    Churches are the most complicated spaces to tame. There are no short cuts to church sound. The information presented here just scratches the surface of how large rooms have layers of sound that creates either constructive or destructive reflections and energy management. Most of the information here is based on years of experience and thousands of hours studying, research and testing. Every church can have great acoustics and worship experience. Knowledge has taught us that whenever aesthetics is chosen over performance, the congregation loses out. Whenever worship space performance outweighs the aesthetics, everyone benefits.

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.

Tillsonburg Alliance Church

Posted by jdbsound on December 3, 2019

Tillsonburg Alliance Church has completed an acoustical upgrade. Improvements include better congregational singing, less feedback in the sound system, easier to get a high quality mix for praise and worship, and when there was a power failure on a Sunday morning, as the pastor preached, everyone was able to hear just fine.

The layout of the acoustical treatment was created by church members who wanted to make the stage area unique. Designing such patterns are possible without giving up on performance. If you look at the longer diffusers, in this case, they are closer together to make up for the smaller diffusers that create a unique visual experience. The results says it all.

God is Not an Option in Church

Posted by jdbsound on August 14, 2019

God gave us the Laws of Physics.
They have to be obeyed if what you are building will work properly.
Ignoring such laws damages the results or it can lead to a disaster.
These same laws have to be obeyed when it comes to church acoustics and church sound systems.

God laid out the Laws of Physics in the Bible for the best acoustics a temple/church/synagogue can have.
These laws have been given to us for the best worship experience possible for singing, hearing speech and for music.
These Laws have been with us for over 3000 years.
When are churches going to start following them?

If you believe that the Bible is sufficient in all things, then all churches have everything to gain when they apply God’s way to manage sound in houses of worship dedicated to God.

Does Your Church Need help with Sound?

Posted by jdbsound on August 1, 2019

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

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

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

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

The Scientific Foreknowledge the Bible Teaches about Church Sound?

Posted by jdbsound on July 26, 2019

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

Introduction

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

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

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

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

Thank you.

Seeking the Truth

Posted by jdbsound on July 18, 2019

As an expert in Church Acoustics and in the pursuit of the truth, I have also been passionate about finding ways for all churches to afford an acoustical solution that will solve just about every sound problem most churches run into. What can be more exciting than knowing that the cheapest and best acoustical solution in the world for all churches comes from the book that all Christians follow and obey – the Bible. When a church uses the Bible’s method for acoustical management, sound problems almost all go away and in most cases, a sustained higher church attendance happens after around 18 months. God is the author of Church Acoustics and it is time for churches to seek God first for answers and God will reveal His way to solve sound problems in His Houses of Worship. Whenever a church is dedicated to God, doesn’t it become His House?

Joh_14:6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me. If we take that a step further, Jesus was present in the design of Solomon’s Temple. While Millions have already been saved in the past, present and hopefully the future, how many more can be added if all Houses of Worship were built or brought up to the same acoustical standards as in Solomon’s Temple? Since most churches don’t have that quality of room acoustics, I guess we may never know!

Watering Down the Gospel

Posted by jdbsound on July 8, 2019

Years ago, someone wrote these two sentences to make a point about the quality of sound.

How to wreck a nice beach?

How to recognize speech?

In many churches, when these one of these two lines are spoken over the sound system quickly, regardless if they are using a headset mic, lapel or lectern mic, most people guess wrong when these two line are projected onto a screen.  You can have the best pastor around but if the acoustics are not up to Solomon’s Temple quality, the room could be watering down the message more than what many may believe.  The priority for sound in a house of God should always be quality of sound over quantity of sound.

1 + 1 = 3 or When is Doubling the Power, not +3dB?

Posted by jdbsound on June 17, 2019

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.)

Outdoors, sound follows the basic rules of physics.

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. 

Indoors, sound is confronted with many other rules of physics which changes how the first rule works.

Here are the most common reasons for the sound failing to increase 3dB when doubling the power or speakers.

  • Standing waves
  • Dimensions of the room
  • Too much-stored energy in the corners
  • Too much high-frequency absorption

Standing Waves

Standing waves are excessive amounts of energy between parallel walls within a confined space.  It can often hear it.  To listen to it in a rectangle room, go between the parallels walls that are the closest together. Often it is the side 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 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 standing waves are the cause of it.  The standing waves are 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 people from hearing the clapping returning from the back of the room. Standing waves have the effect of isolating everyone from each other in the room.  This result is also why the drummer seems to sound so loud and why most drummers strike the drums harder than they have too. It is because they can’t hear their drums at a lower level.  This outcome is also why many people comment that they can’t hear themselves when singing, and it makes them feel alone in a room full of people.

Any church with parallel walls will have standing waves if there is nothing to manage them

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.

The dimensions of the room

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.

Too much-stored energy in the corners

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. 

When the front of a church is in the corner, everything is either 18dB louder or 18dB quieter when compared with churches that have the front on an end wall.

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.

Too much high-frequency absorption

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. 

For most churches, carpeted floors and padded seating is all the absorption needed. When this much absorption is add, the congregational singing is very dull and people have to be super motivated to see more that 20% of the audience singing.

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.

Ten years later Kingston Rd United Church

Posted by jdbsound on May 29, 2019

Kingston Road United Church had sound issues. They tried several sound system designs with no real success. Someone suggested JdB Sound Acoustics.  When I arrived, an elderly lady came to me and said, “If you can’t fix this room, then this church will not be around much longer.” Somehow, several people on the sound committee believed that if the church sounded better, they stood a better chance at keeping the doors open.

In 2008, I was hired to fix the room. I designed for them an acoustical and sound system solution. The sound system was completely replaced. The acoustics plan was using half-round tubes on all of the walls. The results were as several people put it – Amazing. Before, you could not understand anyone talking more than 15 feet away. After, you could talk end to end of the 120 ft — long worship space. The church seats 550 people.

Today in 2019, the church is thriving. It has become a place for concerts, drama and singing events. The church is growing in a location where there is only one parking spot. Church attendance may still be low, however it is higher than in 2009 and with all of the other activities, it has been more than enough to keep the doors open. Acoustics alone didn’t keep the church from closing, but it became a tool to attract new members and other forms of income for an inner city church. Good acoustics seemed to inspire the church leadership to have confidence in knowing that if people could have a good hearing experience, the greetings they would receive from the members would be that much better.  There is also proof that good sound means a greater chance for people to return.

A few years back. Cinemacoustic Solutions Int’l, Harrisburg, Pennsylvania, did an experiment with two theatre test rooms. Both rooms were identical the same visually with one room properly treated acoustically, and the other was not. Room “A” was treated properly; however, Room “B” was not treated at all.

Here is a summary of the results.

“Funny enough, while many of the students made comments about the sound, stating they thought the speakers in room “A” sounded a little better than those in “B”, nearly all of them said, “the picture in Room “A” was far better than that of Room “B”. The properly treated room allowed them to see & hear content at a caliber they may not have ever experienced before, to which they naturally attributed to better equipment, as opposed to the acoustical treatment of any sort. The properly treated space relaxed their senses allowing them to enjoy the environment and what they were doing as opposed to subconsciously concentrating on what they needed to do to better enjoy their surroundings.

The same subconscious energy applies to an orator speaking in an untreated room vs. a treated room. Even a boardroom with executives around tabling important and perhaps complex company matters, they can concentrate better when not “fighting” bad room acoustics while conversing or passionately presenting their opinions, vying for votes. They would never attribute the lack of ability to concentrate on poor acoustics because they simply wouldn’t know to do so, however it can very well be a culprit.”

Good church acoustics matters. Kingston Road United Church is a fine example of how acoustics made their worship space a place where people want to do activities with speech and music. A place where people want to be and where hearing the Gospel is better understood. At Kingston, you spend more time understanding what was being said rather than spending all of your time deciding what words were being said or just trying to hear.

Really Useful Charts and Helps

Posted by jdbsound on May 20, 2019

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 minimum heights. Building new churches with lower ceiling heights degrades speech, congregational singing, cost more to heat, cool and maintain.
