churches around the world.  If this doesn’t sound like your church, have your worship space tested anyway if it hasn’t ever been properly tested. The results can be a surprise or a blessing.

What happens when Church Architecture, Technology, Science, and meets up with the Bible.

Posted by jdbsound on April 24, 2020

The Bible has a lot to say about how a modern church should be designed.  Solomon’s Temple was not just a house for God to dwell in, it was also meant to be a tool to help preach and spread the Gospel in the present.

After reading this article, please pass it on and make comments below.

***  Article: Gods Authority in Church Design ***

This article is the most comprehensive study of King Solomon’s Temple I have ever written.  If you believe John 1:3, then you know who really designed Solomon’s Temple.  King David only penned the details of the new temple.  King David told his son Solomon that it was the hand of God that guided his hand.  What was so important for God to design the temple rather than letting a man design in with whatever came into his thought?

This article gives a stronger case for what the “Inspired Word of God” means.

Winning people to Christ is not a game or something given to chance.  We need all the tools possible to have an impact on this world.  Jesus is Lord, and if your church is dedicated to God, Jesus is Lord over your church building too.

How to fix Congregational Singing Acoustically in any Church

Posted by jdbsound on March 6, 2020

Congregational singing is perhaps the third most important part of worship.  Prayer and preaching of the Gospel come first and second.  In many church publications and websites, there are many articles about how to improve congregational singing.  When you say improve congregational singing, what are you truly asking for?  In almost every case, they are asking how to get more people to sing.  And the theory is, that the more people are singing, the more they will be engaged.  The means of how they attempt this is with a high power sound system and strong leadership of the lead singer in a praise band. You never hear them suggesting to fix the room.

Here are some of those titles. 

  • 7 Tips To Encourage Singing in Your Church – Gavin Adams
  • Nine Reasons People Aren’t Singing in Worship
  • 12 Things to Avoid for Better Congregational Singing
  • Fifty Ways to Guarantee Poor Congregational Singing
  • How to improve congregational singing: 4 suggestions to …
  • A Simple Way to Improve Congregational Singing: Get Rid of the Carpet

There are many more.

The ideas recommended are extraordinary, and most of the time, they are putting the bulk of the load on the church leaders, including the pastors and song leaders. This is so wrong.  The truth is, all of the recommendations outlined are the results of trying to put a square peg into a round hole.  There is a simple solution to all of this.  When you read the articles, what church leaders are doing is a direct result of compensating for poor acoustical conditions.  Choosing the right keys to sing in, choosing a better selection of songs, hiring professional singers, and performers, in the end, it only helps things slightly.  The thing is, what the audience keeps telling me is that when they are singing, they feel like they are singing alone, it creates a sense of loneliness.  People feel as if no matter how loud they were singing, their efforts have no contribution to the overall volume of the congregation.  When you can’t even hear yourself, most people just give up and don’t bother singing.  Some may just mouth the words.

Sure, there are times when we see people at a concert singing a particular song, and it sounds impressive, but the reality is, those people will not sing the whole show at that volume.  It is more about having an emotional high and nothing more.  It is doing something to capture a moment for personal gratification and bragging rights.  That is not worshiping in any sense of the word.

My take on how to get the congregation to sing is by first identifying the source of why people don’t sing in your church.  In 90% of the churches that I have helped solve their congregational singing issue, it has always been around one reason – acoustics.  Here is some background you should know.

This is a new church with diffusers built into the walls. The quality of this room is such that when this photo was taken, the congregation drowned out the Pipe Organ. The organist said he pulled all the stops and he could not hear the organ for some of the songs they sang. At one point he stopped playing. With a sound meter recorder at the pulpit, the congregation hit 105dB several times and no one complained that it was too loud.

The struggles of congregational singing started long before the sound system was invented.  It is my belief that Choirs were formed originally, because when Christians first started to worship in existing pagan temples, (after the edict of tolerance,) most likely, those temples had such poor acoustics that the congregations back then had the same problem of not hearing themselves.  Then some talented singers found that if they stood in a particular part of a room, they could hear themselves and create an awesome sound of choral singing within the pagan temple.  That talent was later included as part of the worship.  When Christians started to build churches, when the buildings were finished, they asked the better singers to go to the part of the worship space where their voices were effective in creating this big sound where a few people would sound like many.

In the end, as more and more churches were built, the choir became the focus of congregational singing, and even though the congregation was encouraged to sing, the choir was the focus, not the congregation.  This continued throughout church history in one form or another.  Sure, some large cathedrals have these amazing sound effects. (Sound effects do not support congregational singing or speech.) Still, in the end, it is the choir and the organ that dominated worship, not authentic worship singing or hearing the Gospel.

Throughout the Reformation period to today, churches have been experimenting with worship space designs to discover the Rosetta stone of church acoustics.  Churches have been trying to create a worship space without any acoustical planning.  It hasn’t happened yet that we know of and if there is a church out there that works, where is it?  Why would it be kept as a secret?    When the room helps the singing of the congregation, the congregation will sing, and they will sing as loud as they are inspired to.  The same properties that makes congregational singing work, speech will be equally as good.  Around the world if there are such churches that have the proper balance of sound, for speech and congregational singing, why has no one documented these jewels or studied them to see what makes those churches better than others.  No one has made permanent records for future churches to follow. 

It seems that when a church gets known for its musical performance quality, it usually suffers from speech, and for years people have been brainwashed into believing that you can’t have a worship space that is good for both speech and music.  That comment is true, for a musical performance space or concert hall.  This is not what a church needs. A church needs a room to support congregational singing, not musical performances. 

When I get hired to fix a church, one comment that is repeated often is, we can’t afford or don’t want a concert hall.  That is the whole point.  You don’t want a concert hall, and it would be detrimental to a church to have such a space.  Concert halls do not support congregational singing, none of them do.  Concert halls are awful for speech.  If you look at most concert halls today, when it comes to speech, they close curtains, expose absorption panels, and they rely on costly sound systems to broadcast speech events.  Concert halls are either-or spaces.  They cannot support speech and music equally.  Furthermore, they don’t support audience singing at all.  How do I know that?   When I go to most of the churches that I have fixed in the past, when the attendance is around 90%, the congregation can drown out the pipe organ, the electronic organ, and the amplified worship team.  Yes, it is possible for the congregation to drown out a sound system with professional Christian performers leading the music.  That is what good acoustics can do in a worship space.  When people try to sing like that in a concert hall, it sounds like chanting in a sporting event.  It is not very musical and singing in four part harmony is out of the question.  In a worship space, a well-motivated congregation can sing over 105dB with the sound system off when the acoustics are managed for congregational singing.  If only the sound system could perform that loud without distortion and without the congregation complaining about the loudness.

Consider this, the invention of the sound system and its introduction into churches merely ushered in over time, the ability for contemporary worship, with the goal to get more people singing.  Yes, many churches tried amplifying the choir as a means to get the congregation to sing, it didn’t work.  When it came time for speaking, the sound system failed as well to amplify speech properly without feedback – This created a dilemma.  To make the sound system perform better for speech, churches add absorptive flat panels, and that usually means killing the room, which in turn, discourages singing.  The sound system was believed to be the solution to improving worship, but the truth is, the sound system can only amplify what the room allows.  In this struggle between the sound system and church worship, no one looks at the room as being the limiting factor.  Instead, observers and people asking whomever as to what can be done, the fingers point to the technology, the pastor, the song leader, and the soundmen who get all the blame.  All of the other recommendations are meaningless until the room is fixed.

The only complaint this church has is that congregational singing is much louder up front.

As I mentioned earlier, I fix the sound in churches all over the world.  Without changing the leadership, the pastor or song leaders, and without changing how worship is conducted, with the methods I use, most congregations go from 10 to 30% of the audience singing to 65 to 90% of the audience singing when the room is fixed.  That happens because there is a way to make the room very responsive to exactly what people need to hear and feel during the singing portion of worship.  At the same time, the same system improves the quality of speech, and as a bonus, the performance of the sound system increases substantially more.  Doing church acoustics correctly, is being able to have a room that does both speech and congregational singing equally well.  It also winds up being a good room for Christian concert and drama performances.  Is it really possible to have a worship space that does everything well?  Yes.  Should you think that this is about a compromise? Think again, it is not.

The method of sound management that I have been using in churches is not of my design.  I cannot take direct credit for these successes.  I learned from an expert in Church sound.  This sound management system that is now in over 450 churches, is the same method as originated by the hand that guided the fingers of King David, who designed King Solomon’s Temple.  The acoustical system that I use is the same system that was designed by God.  As I said, I can’t take credit for the success in the churches that have this system.  Here is condensed version of how I learned about it.

Years ago, I had read or heard this verse in 1 Kings 6:29, which says that on all of the walls within and without, there were carvings of Cherubs, Palm Trees, and open flowers.  Then one day and as the pastor was reading this passage from the pulpit, it dawned on me that the palm trees seemed out of place.  They have no aesthetic value.  There is no spiritual, nor ritual reason for having palm tree carvings on the wall.  Then the acoustical knowledge I was learning at the time kicked in.  If there was no acoustical treatment within the temple, the Levite Priests would have not been able to understand each other.  That room would have been ringing well over 5 seconds.  Under those conditions, even at 24 inches, the reverberation would have made it difficult to impossible to understand speech.  It says that in the large room of the temple called the Holy Place, that the priests taught, they read the laws, they played musical instruments, they sang and prayed.  They also did rituals that would have involved speaking.  What was in the room that allowed them to do all of those activities, which are also the same actions we do in churches today?

After doing a lot of testing and experimenting, I discovered that the shape of the palm tree could be mimicked with cardboard, wood or plaster tubes which come in a range of costs, depending on how important aesthetics are and the budget your church can afford. This changes the performance of any existing church into a high-quality worship space that supports both congregational singing and speech.  Before installing any churches with cardboard tubes, we tested a number of churches.  For the first church tested with cardboard tubes, we used 10 and 12 foot long tubes, leaned them against the walls of a church and left them there for three weeks.  At the end of three weeks, not only was speech so much better, but the number of people participating in congregational singing doubled.  This was a huge surprise, and it was unexpected. We repeated this test in a dozen churches, and all of them had similar results. With those outcomes, I started recommending churches to use half-round tubes around their worship spaces, and every time as a new installation was completed, the results were almost all the same. (Let’s face it, some room shapes are better than others.)  Speech improved, and congregational singing always was much better.

In most cases, at the 6th month follow up to an installation, the contact person would tell me two things.  The first was an attendance increase.  The second was that 65 to 90% of the congregations were singing every song.  In most cases, there was no change in leadership, or order of worship or how singing was conducted.  All of the deadspots in the room were gone.  Now you could sit anywhere and sing out and feel like you are part of something big.  Sometimes I also got glowing reviews of how the sound system was fixed when nothing was done to the system except for some equalization. 

Since around 1994, over 450 churches have applied this method of managing the sound in their worship spaces.  All of them have reported similar results.  The interesting thing was, most of these churches didn’t hire me to fix their congregational singing.  They hired me to improve the performance of their sound systems.  They wanted better speech intelligibility.  The half rounds tubes are the most cost-effective solution to improving the performance of any sound system.  This method fixes the sound system much better than using any absorptive panel. 

There is also a unique feature that half-round tubes have that no other acoustical system can do.  The half-round tubes, when laid out in a specific pattern, can equalize a room.  By adjusting the spacing, the sizes, and when using prime number sequences, if there is enough wall space, you can cut up to 40dB of excess sound energy from 50 to 1200 Hertz.  If your worship space has excess energy, for example, at 400 Hertz and it feeds back there all the time, you can space the diffusers to cut out that frequency range.  No other acoustical system in the world can do that.  The most powerful acoustical system in the world comes from the Bible, and it is designed by God.  Many people say that the Bible is sufficient in all things, and this is another example of that Biblical truth.

We have to stop blaming worship leaders, song leaders, and pastors for the lack of congregational singing.  Saying things like changing the key to sing in or changing the order of music is blaming the worship leaders, and because of acoustics, all of their efforts cannot get any significant results because the room will cancel their efforts.  Song leaders are always searching high and low for answers, and if you watch them carefully, they are constantly trying new things to get the congregation to engage more.  Sure, for the short term, they might get an additional number of people singing, but after a few weeks, it goes back down to where it was before.  It’s not that people don’t want to engage; it is because the room will not allow them to participate in group singing.  This is the real reason why so many churches with contemporary worship styles have sanctuaries that are as good or better that performance clubs in Las Vegas.  So many churches have turned to an entertainment style of worship.  How un-Biblical is that!

On the internet, there are plenty of videos of young people in churches with hands up in the air and swaying to the music, but if you look closely, most of them are just mouthing the words, they are not singing.  That is not worship.  When what goes on in a sanctuary looks more like a rock concert, it is not church or worship.  It is just clean, mostly unspiritual entertainment. 

If there is any blame to go around, here is an uncomfortable truth.  When I am hired to help a church, congregation members always tell me how, for years, they have been complaining to the church elders.  Since churches are so reluctant to share their experiences about sound to other congregations, most church elders feel helpless because there are no standards for church sound and acoustics for them to turn to.  When they ask consultants for help, they say, ask 10 sound guys what to do, and you get 10 different answers.  This madness has to stop.  The Bible has the answers to church sound, and it is a solution that is superior to any other system at any cost. 

The best way to improve congregational singing is by fixing the worship space to the same standards as outlined in the Bible.  In the end, this is the only option.  If your church already has more than 65% of the audience singing, you are most likely not having an issue of the congregation being engaged in worship.  For the rest of the churches out there, seek out what God can do for you.  You don’t need an expert or acoustical consultant or sound system engineer to have a successful transformation.  Churches can do this on their own.  All you have to do is look at the examples on my website and copy whatever layout you see.  If you need more help and can afford the cost of a consultant, hire one who understands the Biblical way to solve church sound problems and congregational singing.  There is no mystery or formula or program when solving the congregational singing issue God’s way.  Congregational singing is also a spiritual issue.  It is what binds up together as believers.  Stop solving spiritual problems using mans’ ways.  God’s way always works.  Don’t take my word for it.  Trust God.

What are your Church Priorities about sound when it comes to preaching the Gospel?

Posted by jdbsound on February 25, 2020

Is the performance of your worship space a priority?  Is the message always crystal clear in every seating position, and over 60% of the congregation is singing all the time?  If you say no to either or both questions, and you want your church to sound right for speech and music, the biggest obstacle is often the acoustics.  The second is money.  The third is aesthetics.

Fix the room!  How?  Follow what the Bible says, and you will not be disappointed.  After all, it is God’s plan, not man’s idea.  Do you think that the results will be less than perfect if you follow His plan completely? Isn’t the Bible the Living Bible?  Since when did the Bible stop teaching us new things about science?  Check out Solomon’s Temple, and the answers are there.  They always have been. It’s just taken a while to join the dots.

But it costs too much!  Oh, you mean the cost of a few floor monitors or a couple of wireless microphones considered too much?  That is often the cost of the Bible’s way of fixing the acoustics or about $3.50USD per seat for a 300 seat church. (Not including the price for the knowledge of knowing what to do.)  Replacing a mixer costs about $15.00-21.00 per seat.  Replacing pews for chairs cost about $75.00 per seat.  Buying 10 Shure SM58 mics with cables and mic stands – costs about $1,500.00.  Fixing the acoustics of a church is cheaper than you think.

If the look of any acoustical treatment is a concern, ask yourself this.  Are you there to worship God or the building?  Fixing the acoustics is like saying you are more interested in hearing what God has to say through your minister.  Putting up with acoustical problems, poor quality congregational singing, and accepting a sound system with limited performance is like saying the building is more important than the message and having fellowship with other believers.

It all comes down to priorities.  The primary purpose of any building that is a dedicated House of God is the preaching of the Gospel.  A place where the Gospel message can be spoken without distortion or interface.  That includes making the room behave as God would want us to have it.  The second priority is the breaking of bread and drinking of wine in remembrance of what Jesus did for all of us.  The worship space has to support this event as often as each church chooses to remember.  The next priority is congregational singing.  There isn’t any other experience that can replace the joy and excitement of a room where more than 75% of the audience is singing.  Songs that tell stories of Jesus, his atonement of our sins, and of people who follow Jesus are powerful in bringing people together.  It takes the same quality of acoustics to hear clear speech as well as great congregational singing.  These are the things that matter when you are a part of the Kingdom of God.

While I do have a business about church acoustics and sound, there is no possible way for one person or one company to fix all of the churches out there that need help.  By making this public, it means that no one can patent it and force churches to pay a license fee. It means that no one can control it and inflate the cost of fixing existing and new churches.  Churches should use the Bible’s methods with confidence, to apply in faith what God teaches, even without expert help.  When churches take such a leap of faith, in most cases, the results are outstanding.

This information is being shared because I care more about winning people for Christ through better sound than creating a business empire.  By revealing what the Bible teaches, by showing that science backs it up, that it is affordable for every church to have excellent acoustics, this is all part of the Great Commission.  If more people with a passion and skills like mine, were to apply what the Bible teaches about sound, we could make a difference.  Mat-7:15.  Beware of false prophets, which come to you in sheep’s clothing, but inwardly they are ravening wolves. (KJV)  If you have the chance, read the rest of what Jesus said in Mathews 7:15-20. Don’t trust me.  Trust the Bible.

Is your minister preaching a distorted message unintentionally?

Posted by jdbsound on February 17, 2020

When sharing the Gospel, so many times, someone has said that they didn’t like what the minister said during a worship service, so they left the church.  They thought the minister was preaching a false message.  Some people have told me that they walked out of a worship service upon hearing the distorted message.  I would ask them if other people left the service at the same time.  In every case, they said no.  That is when I try to retrieve the audio record of that specific service.   As it turned out, on the recording, the minister said the right things, but why was it heard in the sanctuary as something else? 

The next step was to play the recording over the sound system and sit in the same spot the person complained about what he heard.  Sure enough, the same gibberish that got the person upset was heard in that spot.  When you moved several feet over in any direction, the sound was clearer, yet in other places, different words were being twisted.  With the recording on a loop, we found dozens of other places where the minister’s words were warped into something else.  Doing this exercise did get one person to try church again, but in most cases, when something like this happens, most people will not return to a church where the Gospel is preached.

Sound quality matters.  What good is excellent speech intelligibility in one spot and a failure in another?  Sound quality can save people and their souls.  I have never met a person who was saved by a song, but I had met many people who were saved when they heard the clear and undistorted message of Jesus Christ and become followers of the Messiah because the message was clearly understood. 

I often wonder how many other people have experienced hearing something different than what the minister said in a sanctuary. For many ministers and church leaders, it would never occur to them that the sound system was the cause of some people not returning to church.  The unfortunate truth is, many churches have questionable acoustics, and when a person sits in a spot where words, syllables, or the sound volume is too low, what was said and what is heard were not the same.

Sound systems cannot fix the acoustical problems of a church.  Adding more speakers or applying the latest state of the art technology tricks are no match to Architectural failures in room design and unmanaged sound sequencing around a room.  Absorptive panels are often the first weapon used to tame a room.  Cutting down on the noise and reflections with absorption cannot fix deadspots or hotspots.  Absorptive panels cannot change the path of sound reflections that causes uneven sound distribution. Absorptive panels have been known to make the sound harder to understand in those poor locations throughout the room, not better.  What is needed is a different weapon to defeat poor sound.

To eliminate hotspots and deadspots, you need to be able to distribute sound more evenly.  Scattering the sound is the most effective way to create a unified sound field throughout the whole sanctuary.  When sound is managed in this way, not only does it eliminate deadspots and hotspots of any speech problems, but it makes congregational singing, praise and worship bands clearer, the stage sound is corrected, and for many churches, they bring back choral music because it sounds better than what a worship team could do before the room was fixed.  In most cases, scattering the sound costs less to do than absorbing sound. 

Acoustical solutions for churches that work should be common knowledge as these concepts have been around for years. Fixing a church can often be restricted by how a solution may look. It is high time that the aesthetic police take a back seat from preventing the Gospel message to be preached clearly.  If aesthetics are a big deal, alternatives are always possible.  In the end, it is all about priorities. You have to choose between hearing the Gospel or have a Church that looks good.  What will your church do?

The Father of Modern Day Acoustics, Wallace Sabine and Solomon’s Temple

Posted by jdbsound on February 5, 2020

Introduction

In the field of acoustics and sound, many have said that Wallace Clement Sabine is considered the father of modern-day architectural acoustics. His scientific work was not only the foundation for concert hall acoustics, but few are aware of how his work has impacted the church community around the world. According to several sources, he was raised in a protestant home, but as an adult belonged to no church and professed no religious faith, yet his work has impacted churches in ways even Wallace could not have imagined. Wallace’s work included figuring out a prediction model of how to apply absorption to tame a room. He also proved that the reverberation time alone is not enough in helping performance spaces with their sound needs. He laid down a foundation, showing that you need much more detailing and care to create suitable sounding spaces, not just for concert halls, but for full Christian worship too.

Shortly after his discoveries and successes, most acoustical experts, Architects, engineers, and audio experts have focused on one thing, the reverberation time of a room – ignoring much of his actual contributions to modern acoustics. When Wallace created the first equation to calculate how much absorption is needed, most people thought that this equation was something magical. It was almost as if a single number could solve all sound problems for concert halls and performance spaces. While such a numeric value is essential, it was a small part of a much larger picture. Sure, Wallace did devote a lot of his time to such studies. Unfortunately, the absorption calculation moved from being a small tool as part of a broader view of performance acoustics to becoming the only thing that mattered. This equation gained mythological-importance to the point that for many laypeople….

Once again we see science and the Bible in almost perfect harmony. Within science, there are many tools. For acoustics, there are specific tools. With the help of the Bible, it requires a set of tools that are unique to churches. For concert halls, recording studio’s and other entertainment venues, there are a set of tools for each one. Most of those tools do not apply to churches. When the tools of an acoustical consultant don’t use the Biblical tools exclusively, you will always get the acoustical performance of what those tools were based on. If you have only concert hall or studio or entertainment tools, then the results will not meet all of the needs of the church. If you use Biblical tools, you wind up with a House of Worship as the Christian community should have, but most churches don’t have a clue of what they are missing out.

Solomon’s Temple was very detailed in how it sounded. If you believe in the Trinity as I do, because of John 1:3 you know that Jesus design the temple that Solomon built. Without the acoustical planning in Solomon’s temple, the Levites would of had to have super natural powers to hear each other within the walls of the temple. There is no record of the Levites having such powers. What did they do to the temple to make it possible for people to hear in such are large space?

Here is something to consider. If Solomon’s temple is a myth, then the details of how the temple walls were completed should not have survived over history. After all, there is no record of the interior of Herod’s Temple other than some carving on the ceiling that Herod ordered which is not in the Bible. If someone says the Scriptures are not the inspired word of God, then the details of Solomon’s temple wouldn’t matter. But what happens when you apply the details of Solomon’s temple to an existing church? If it is a myth, nothing should happen. If it fixes a church, doesn’t that prove God, Jesus and the Holy Spirit? What does that mean if over 400 churches have applied such a system in faith, using the same methods from the Bible to make the acoustics of their churches as best as they can be?

The details of Solomon’s temple matters. Nothing in the Bible is about trivial nonsense. Everything in the Bible has a purposes and the details of Solomon’s Temple is a roadmap to fixing existing churches and it should be a template for new churches today now that we understand why such details were persevered for us in the scriptures today. How many more churches need to be convinced before it becomes a normal way to complete our houses of worship?

If anyone with normal hearing in a church has trouble understanding what is being said in God’s House of Worship, the Bible has the solution for that. And that solution is very affordable. Please enjoy the rest of the article.

The Father of modern acoustics

Is Church Acoustics Easy?

Posted by jdbsound on December 23, 2019

There are two answers to this question. When you follow just the science, the correct answer is no. When you follow what the Bible teaches, the answer is yes.  Church acoustics is simple, but many will tell you otherwise. While it is easy to change how a room sounds, it is another thing to change the sanctuary to perform appropriately for a complete Christian Worship experience regardless of the denomination or congregation you belong. Christian Church worship is unique and the acoustical requirement of any church cannot be found, practiced or learned outside of any church community adequately.

Concert halls, recital halls, recording studios or any room where non-Christian people revere as great places for music or live stage performances and entertainment, these places have clouded, (Mat 7:15) the judgment of churches communities all over the world for years of what Christian worshipers need in a large room. When we turn to the Bible for the kind of worship space we are supposed to have, the answers most Christians are looking for are right there.

Science has not caught up with what is required for church acoustics. It is not able to predict the perfect acoustics a church needs. In each generation of computer modeling, it is getting much better. The good news is that we don’t have to wait for science to catch up to modeling proper worship space acoustics. The Bible has always had the solution as a tool to solve or plan church acoustics, even in the 2100 century. When such planning is applied the outcome is still what a congregation wants and needs. Here is a prime example of Biblical Scientific Foreknowledge at work. When we look past the Golden walls and floors and peel back the details of how Solomon’s Temple was designed and finished, we discover a worship space that every Christian congregation should have today.

The Bible has always had the proper teaching or formula for large room “Worship” acoustics. Did you know that without God’s design for acoustics, the Levites would not have been able to do any ceremonies or teaching in the temple? In Solomon’s Temple, there was an acoustical system given to Solomon that was applied. When employed in modern churches today, it solves almost all of the acoustical problems we can often hear and it makes the worship space better for congregational singing every time. Hundreds of churches have already been fixed or planned in this way. How many more before we can trust the Bible for modern church sound needs?

For church worship, whether in a classical or modern church structure, a commercial space, or converted space, there are many performance requirements to obtain the full worship experience which includes hearing the Gospel unfiltered by the poor acoustical performance of a sanctuary. (Poor acoustics acts like a changing filter that pollutes the Gospel. It can make similar words sound different which changes the meaning of what was said. For people familiar with the Bible, this may not be that big of an issue but for a person who has never been to church or is unfamiliar with church speak/language, when the room changes the pronunciation of a word, it can change the meaning of what they thought they heard. A church with the proper acoustics will prevent most of these mistakes regardless of what a sound system can do.) There is preaching, prayer, congregational singing, testimonies, choirs, worship teams and worship concerts. All of these parts of worship have to perform equally.

Church acoustics is not straightforward without the Bible. It is very complicated and any person designing an acoustical change should be including all aspects of worship, not just making a quick fix because of an irritation. As more churches recognize this truth, many are fixing existing past acoustical treatments that were done with good intentions and without help from the Bible. For example: Many people working in live sound don’t know that most hotspots and deadspots are acoustical problems and made worse when the wrong sound system design is installed. If your church has the right sound system design and there are still places where the sound levels and speech intelligibility is a problem, the sound system is telling you or screaming that it is a room problem -even if there is not feedback noise.

Church acoustics can be confusing, even with Biblical help. Experience has shown that there can be three churches that can have the same shape, dimensions, and age, and all three worship spaces different acoustical fixes. On the other hand, you can have three churches of different shapes, different dimensions, the same seating capacity and from three different ages and yet the acoustical solutions look almost the same to get the best performance for speech, prayer, congregational singing, choral singing and worship team performances. These differences in acoustical treatments are not easy to figure out regardless of the sound system design, equipment, and operating skills.

If the reverberation time is too long, don’t just fix the reverberation time. There are always at least two to five other problems that are being masked by the long reverberation or long time of noise. Correcting only the long reverb time, in most cases, exposes or creates bass problems that weren’t audible before, but the acoustical measurements said that such a predicament would happen. When the subs don’t sound good, you put a cage around the drums and you can’t mic the choir. When the floor monitors are too loud or as loud as the FOH speaker system and you are forced to get in-ear monitors. Then you have to get the worship team members to sign a waiver to not sue the church for premature hearing loss. Fix the room properly to meet all aspects of worship and you can avoid all of these issues.

Church acoustics is complicated and people who do Recording Studio, Concert Hall, Recital Hall, and noise control acoustics all have good intentions in wanting to help out a church. If their solutions are not based on what the Bible teaching, sure, they can change how a room sounds, but will their fixes be what a congregation needs? The choice is yours.
What is rarely taught or shared except on this website, is that a sound system is a magnifier of how a room performs. If the acoustics and shape of a worship space work, the sound system will tell you by how well it performs. If the acoustics are wrong, the sound system will be limited in what it can do. If after changing the sound system twice in the last eight to ten years, didn’t make that much of an improvement, do you really think a third sound system will be any better?

What is also not taught is that it is cheaper to bring a sanctuary up to worship space requirements that support all aspects of worship than to upgrade a typical church speaker system that can only make an incremental improvement for amplified sound. Fixing a room that meets worship space requirements often makes the current sound system perform profoundly better (unless the sound system is so poorly fabricated that it needs to be redesigned and reinstalled if the hardware is up to the task.)

Church acoustics can be easy when you follow the scriptures. Jesus never spoke of this because he already has given us the plans. Jesus said in Mat 5:17 “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them.” The Bible also says that all things were made through Him from the beginning. Jesus could not abolish the laws He created with His Father and the Holy Spirit (John 1:1-4.) There are many churches out there with poor sound, poor acoustics and have members who want to experience the full Christian life including the complete worship experience we all should be having. When you look past the gold and wealth surrounding Solomon’s temple, you will discover a blueprint from Jesus of how all worship spaces should sound. If that means duplicating Solomon’s Temple, that is what we should be doing. How is that so different in the fact the every church practices communion in one form or another. Every church has prayer, singing, reading of the scriptures, sermons and fellowship of its followers. Every part of a person’s life is in the Bible, whether any person can follow it 100% of the time or not. The same should apply to the houses we call churches that are dedicated to our Lord Jesus Christ.

Does Your Church Need help with Sound?

Posted by jdbsound on August 1, 2019

Here is a collection of 445 photos of 46 churches that completed most or all of their sound system and acoustical plan.  My job is to design a solution that will solve all or almost all sound problems in one step.  For most churches, this means getting the most accomplished in one step as most churches can’t afford to keep chasing sound problems without truthful help.  The road back to great sound in the church is in the Bible, and that is what these churches did. 

All of the installations of the acoustical systems and the sound systems were completed by church members or local contractors when those churches were able to afford professional installers.  The final appearances are what those churches selected.  I work closely with all churches for alternative aesthetics regardless of any budget limitations.  When a church has to choose between aesthetics vs. performance of the 400 plus churches that have just simple painted cardboard tubes on the walls, those churches spoke with what they installed. 

These churches demonstrated that they care more about hearing the Gospel than having a sanctuary that looks good.  There is a high spiritual cost for poor acoustics and sound system designs.  Poor sound does get in the way of people hearing the Word, and for some, it can deny people from understanding the Gospel message of salvation, and that is a cost no church can afford.

For professional, no compromise help, we can provide the highest level of expert assistance that will fulfill the Great Commission as Jesus taught. Having the skills of the world helps but God’s plan for churches demands His way of doing Church Sound. Without that knowledge, the worlds way of doing church sound always comes up short in meeting the standard that God demands of us.

The Scientific Foreknowledge the Bible Teaches about Church Sound?

Posted by jdbsound on July 26, 2019

Here is a fresh look at Solomon’s Temple and how it relates to Modern Churches today. Here is link to a 13 page article about church acoustics from the Bible’s point of view.
The Scientific Foreknowledge the Bible Teaches about Sound and Acoustics?

Introduction

The quality of church worship is critical to the health of a church.  The better the excellence of worship is, the stronger the church will be.  Quality of worship is not about packing the church full of people for the sake of filling a worship space so much that it becomes necessary to keep building bigger buildings.  We worship God, not buildings or pastors or knowledge.  It is the Gospel, the Bible that leads us to God.  It is God’s words that keep us in a relationship with Him.  The strength of a church is not measured in numbers in the seats or money.  Jesus taught us to feed the hungry, clothe the poor, and shelter the homeless.  The Bible teaches over and over again that we are to live by example (Psalms 1:1-6), to be a light in the world (Matt 5:16), when they see that we are different (James 2:14-26), it will be that difference that will attract people to God.

The strength of a church is measured by how people support each other, and by how much a congregation supports each other as a family first, as brothers and sisters, and then the local community.  Is the church feeding the hungry, clothing the poor, and sheltering the homeless?  The modern version of Jesus teaching for us in countries with a democracy and wealth should look like this.  Is the church cutting lawns, clearing driveways, cleaning people’s homes, fixing up members and non-members homes?  How often are church members spending time with the widows, the singles who have never had a partner, or the elderly?  Are these not the things included in what Jesus told us to do?  Are not these the same teachings in the Old Testament?  This is just a small sample of how Christianity should look like to the secular world.

After reading the full article, please comment on it. We want to get this right as the church community needs this knowledge. If you have any questions, want to learn more or see a presentation about Solomon’s Temple and the Modern Church, contact me here – jdb@jdbsound.com

You church may be one of those that has great sound for all parts of the worship service. If it is, you should let everyone know as it will help to bring more people in. You should let us know so we can tell others. If you find this article helpful, please pass it on. Pass it on to your pastor, your friends and family. Give them the chance to learn what God can do for them today!

Thank you.

All modern churches can benefit from Biblical Acoustics
All older churches can benefit from Biblical Acoustics
