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!

This is what a Phase Coherent Sound Diffuser System looks like. There is no other acoustical system that can perform as well as this. This is a system. Not a point-and-shoot system as how all other acoustic products are applied.

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 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 the song leader asked everyone to sing acapella during their first worship service.  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 managed their sound according to what the Bible teaches.  Sound in a worship space managed any other way comes up short of meeting the needs of any congregation. 

Here are more images of the church.

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.

Passive versus Active Worship. Is there a difference?

Posted by jdbsound on July 26, 2021


Introduction

Within the Church community, when someone speaks of worship styles, they will often refer to one of these terms, Traditional, Contemporary, Blended, Liturgical, Pentecostal, and Charismatic.  These terms are not exclusive, but they are an accurate description of how worship is conducted.  When studying congregational singing, all churches fall into one of two groups: Active Worship or Passive Worship.  Active worship is defined as congregations that always have more than 50% of the people singing.  Passive worship is when less than 50% of the people are singing all the time.  In most churches, less than 30% of the congregation is singing all the songs.  This single observation is the most common link that is driving many churches to turn to an entertainment style of worship.  Let us look at why many churches are going in this direction.

Traditional Passive Worship

Under the Traditional, Contemporary, Blended, and Liturgical styles, there has always been a commitment to an active style of worship – meaning – that the congregation is expected and encouraged to sing.  In some houses of worship, they sing acapella, while other churches will have a person conducting with the traditional piano and organ.  Some will add a guitar and bass.  While the focus is on the people actively singing, even if only 20% of the congregation is singing, it is accepted.  For these churches, the musical instruments are downplayed, even though they unintentionally perform louder than the congregation.  For these churches, the focus is on the Gospel message within most hymns and songs they sing.  This leaves some people with the idea that worship is boring or lame.  Some think that this style of worship is old, outdated, and needs to be modernized.  For the churches that have tried to modernize, the level of active congregational singing has not changed, and the impact of attendance decline continues.

Contemporary Passive Worship

Under the Evangelical, Pentecostal, and Charismatic worship styles, we should include churches that also use the word “contemporary” in defining their worship.  For these churches, it doesn’t seem to matter if the congregation is singing or not. The service, being conducted by a music team or band, will have the sound levels of their performance dominating everything.  The worship leader will choreograph songs and some Bible verses to get more people in the mood to sing.  Words are projected onto a screen where some people just mouth the lyrics.  Others attempt to sing loud enough to try to hear themselves and hope they are making a joyful noise.  Regardless of how much effort is made to get the congregation singing, less than 30% of the people are actively singing.

Some Evangelical and Pentecostal churches fall under a conservative style of worship.  What makes these churches conservative is that everything is focused on the coming sermon.  For these churches, it can take up to 45 minutes to get to the sermon.  Between prayers, announcements, scripture reading, someone making a presentation in song or words, and 3 to 5 songs that take up 20 minutes for their worship, the emphasis is on Jesus, the Gospel, or a lesson the congregation needs to learn.  Attendance in these churches is often directly linked to the preaching skill of the pastor, regardless of if they are conservative in their messages or not. 

The New Age of Passive Worship

Churches that have heavily invested in technology and worship teams, come under two groups.  They are either part of the conservatively lead churches, where the sermon is the main event of the worship experience, or they are the hyper evangelicals, where the music portion of the worship service is 30-90 minutes long. Often the music is as long as or longer than the sermon. 

For a growing number of churches, there has been a dynamic shift in worship styles.  The transition is a style of worship where the visual experience is synchronized to music. Where lighting, video, and moving images are synchronized to amplified music.  Churches are adding motorized lights that can change colors and video walls to create an atmosphere ripe to deliberately stimulate the senses.  In this environment, the song leading is crafted to guide people into a manufactured, energetic form of worship.  Even if people are not singing, at least some are swaying to the music, and others are raising their hands.  For such churches, the music has become the event, not the teaching of the Gospel.  Furthermore, in such churches, the Gospel is hardly part of the message. 

Rather, it is a message that is mostly about what God can do for me and a strong focus on how I can become a better person.  These messages promote programs and steps, and when followed, the members are promised a better life.  The teaching is tithing, serving at a food bank, and helping people more, and the reward is a better self.  Just praying to God, the sinners’ prayer with a promise to do better, is a ministry of works, not salvation.  James 1:19-27 clearly explains how people are to Love God first.  After learning to love God and becoming dead to self, then a person is properly motivated to follow His laws (notice that it doesn’t say to obey them).  Christians are to be doers of the word.  Because we love God, we do what the Bible teaches.  Sadly, many ministers teach it the other way around.  Their message is, do the work for a spiritual experience to feel better.  Feeling better means being saved!  Right?  No!

There is nothing more deadly than a carefully crafted message of false hope and a message for a better life by doing things that include something holy, sacred, spiritual, and secret, and never knowing what true salvation is.  These are people who have never experienced being transformed by the Holy Spirit as Jesus had promised everyone who accepts Him as Lord, who is our sin sacrifice, and begin a new life as a born-again Christian.  When a person accepts Jesus as Lord, what changed?  The change was going from hating or being indifferent about God to loving God.  This is it.  A person who is Born again will have the Holy Spirit helping them to stay on the narrow path.  A person who thinks they are Born Again and continues a life of sinning without a second thought may not be saved at all.  This is the trap of false teaching and teachers.  The addictive entertainment style of feel-good music and messages is crafted to create a manufactured artificial spiritual experience found nowhere in the Bible.  Anyone promising a better life by following a recipe outside of the teaching of the scriptures is a wolf.  That includes teaching where scriptures are taken out of context to say whatever message the composer wants.

Passive Worship is turning into Secular Style Entertainment

How are so many ministers getting away with preaching such a distorted message?  Mostly through entertainment.  Going to a healing service is like being at the circus?  It often begins with a short pep talk and then music for thirty to ninety minutes long.  During that time, promises are being made and testimonies from people who are caught up in the hype, raising false hope to a feverish pitch.  They shout out repeatedly, “Your faith will set you free!” followed by, “You pray, and God will give you whatever you want!” Where in the Bible does it say that God is a servant to man?  Rather, true Christian disciples choose to serve God as an act of reciprocating love.  When people get stimulated enough, the focus on true Biblical teaching gets diverted with shrewd speech.  The message is focused on the “new golden calf,” on the promise of miraculous healing on demand.  Here is when the blinded follower will do almost anything to get what the fake healers are promising or selling.  It is common that during such an event, the collection plate is passed around more than once, and the first time is before the healing service begins. The second or third time is during the healings and then at the end of the service/show.  They talk the devoted followers into continuous tithing for a miracle.  The hidden message is that healings and miracles can be bought.  That money is the replacement image of God, but what they are really doing diminishing faith down to nothing more than a “faith healers’ lottery game.”  Faith and salvation is not a game that can be bargained with.

The Elephant in The Room

This carnival-like atmosphere over time has moved from healing services into an entire worship program that gets people engaged into the most important person in their lives – self.  This artificial entertainment style of worship has progressed into an alternative to confronting the elephant in the room, “room acoustics.” Room acoustics controls how many people will actively sing during congregational singing.  Who wants to sing in a room where hearing one own voice isn’t possible, nor the person nearby, no matter how much effort is made?  The unmanaged room creates the feeling of loneliness.  Sure, there are many times in almost every church where more than 50% of a congregation will sing a very familiar song, especially to celebrate an event. Such singing happens only a few times a year and, in most rooms, it sounds dull and forced.  There is no return on anyone’s effort to sing with other people.  For most churches out there, regardless of size or attendance, only 15% to 35% of the people sing 95% of the time.  With such low participation, no matter how good the song leader or worship teams are, getting people to engage in the worship singing becomes an effort of futility.  Out of desperation, people will do whatever will work. 

The church is not built on Programs

Many churches have chosen an entertainment style of worship to draw more people into the flock.  With enough technology, anyone with modest musical talent can create an energetic rock concert-like atmosphere to get people to be passively engaged, if not actively engaged.  The difference is people can be stimulated with sight and sound to trigger the senses to release those feel-good drugs the body naturally creates called dopamine and endorphins.  Music can move people to started tapping a foot or finger when hearing a familiar feel-good song.  Music stirs feelings when several songs are played back-to-back.  When the music changes or stops, it often leaves people wanting more. 

Music is often used to trigger the body to crave more.  When the high energy and emotional music stops, there must be an equally good emotional message to follow up to keep the dopamine and endorphins flowing.  What better attention-grabbing message than a message on self?  And what comes before the sermon and after the music?  Most churches pass the collection plate—what better time to get people to give than when they are all pumped up and engaged into a well-crafted program.  There are church leaders and pastors who have been trained in the art of knowing how to carefully manipulate people with music and feel-good messages. Those churches will hire professional musicians who have had some success in the concert music world to shape the beginning of a church service to hyper-stimulate people to get them addicted to participating in passive worship.  If this sounds like a seductive form of brain washing, rest assured, it is.

People are so pumped up, not realizing that even though they are surrounded by many people and enjoying this passive form of worshiping, deep down, many have this subtle and distressing feeling that they are still all alone.  The common thread in all these churches is acoustics.  The room physically cannot support congregational singing.  Everyone wants to sing but they give up because of how the room makes them feel.  Before worship starts in some churches, the young people are encouraged to put their hands up and sway to the music as they scatter throughout the audience.  When people see the youth doing this, it looks so spiritual.  That is when peer pressured sets in and more of the audience joins in to make the appearance, they are actively worshiping.  Watch any YouTube video where people are raising their hands in worship and it will be the youth, spread throughout the audience, raising their hands up first.  How artificial is that! 

Active Christian Worship

However, that is different than being in a worship space where the acoustics are so good; over 50-80% of the congregation sings without being self-conscious.  They are singing effortlessly, with complete freedom to express themselves as a coral of congregational singers expressing themselves, often with four-part harmonies. This is what active worship is like all the time.  When the acoustics of a church is good, it is easy to have enough people engaged in singing to the extent that there is no need for an entertainment style of worship to lead the congregation.  When the worship space properly supports congregational singing, people will also do a slight sway and raise their hands for many of the traditional and modern hymns.  These people do this spontaneously because they are free to comfortably show their love for God.  They don’t do this to make themselves feel good, but it does help to feel a sense of peace to show God love in a respectful way.  This is not about getting rid of worship teams, but where the job of the worship leading is reversed.  Where the worship team follows the congregational singing in a support role rather than leading and overpowering anyone who is singing, even if their joyful sound is just a whisper.  This is different than when music is used to manipulate the audience into hyper stimulation and feeling better about themselves. 

History on the Order of Worship

Another item that will be seen as controversial is the notion that music should follow the reading of scriptures and the teaching rather than before the sermon.  The Gospel message, when properly taught, is never a feel-good message, but rather, it is supposed to be about reinforcing our love for God as a community.  The message is about keeping the believers on the straight and narrow path.  It is about following God because we love Him, as He has always loved us.  It is about following His laws to be safe.  When Jesus ended the Sermon on the Mount, He didn’t end the lesson as a feel-good message.  When Jesus finished preaching from a boat in Matthew 13, that message also ended as a warning.  In preaching the Gospel properly, the end of most sermons will either be a warning or a lesson in how to be a follower of Christ.  There will be teaching on sin, repentance, and change.  There are no feel-good messages in the Gospel. 

And when should the scriptures be read?  Through Jesus’s own example in Luke 4:16 “And he came to Nazareth, where he had been brought up. And as was his custom, he went to the synagogue on the Sabbath day, and he stood up to read.” In most cases whenever the Pharisees or scribes confronted Jesus, He would answer with a scripture verse first, then a rebuke or teaching. 

Here is the dilemma, people get emotionally hyped with feel-good music at the beginning of the worship services, only to be brought down to earth by the end of the sermon.  The pastor closes with a 1- or 2-minute prayer.  Then out of consideration or desperation, the closing song is for blessing or to brighten things up.  There is no time for reflection or meditation on the sermon.  If anything, the song is more of a distraction than comfort.  It’s no wonder people hardly remember what the sermon was 10 minutes after worship.  The reality is, it takes several songs to lift people up, but with everyone already investing over an hour into the worship service, most people are not in the mood to be comforted by three to five more hymns or songs again.

As it was the practice until the 1800s, worship service in protestant churches began with the reading of a complete scripture passage of the Bible by an elder or someone who has rehearsed the passage, or a person who is talented at reading out loud to an audience, The passage or passages should reflect what the sermon will be about.  Next is the sermon; after that is a time of prayer to reflect on the sermon, and engage the congregation further, a short Q&A lasting 5 to 10 minutes to secure the understanding the minister taught everyone, then announcements.  Finally, 3 to 5 songs to lift people up as a group where their unison of singing strengthens them in the message they just heard, regardless of how hard or direct the teaching was.  Biblical singing is about celebration with God and His teaching.  The Sheep will flock to a full Gospel message while the goats will run.  In researching about church history, it wasn’t until the 1820s where worship music moved from the end of church service to the beginning.  This was done deliberately to get people excited for the following feel-good message.  Yes, even 200 years ago, getting a congregation to have more that 50% of the audience singing was a struggle and historically, congregational singing has always been an issue dating back to 4th century churches.

Bound in a False Spiritual Trap

Sure, there are some charismatic ministers who can start off with a feel-good message without music to get things started, but the reality is, without the music, people are not going to stay for an hour for a feel-good message unless the pastor is a guru at motivational speaking.  People who participate in extended music programs become hyper-stimulated. They become malleable in teaching and brainwashing the followers into- whatever cult or false teaching they want to bind their followers to.  The hidden message here is to divide and conquer.  Fill the building with goats, call it church and watch the sheep scatter.  Making the sheep feel like they are failures. 

Having people worshiping in a room where the wrong type of acoustics cannot support authentic congregational singing, and by having an entertainment style of worship, people are trapped into being happy and feeling alone at the same time.  The false hope is that in going to the church, the feeling of loneliness during worship is replaced with “works” by helping with random, well-advertised “community” feeding programs, community projects, staging drama and music concerts, small groups programs, volunteering, tithing, and a hope for a taste of a holy or spiritual experience.  The entertainment style of worship draws in people with good hearing, which is mostly younger people.  Older people are excluded, and without elders who are not brainwashed to hold the leader accountable, the person leading such a church can get away with running the church like a business and do whatever they want. There is nothing more contentious than a church full of young people without older people who can demand accountability when the leadership becomes questionable.  

For an entertainment style of worship, where lighting, video walls, online TV video cameras, a huge sound system, paid musicians, and drama performances are as good as shows people would see in Las Vegas, worship quality acoustics doesn’t matter.  The whole program is set up to entrap people, take their money in an artificial religious experience where people come and go like a revolving door.  None of this is from the Bible, but the Bible is hyphenated to create a false message, blinded by the heavy use of technology.  Sadly, those who leave such a church often want nothing to do with Christianity again. This cycle of keeping people from the message of salvation must end.

The Bible is the Source for Meaningful Church Growth

The proper type of room acoustics that supports congregational singing does not need any gimmicks.  It quickly becomes apparent as good worship spaces become distinguished between being drawn into a ministry of salvation and loving God, or an organization of false teaching and false hope.  The Bible is the source of everything we know about God.  The Bible is also the source for knowledge about the right type of church acoustics for modern church buildings.  When canvasing and testing churches, 95% of all existing church buildings in a giving community cannot support active worship?  This is a problem the whole church community is struggling with all over the world.  The churches that are trying their best to stay on the straight and narrow path Jesus taught are losing to churches that are filling buildings void of the message of salvation.  Entertainment is the new gospel, whether it be a seeker sensitive, purpose-driven, or a self-help preaching message.  Church acoustics that cannot support the kind of congregational singing that can unite people is the single common thread all these church buildings share, and it leaves the church vulnerable to false teaching and teachers.

The good news is that the Bible has a universal plan that can transform any existing church from passive worship to the right type of acoustics for active congregational singing and maximize speech clarity at the same time.  In studying the Bible for answers to the right type of worship acoustics, the scriptures say who designed such a system – Jesus – the author and finisher (John 1:3, 1 Chronicles 28:19, Hebrews 12:2).  Unmanaged acoustics is simply a noisy room and entertainment style of acoustics is where the room has no performance qualities for worship whatsoever.  It allows false teaching and teachers to hide in plain sight within the walls of a building where worship service looks more like a talent show to a false god, and the minister is playing the audience like the Pied Piper.

Other clues of false teaching are:  Are the people encouraged to bring a physical Bible to worship services?  Are most of the song’s choruses?  Are some of the choruses repeated more than three times?  Do the verses of the songs have true Biblical teaching or are they about creating warm and fuzzy feelings?  Are the song leaders swaying to the music back and forth with their eyes closed, looking like they are in a trance?  Are all the texts the minister uses conveniently posted on a large screen for a short time, not giving anyone time to look them up?  Does the minister read full passages of what they are teaching, or are they just quoting fragments of the scriptures, hoping no one will read their Bibles?  Does the sermon begin with reading a complete passage of scriptures, and start teaching from what was read, or does the speech begin with a story – often with the minister involved?  (2 Timothy 4:2-4, preach the word; be ready in season and out of season; reprove, rebuke, and exhort, with complete patience and teaching. For the time is coming when people will not endure sound teaching, but having itching ears they will accumulate for themselves teachers to suit their own passions, and will turn away from listening to the truth and wander off into myths.)  For those who follow such teachers, things don’t end well. 

Seriously, Acoustics can help fix the Church!

A church with good acoustics that can support proper congregational singing, in most cases, can expose the sheep from the goats and those wolves in sheep’s clothing sitting next to the sheep.  There are many people giving up on the church, as attendance seems to be declining. Fixing the acoustics of a church for better congregational singing is one way to fight back dwindling attendance that doesn’t involve innovative outreach programs or turning to an entertainment style of worship.  If anything, it helps the minister to feed the Lord’s sheep and to fulfill the promise; when Jesus said in John 10:25-29,  “I told you, and you do not believe. The works that I do in my Father’s name bear witness about me, but you do not believe because you are not among my sheep.  My sheep hear my voice, and I know them, and they follow me. I give them eternal life, and they will never perish, and no one will snatch them out of my hand. My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father’s hand.  I and the Father are one.” 

Church acoustics is a tool, much like hymnals, Bibles, pianos, organs, choirs, and sound systems.  Good acoustics can’t fix the health of a congregation, but a better worship space will expose false teachings and make the preaching of the Gospel easier.  Some churches are not prepared to see the congregation separate as in the sheep from the goats, for once the goats leave, where will the sheep come from?  Have faith that the Gospel message will bring the sheep back, and before long, the flock will grow with new sheep.  That is the true work of the Holy Spirit.

For the Record

From the firsthand experiences of many churches that have already upgraded their acoustics, the change begins with a healthier fellowship through congregational singing.  Active singing during worship can be the difference between following Christ and hearing the preaching of the whole Gospel message and worshiping in a place that divides the church community by not addressing the elephant in the room.  This may sound like a stretch, but after seeing hundreds of church buildings transformed and observing with following-up visits how acoustics directly contributes to a growing congregation, the impact is unmistakable.   If there is any good news here, it is a fact that in following the Bible for true acoustical change, any church can afford it, regardless of the size of the sanctuary.  The secular community can’t make that claim ever.

Those who have read this far and worship in a church building that doesn’t support active congregational singing, have some faith.  In Mat 17:19-20, “Then the disciples came to Jesus apart, and said, why could we not cast him (the demon) out?  And Jesus said to them, “Because of your unbelief. For truly I say to you, if you have faith like a grain of mustard seed, you shall say to this mountain, Move from here to there. And it shall move. And nothing shall be impossible to you.”” Making a difference is possible by letting those in leadership know that there is a Biblical way to bring real Christian worship back into the Church and start by attracting those distracted and wandering sheep who know His Voice back into the flock.  Then, have faith that the Gospel message will do the rest.  What happens after that is all about leadership and who is the head of the church.

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.
