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?

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

Churches are Tools

Church Ceiling Height Chart

Posted by jdbsound on December 26, 2018

There are three key parts to what happens in church worship.  There is the spoken word, there is collaborative/congregational singing, and there is performance singing.  For a worship space to support these three events where speech is first, then congregational singing and performance singing, you need a specific design and dimensions to support these functions well.  High-quality speech should not come at the expense of the music.  Music should not come at the cost of speech.  There is a balance, and part of that balance is to have enough ceiling height to support both speech and music in a contained space.

Unfortunately, churches these days are building lower and lower ceilings in their worship spaces.  A person can assume that when so many churches have experienced only poor quality acoustics, many wonder what is the point of building a taller worship space.

When a church builds a low ceiling, it limits congregational singing and it makes you more dependent on technology, but guess what!  The same things that limit congregational singing are what also limits the performance of the technology we affectionately call the sound systems.  So, instead of getting 100% out of your high quality, expensive sound system, you’re getting only 40 to 60% of the sound systems’ true performance abilities.  It is actually cheaper to build higher than the added cost of un-needed audio technology to make up the difference.   The chart below should clear the air as to the minimum height your next church should be. If you can afford to build higher, do it.  Also, a taller worship space does not mean being stuck with longer reverb times. A higher ceiling means natural room reverberation can be adjustable and is tune-able.  With a taller ceiling, you can change the frequency response of the whole room without needing a sound system or equalizer.

Church height is important for a worship space.  One of the biggest parts of worship is singing.  Congregational singing to be specific.  When singing as a group, several elements are required for a good and healthy worship experience.  There is chorusing, harmony, sound volume,or loudness of the singing and being able to hear yourself as well as the people around you.  When all of these elements are in balance, the worship experience is like no other.  The majority of people get a lot of satisfaction from the singing experience during worshiping in rooms that have ceiling heights that match the size of the seating capacity of the worship space. The above chart is the minimum of interior ceiling heights.  If you want to build higher, you can as the singing experience gets even better.

High ceilings allow for better sound system performance with less expensive sound equipment. (A lot of pro audio contractors, installers and equipment manufacturers don’t like hearing this.)  Higher ceiling permits better gain before feedback and it becomes easier to isolate drums and floor monitors. The performance of the sound system is much better too when that is coupled with a good quality acoustical management system.

There are economic advantages too.  The higher the ceiling, the cheaper it is to heat and cool when using a vertical displacement HVAC type system which is specifically designed for large gathering spaces for people.  Such systems cost less to install, they use smaller HVAC components and cost about 30 to 40% less to operate annually.  In addition, the cooling systems last 2 to 3 times longer before needing to be replaced. In a way, building higher cost less both in cost and in operation over time.

Another thing to consider. If building new, don’t build a flat ceiling that is parallel to the floor. (and it doesn’t count of you put in a sloping floor.)  Many churches that are moving into commercial buildings are learning the hard way that flat ceilings limit the quality of live musical performances and congregational singing.  Sure, there are acoustical panels that can slightly improve the room for amplified sound, but the cost doesn’t justify the returns.  There is little that can help congregational singing even if you have the height. Vertical standing waves are harder to manage than a horizontal standing wave. If you know what you are doing, horizontal standing waves can be controlled to create an outstanding room.  It is part of the formula for that perfect worship space.  Funny though, most concert musicians that perform in a church that I have fixed, they often make comments like, “I wish our concert hall sounded and performed as well.”  That is almost like saying, “concert halls make for lousy worship space but worship spaces can perform better than a concert hall.”

Finally, there is the Biblical standard for church sound.  For a 160 seat church as detailed in the Bible, the Biblical standard is the width of the room is to be 50% of the length and the height of the room should be 75% of the length.  However, we now know that anything over 45 feet high and less than 2000 seating, the extra height is not needed.  It is the length to width ratio of 2:1 is key and a constant height of 45 feet or 13.7 meters.  For those who don’t want long rooms, because of sound systems, we can use a length of width ratio of 2:1.7 or a room that is 100 x 70, and you must always use the room lengthways or you destroy congregational singing and speech.

God gave us the laws of physics for a reason.  When we obey God, we reap the benefits.  When we ignore God’s teaching, you will have your reward here on earth.  The sanctuary of a church is a battlefield where the hearts, minds, and souls of people can be adding or subtracting people from the Kingdom of God.  The acoustics of a church plays an important part in either adding or subtracting people.  The change is slow and often not noticed, but when you visit hundreds of churches that have their worship spaces upgraded to the standards of the Bible as best as possible, there have always been an increase years later, ( unless there have been leadership or church split issues.)

If you can, to get a better picture of planning a new church, read this article on the Authority of God in Modern Church design.

*Note* In most countries that have freedom of religion laws, the worship space portion of a church building has no roof heights limits regardless of local city building height restrictions. 

**Note** The data is based on 1200 churches from around the world.

Where are the Carboard Tubes

Posted by jdbsound on August 28, 2017

Churches use a lot of Cardboard Tubes in acoustical room fixes because they are very effective in getting the room performance they want and need.  Cardboard Tube not only outperform all other acoustical products in churches but they are also the most affordable.  There is nothing that can do what half-round tubes can do, even at 40 times the cost.

Ok then, what if you don’t like the look of cardboard tubes around your worship space.  Here is an option some churches have been willing to spend a little extra for.

image10

These look like standard 5 inch deep absorbing panels.  They are not.  These are Sono Tubes mounted in a wooden frame and covered with cloth.

The cloth was an added expense and it was worth it.  The fire rated cloth is expensive and before covering the panels, you want to make sure the acoustical system is going to work and work it did.  The church is very happy with the results and they are enjoying the room.

image8

This is what the installation looked like before it was covered.  The wooden frame has no effect on the performance of the half round tubes.  The cloth only affects frequencies above 10,000 Hertz which means they have no effect on speech or music.  In this installation, three sizes of tubes were used.

At the bottom is a huge video wall screen.  On the wall are the Sono Tubes.  Yes, the tubes will work behind a vinyl screen.  If you notice the pattern of the diffusers on the wall. that pattern was needed to control lower mids and bass sound energy.  This pattern was pretested in our test room.

Here is the finished installation of the video system.  It takes three projectors for each screen.  The center screen is a video wall.

Are Churches growing or shrinking?

Posted by jdbsound on March 23, 2015

Being in the church sound and acoustics business for over 33 years, you get around enough to see firsthand if the church community is growing or shrinking.  After all, when all of your income comes from providing a service exclusive to the church community, you would want to know if your services will become obsolete or not.

The question stands, is the church community growing or shrinking?  The short answer is – – – – the church community is growing and church attendance is growing.  Churches for the last 100 years have been growing on average about 10 to 14% every year.  That is the good news.  Unfortunately, that 10% growth annually is not the same as 10% of the population.

It seems that sometime around the mid 1970s the population started to grow in North America (and the rest of the world for that matter,) at a fast rate than what the church was growing.  In order for the church to grow at the same rate as the rest of the world, the church would have had to grow up to 25% annually.  So while the number of Christians in relationship to the total population is declining, the church continues to keep growing.

What also makes it harder to keep track of church growth is the number of breakaway churches that leave the umbrella of the denominations where church growth is not often recorded to any national data base.  In my work, I get to see both denominational churches and independent churches.  At the end of the day, it seems that there isn’t much differences between them.

Many people who were part of denominational churches often leave to get away from the institutional, the bureaucracy, the rules, the regulations and static growth burdened by years of complacency.  The problems I am hearing from people who have been going to these larger “growing independent churches” is that after a while, they complain about the same institutional, bureaucracy, rules, regulations and push for more growth burdened by years of complacency.  The difference is that they are inside the same bureaucracy that they left years ago and often don’t realize that they are now the cause of why people are leaving the independent churches are starting unsupported breakaway churches.  Who is keeping track of those numbers?

Then there are the non-registered home churches that are out there. There are thousands of them that average about 12 people each.  Who knows how many of these groups are there but, at the end of the day, overall statistics pegs church growth at 10 to 14%.  That is good news.  Will the “church” ever be more that 10% of the population again?  Most likely not.
