The Bible is the de facto standard for all church worship needs including sound and acoustics.
2 Timothy 2:15

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

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.

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.

Here is a simple test anyone can do to determine the acoustical condition of a church. Physics says that when the power* is doubled or when doubling the number of speakers, the sound level will increase 3dB. This result is real when outdoors. This outcome can be false indoors. When it is false indoors, it is because there are acoustical problems. Please notice that it is problems, not a problem. When adding a second speaker failing to increase the sound 3dB, this test shows that it is never a single acoustical issue. It is not a sound system problem. The sound system is exposing the root problem. (If the second speaker is wired out of phase, the sound will decrease in level.)
When outdoors, if there are two loudspeaker playing with the same volume of pink noise side by side or up to 6 feet apart, and set up a test microphone or SPL meter 30 feet away. (An iPad or phone with testing software can be used if it is calibrated.) When the second speaker is turned on or off, the sound level will change 3dB. This result is constant in physics. The reason this is always true is that there are no barriers around to limit the sounds from spreading out or returning from a reflection that can interfere with the direct sound.
When indoors, depending on the size of the room, often this is not true. This failure is noticed the most with Subs and sound energy below 500 Hertz. Doing the same test at 30 feet inside of a church, the sound level change is often 1, 1.5, or 2dB. If the result is 3dB, there are either a lot of open windows, lots of doors that are open, the church has more than 3000 seating or the church has great acoustics.
Here are the most common reasons for the sound failing to increase 3dB when doubling the power or speakers.
Standing waves are excessive amounts of energy between parallel walls within a confined space. The effect of standing waves are not always apparent. Standing waves are usually excess mid and bass frequencies of energy that masks the highs. You can’t hear a standing wave but you can hear the effects of it. To identify if your church has standing waves, go between any parallels walls. Stand about 4 feet from one of the side walls. Make a loud, sharp noise like a hand clap once. If a person hears any rapid pinging sounds, this is a sign of the presence of standing waves. The sound heard is often a higher range of frequencies, and they usually called flutter echoes. Flutter echoes are a symptom of standing waves. Bass sounds, which have longer wavelengths can’t produce the same volume of sound to hear as a flutter between parallel walls. Whenever a person hears flutter echoes, excess bass energy present too. This result is also true for all other room shapes when flutter echoes or flutters from a simple hand clap occur
A second clue to standing waves is when standing at a pulpit or where a minister preaches from. With a hand clap, if the reflected sounds are coming from the side walls or behind you, the standing waves are the cause of it. The standing waves are masking the highs, creating the effect as if it is preventing a large portion of the sound from reaching the other side of the room, and what is reflected back is being canceled out by the standing waves a second time which in turn prevents you from hearing the returning clap. Standing waves have other detrimental effects too. It has the effect of isolating everyone from each other in the room. This result is also why the drums seems to sound so loud and yet, this is also why most drummers strike the drums harder than they have too. It is because they can’t tell how loud they are playing at any volume level. This outcome is also why many people sitting in the pews comment that they can’t hear themselves when singing, and it makes them feel alone in a room full of people. This is the number one cause of people being discouraged from singing.
The reason the sound doesn’t increase 3dB when adding a second loudspeaker is because of the excess bass energy created by the standing waves in the worship space. The excess air pressure is like putting a finger lightly on the woofer. The excess air pressure acts as an acoustical load on the woofer, and that dampens the amount of sound coming from the loudspeaker.
Standing waves can only be removed with diffusion or some form of sound scattering.
If people try to use absorption to fix this problem, while it will remove the flutter or in some cases, shift the flutters to a lower frequency, the untreated bass energy will make the standing wave problem more pronounced. It will increase the feeling loneliness and discourage the congregation from singing even more.
In churches with low ceilings or seating less than 200 people, the room is too small to be free from surface related sound inference reflections. In a larger church space with a flat ceiling less than 16 feet high, the room will have standing waves floor to ceiling which limits the ability to increase sound 3dB with just doubling the speakers.
The reason the sound doesn’t increase 3dB when adding a second loudspeaker is that the room is limiting how much the space can support. The excess air pressure from the extra speaker is like putting a finger lightly on the woofer. The excess air pressure acts as an acoustical load on the woofer, and that dampens the amount of sound coming from the loudspeaker.
The only option is to diffuse all of the room if a small church. If a low ceiling, diffusers will have to be added to the ceiling. Acoustical tiles and drop ceilings cannot correct this issue.
Another principal of physic is how sound is affected by boundaries. A loudspeaker on a 10-foot pole measures 60dB. We call that free space. When we put the speaker on the ground, the speaker will be 6dB louder. That is referred to as “half space.” When we add a wall and the floor, we call that “1/4er space” and the sound increases 12dB or doubles in loudness. When we add a second wall to the floor and create a corner, that is “1/8th space,” and the sound rises 18dB.
Corners collect the air pressure that is created by longer wavelength sounds that accumulate on the flat surface of the wall. With nothing to direct the sound, the sound pressure moves in all directions. Eventually, the excess bass energy makes its way to the corners. Depending on a lot of variables, the amount of energy that builds up is often too much. Churches will low ceilings, large flat walls, or flat ceilings tend to have too much excess bass in the corners. All other church shapes, except for domes have varying levels of corner issues if not managed. Excess corn energy has a similar effect as standing waves. When there is too much bass, it masks the highs. This, in turn, creates hotspots and coldspots throughout the room. Hotspots and Coldspots are frequency dependent. If the sound level changes are of a narrow range of frequencies, it was most likely found them with instruments. When a person notices them with their ears, it means anyone with a hearing problem will miss out on some of what is being said, or what they heard and what was said was different.
The reason the sound doesn’t increase 3dB when adding a second loudspeaker is because of the excess bass energy created by the bare walls in the worship space. The excess air pressure is like putting a finger lightly on the woofer. The excess air pressure acts as an acoustical load on the woofer, and that dampens the amount of sound coming from the loudspeaker.
Keeping excess sound out of the corners is best done with diffusion. It cannot be done with absorption unless the absorbers are as thick as the wavelength of the sound waves.
Sound arrives at our ears as air pressure vibrating at a rapid rate. The faster the air vibrates, the higher the sound pitch. The slower the sound vibrates, the lower the pitch. The vibrations are referred to as Hertz. Sound travel at 1130 feet per second. At 100 Hertz, a bass sound has the wavelength of just over 11.3 feet. At 1,000 Hertz the sound waves are 1.13 feet, and at 10,000 Hertz the sound waves are 0.11 feet or 1.3 inches.
When there is too much absorption in the room, what is left is too much bass. The excess bass masks the highs.
The reason the sound doesn’t increase 3dB when adding a second loudspeaker is because of the excess bass energy created by too much absorption. The excess air pressure is like putting a finger lightly on the woofer. The excess air pressure acts as an acoustical load on the woofer, and that dampens the amount of sound coming from the loudspeaker.
The fix for such a problem is by removing the right amount of absorption panels and replace them with diffusers. Then complete the room by adding more diffusion throughout the sanctuary to correct the frequency response of the room.
These four issues are never a singular issue. They are often in combinations or can include all four. Along with these problems, there are often reverberation issues, echoes, excess late reflections, the poor frequency response of the room, and other room problems that have little to do with this simple 3dB test, but they are usually there as well. These problems can be heard when a person learns what to listen for. Looking at how sound system is equalized is another clue of room problems. The issues have the result of the high numbers of the congregation not singing. (In a church with good acoustics, they will often have more than 80% of the congregation singing every they are familiar with.)
Getting two loudspeakers and doing this test is simple and easy to do. If the sound doesn’t increase 3dB, this means that adding more subs or more speakers into a worship space will not get the expected outcome. For example. If the goal is to increase the bass in a worship space 3dB, and sound system has only one subwoofer, do this test, If the bass increased only 1.5dB with the second box, then it will take two more speakers just to get a 3dB increase for a total of 4 boxes. Think of the cost of adding three speaker boxes and all of the related hardware required to support that. An alternative would be to fix the room with diffusion, the gain will be 6 to 10dB of performance without doing anything to the sound system. It would be equal to adding 8 or 16 subwoofers depending on other acoustical or architectural considerations.
Science is amazing when appropriately used to provide real solutions. Pseudo-Science or fake data is often used under the disguise of science and can be used to lead churches to false conclusions. Many experts in audio and acoustics who see the same data, know these problems are present. If they are not being addressed, it is because they lack the experience in knowing how to solves such issues. If a person has done this test and the sound system provider or acoustical expert is not addressing these issue, they are not qualified for correcting sound problems in a church. It’s like asking a Doctor who specializes in kidney problems to do Brain Surgery. What is needed a Brain Surgeon who knows how to fix both the acoustics and to design a proper sound system.
Get the church correctly evaluated before investing in that next sound system. It can save those responsible a lot of disappointments down the road. Fixing a room can cost less than replacing a sound system, or it could mean reducing the size of the suggested new sound system.
* Doubling the power required calibrated volume controls or switches to set up correctly as a viable test.

This is a chart that gives you wavelengths of sound for all frequencies, speech, and music ranges
This is a Church Height chart. These are the minimum heights. Building new churches with lower ceiling heights degrade speech and congregational singing, and costs more to heat, cool, and maintain.
This chart shows the difference between the absorption rate versus decibels. For example, something that is rated as a coefficient value 0.5 is equal to 3dB of sound absorption.

The goal of any worship space and the church sound system is not about loudness, gain before feedback, intelligibility, special sound effects for the organ or choir, having the most talented performers in the worship team, how many wireless mics, number of channels the mixer has or the name brand of equipment you have. The goal of a church worship space and the sound system is to be a safe place where the Gospel can be presented clearly and with little to no blemishes. Where every person within the worship space can hear and understand the Gospel as clearly as when having a conversation with someone only 4 feet away and sharing the Gospel. Anything less than that goal means that the spoken word can be corrupted in the journey between the minister’s mouth and ears of all those who are listening. The Gospel needs to be broadcasted and understood as clearly as reading God’s written words.
If your church has hot spots, dead spots, good sound in these seats and poor sound in those seats, then the Gospel is not being presented equally to everyone. If your sound system has technical problems during worship often, then it is a distraction, and it can make the difference of understanding something important.
The chart below shows tangible results when your worship and sound system are tested. There should be three tests.
The first is with a test speaker. It is a point source speaker that is small enough to mimic a person’s voice.
The next test is feeding a signal directly into the sound system and test those results. This test is just about the playback quality of your sound system.
The third test is to use the test speaker 30 inches from an open microphone such as a pulpit or any microphone on a stand and test the combined results of the worship space’s acoustics direct interaction of the sound system and open mics. You can also do a second version of this test and place the test speaker 4 inches from a microphone where the microphone is 45 degrees off axis.
If all three tests are not in the Yellow section, the results will let you know if it is your sound system, the acoustics or all of the above. This is also a better indication predicting if upgrading your sound system will improve the results you are looking for. This is also a strong indicator that your worship space needs some kind of an acoustical management system
You can get your church tested. It doesn’t cost much, and the results can save a life or many lives, depending on your point of view. As an independent consulting company, we offer church testing and results with no obligation to use our services in the future.

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.
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.
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.

There are dozens of acoustical spreadsheets that come with the promise of a viable acoustical fix. Some sheets are for studios and some are for home theatres. There are also other spreadsheets for larger rooms. As rooms get larger, (as in Christian Churches and worship centers) those spreadsheets become less accurate. Sure, the better spreadsheets adds more variable to compensate for the limitations, but the limitations are still there. Furthermore, with all of the spreadsheets, you have to add an additional line to include a fudge factor. In some spreadsheets you need to add multiple fudge factor lines.
When a person tries to use an acoustical spreadsheet, they are only looking at one parameter of the rooms acoustics. You are only looking at “time.” The problem is, for churches, and I MEAN ALL ROOMS WHERE MORE THAN 150 PEOPLE GATHER TO WORSHIP – there are other parameters that are equally or more important than “time.” Acoustical problems always come in layers. The minimum number of layers of acoustical sound management in a worship space is 4 layers. As a worship space becomes larger, the more layers you have to attend to. “Time” becomes only a fraction of the real acoustical problems you are faced with. Obviously you can’t see them but you can measure them if you are trained to recognize when you hear them.
The problem with spreadsheets is that they are not looking issues such as standing waves – and every church – regardless of shape has standing waves (unless the space is acoustically managed in the first place which also means this article is not for you.) Spreadsheets are not looking at excessive noise from early and late reflections. They are not looking at bass buildup often found in the corners of a room. They are not looking at flutter echoes and full syllable echoes. These are all sound effects than can’t be dialed out with equalizers, delays, algorithms and the next miracle digital gadget or software. (Yet that is how most sound system designers try to deal with room acoustics.)
Regardless of a persons acoustical training, knowledge or experience, a spreadsheet cannot tell you when standing waves are masking flutter echoes. A spreadsheet cannot tell you when bass build up is masking a standing wave issue. A spreadsheet can’t tell you how much the early and later reflections are reducing music and speech intelligibility.
All that a spreadsheet can tell you is how much “time” it takes for a sound to decay in a room either as an average number. Some spreadsheets are much more detailed and they have been written as an attempt to calculate a room in octaves or by 1/3rd octaves. If it was only that easy. Measuring and calculating time is just a sliver of the acoustical signature of a space people worship in.
It takes a lot of training to learn Church acoustics. The same applies to Studio Acoustics, Recital Halls, Concert halls and lecture halls. All of these rooms have specific acoustical needs and they all require a unique set of skills to properly fix them.
What makes a church so complicated is in how a church is used. When a church is designed as a “church,” it becomes the most multipurpose space there is because of all the ways a worship space is used. When you say you want the worship space to be more “Multi-Purpose” or more flexible in it use, you are actually limiting what a basic worship space is supposed to be able to do.
At the end of the day, an acoustical spreadsheet is only a small snapshot into church acoustics. It can’t help with congregational singing, it can’t help with a noisy stage for a praise and worship team or choir and it can’t help with drum issues or speech intelligibility.
What often happens is with the spreadsheet, it will guide you to a solution that is based on absorption. When an acoustical fix is based around absorption, you wind up “killing” the room for all music – especially contemporary music and congregational singing – and the masking effects of the other acoustical issues get worse. Sure, the room sounds more tame than it was before, but the ability to understand speech is either no better than before or it has gotten worse. Before you know it, everyone gets in ear monitors and all of the members of the worship team have to sign an insurance liability waver stating that they will not sue the church for any future health problems with hearing loss. Seriously, is that the kind of acoustical fix you want?
That is what you get when you turn to an acoustical solution based only on spreadsheet calculations. To top it all off, the results are not much better when using computer simulation software programs. Simulation programs only show you the results at one frequency at a time. The computer generated image may be 3D but the patterns they show are only one frequency at a time – even when it is averaged out. To see large room acoustics in a simulation, you need to be able to see the results in 4D. Hologram can’t show you 4D images. That ability hasn’t been invented yet. You need to be able to see sound in 4 dimensions because all sounds are complex. Every sound made on earth is a combination of wave lengths that are generated at the same time. Some parts of a sound are measured in feet and some in inches. There is no way to visually see 100 Hertz, which is 11 ft long, and 4000 Hertz which is 3.5 inches long, at the same time in the same place yet in real life, that is what is happening with sound. We all take sound for granted but the complexity of sound is extensive.
But doesn’t sound follow the rules of fluid dynamic and other laws of physics? Of course it does, but only when you examine one frequency at a time and that frequency is never a pure tone. It is always complex. The only place you can measure and see a pure tone is in a machine like an oscilloscope and the moment you launch that sound into the air, it becomes complex. Just as sound is complex, so are the acoustical fixes for churches.
This is one way to test an acoustical solution before you recommend it to a church. Have your own testing facility. Whatever research is done in this room, it mathematical translates perfectly when it is scaled up into a larger space.
As a mantra, remember this: for all Christian churches, acoustical problems come in layers and whatever fix you choose, it has to address all of the layers in one step – which is possible if you want an affordable fix. There are many tools in the Acousticians Tool Box to fix a worship space. There are diffusers, resonators, traps and other devices that can address the needs of a church’s acoustics. There are also stand-alone electronic solutions that work in certain worship spaces. You need a lot of training to know which ones you need, what combinations you need and how to use them, and the last place you want to do your training and experimenting is on your customers.
If you are doing Church Acoustics or trying to fix your own church, don’t do it as an experiment and you know it will be an experiment the moment someone in your committee say something like, “lets try this as see what happens.” With those words, the acoustical solution is already doomed. Experts like myself can tell you the results the second you decide to try something and long before you apply the materials.
History shows that after a church spends it’s money on a thing such as acoustics, it will not be able to afford to fix any mistakes for decades. If the results makes the room worse or no better than before, then you are subjecting the church members to more sound abuse for years to come and we don’t want that. Spreadsheets don’t fix churches, good training and expert help does. (It’s also cheaper in the end to get expert help.)
Finally, consider this. The internet has become a treasure trove of knowledge. That knowledge is often presented as expert information offering sure fire solutions. I scan the internet often to see what is out there. There is a lot of great information and there are a lot of myths. When you collect all of that info, it only holds a fraction of the total knowledge about church acoustics. If we were to put a percentage on it, the internet holds about 2% of the total knowledge there is for church acoustics. The books hold another 8% of what there is to know about church acoustics. Church acoustics is so complicated that often, a seasoned acoustical expert like myself will have to fix one of a kind acoustical fixes often. Those unique fixes are often not shared because others may think that the one of a kind fix would be needed in every other church that has the same problem. You can have 10 churches with the same acoustical problem but in every one the fix has to be modified because of the other variables that have to be included. The rest of the knowledge about church acoustics is held by experts because the church community hasn’t taken ownership of that knowledge yet and there is no system in place for churches to share their experiences in order to avoid mistakes in the future. What is missing is the wisdom in knowing what acoustical fixes will enhance worship verse what acoustical fixes exchanges one set of problems for another set of problems. Problems which holds back and undermines the real worship experience the church leaders want you to participate in.
All church can have great acoustics and sound. If each church denomination or independent church were to set-up their own “Church Sound Standards” for the performance of their sound systems and worships space acoustics, churches will become the kind of places where people want to go. Once a standard is set, every church will have a Worship everyone can enjoy and appreciate.

Welcome to the world of Church Acoustics & Sound Systems
