Is Church Acoustics Easy?

Posted by jdbsound on December 23, 2019

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

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

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

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

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

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

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

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

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

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

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

Do you have an echo problem?  We have a fix for that!

Do you have a reverberation problem?  We have a fix for that too!

Are you struggling with your sound system?  We have a fix for that as well!

Having problems with your rectangle shaped church?  We have a solution for that!

Having problems with you round church?  We have a fix for that!

Having problems with you octagon church?  We know how to fix those too!

Having problems with your fan-shaped, oval-shaped or square church?  We have custom solutions just for you!

Are you not happy with your commercial warehouse, storefront or converted mall space church?  We know how to fix that!

Have you already fixed your acoustics 9 times before and your still not happy?

We can fix any church that is absent of any acoustical planning and treatment.

We can also diagnose and fix any church that has the wrong acoustical treatment to get it back on track.

We have never been to a church that we couldn’t fix but we have had churches that were not ready to make the needed changes to get what they desperately wanted.  Oh, did you know that acoustics has always been the deciding factor in the aesthetics in a house of worship whether the acoustics are good or bad.  God taught us that beginning with Solomon’s Temple. (1 kings 6:29 (NIV)On the walls all around the temple, in both the inner and outer rooms, he carved cherubim, palm trees and open flowers.  (Please read my article about Solomon’s Temple https://www.jdbsound.com/art/art570.html))

Churches are not temples but they are dedicated as worship centers and houses of learning.  For worship and learning, you need tools. One of those tools is acoustics. You need a system of managing the air between the teacher and listener for the best worship and learning experience.  While a sound system is also a tool it cannot manage the air. It relies on acoustics for it to work. The better the acoustics, the more effective a sound system is.  Without the right acoustics, what are you really hearing or understanding?

Message for Architects and New Church Buildings

Posted by jdbsound on February 19, 2015

It has been brought to my attention by a number of church members about who gets to decide the final aesthetics of worship space interiors.  Church members of some newly built churches which are less than one year old were pointing out to me that in the end, we acoustical designers get to ultimately decide the final aesthetics of a church – not the architect, no matter how much effort an Architect puts into the aesthetics of a worship space.   If this sounds familiar then check out my post in 2012 where I made a similar post.  This discussion comes up often.

It seems that when acoustics are included in the design stage of a worship space, the Architect has the last say on the rooms aesthetics – assuming the acoustical plans are not compromised later on.  When acoustics are left out of the design phase of planning a new church, it is people like me that get the final say in the room aesthetics. Whether it is while the building is being built or anytime later – even 200 years later, it is people such as myself that often make the final aesthetic changes that will last the life time of a church building. 

The good news is, is that when we are included in the design phase of a new church, often our acoustical designs blend into the architecture and it is often not seen or at least not seen as an acoustical add-on.  In fact, often our acoustical designs come off as the Architects design of the worship space and at times to the untrained person it looks like we had done nothing.   Where friction often comes up, is when after the design of the church has been completed and the church board has given the green light, that is when someone raises the issue of acoustics.  Often there are major acoustical issues as what is taught in Architectural schools is about concert hall acoustics, school auditorium acoustics and lecture room acoustics. 

Church acoustics is totally different and I don’t know of any place were “church acoustics” is taught.  This is often why bringing someone like me after a finished design is presented to a church where butting heads starts.  When there are glaring mistakes being made and we point them out, it often means major design changes which often cost money to change at this phase.  Once past the design phase, churches are rarely ready to pay for design changes that often means delaying the project which increases costs higher.  As a result acoustics is usually left until the church is finished.  But wait!  A church is not finished until the acoustics are done.

As stated before, it is people like me who get to decide the aesthetics of a church when acoustical design is left out.  This goes for new churches, storefront churches, churches moving into commercial buildings or are using commercial building designs and churches doing renovations.  If you are an architect, include us at the beginning of the design process and the aesthetics will be all about you.  Leave us out of the design process and no matter how beautiful a space you thought you designed, it will be people like me who get to decide it’s final finish and sometimes, what we do is not very flattering but when it sounds great, the less than pleasing acoustical treatment starts to look good.

If experiencing poor sound in church could be measured as pain and people are not complaining about it, it could be because they don’t consider taking 10 extra strength pain killers per worship service as overdosing.
