What costs more? Drum Booth or Fixing a Sanctuary?

Posted by jdbsound on June 10, 2020

What costs more?  Or, what will give you the most bang for the buck?  Did you know that for less than the cost of a fully enclosed drum booth, you can fix all of the acoustical issues of a typical sanctuary?

Here is a typical drum booth churches are buying.  This booth retails for $4,300.00 and is often on sale for $3,000.00 plus shipping.

Here are all of the sound problems the drum booth solved. Keeps the drums out of the mix and the people in the front of the church have less noise from the drum kit. The downside to all of this is that often, the drummer plays louder which leads to many getting tennis elbow, and hearing damage often occurs.  There is one extra cost to include.  Often drummers need headsets or floor monitors to hear everyone else on stage.  What is often overlooked is that churches should have the drummer sign a liability waiver that the drummer will not sue the church for premature hearing loss and permanent damage to their arms due to tennis elbow.  Drummers often have to play louder in order to hear themselves inside a drum booth or shield.

Here is an example of a modest church that decided to fix the worship space instead of getting a drum shield or booth.  The material costs including the paint were $1,000.00.  Three people over 3 Saturdays completed the installation.  If you look carefully at the photo below, six months later, and there is no drum booth around the drummer.  They don’t need one anymore.

The following is a list of the planned sound issues solved:

  1. No more standing waves
  2. No more deadspots or hotspots
  3. Eliminate flutter echoes often heard off the back walls on stage.
  4. No more excessive bass

Bonus fixes included and no extra cost:

  1. Better speech intelligibility
  2.  Increases the signal to noise ratio to 21dB throughout the room
  3. Most of the floor monitor spill was gone
  4. Less sound system distortion
  5. No more bass distortion
  6. Equalized the room to remove excess energy at 400 Hertz -20dB
  7. Went from 18 inches to 38 inches of before feedback,
  8. The room is +/- 1.5dB throughout the room
  9. Makes the room easier for the musicians to perform
  10. Improved sound for people with hearing aids
  11. Before about 15% of the congregation was singing, now its around 60% after 4 months
  12. The sound team is having an easier time mixing.
  13. No drum shield of any kind
  14. Drummers are playing quieter without being asked to.
  15. The drummer can hear everyone on stage with minimum floor monitor support
  16. The pastor is less fatigued after preaching
  17. No more sound complaints if the sound is too loud
  18. The sound system sounds so much better
  19. The bass from the sound system is much more dynamic
  20. The bass from the bass guitar is cleaner and not overpowering any of the other instruments

These are all of the comments various church members, musicians, and the sound team shared after the first 4 months of the acoustical changes.  All they were hoping for was less bass drowning out everyone on stage, to eliminate hotspots and deadspots in the audience area and on stage, and to stop the loud reflections off the back wall affecting the musicians and the pastor when preaching.  The diffusers gave them 23 improvements instead of just three of them.  There is no other custom or “off the shelf” acoustical system that can do all of that in one step unless you have unlimited cash at 30 times the cost.

Drum Shield or Fixing a worship space.  For the cost of a drum booth, you can fix a church up to 800 seating with some sweat equity.

Article Published in Church Sound Magazine

Posted by jdbsound on March 30, 2020

Late last year, Kevin Young, freelance music and tech writer, professional musician, and composer ask to write up a profile article on JdB Sound Acoustics.  After several interviews, he submitting the article to Church Sound Magazine which is part of Pro Sound Web.  Pro Sound Web has published a number of my projects over the years and they are a great resource for churches for all things about church sound, lighting, and AV.

The Father of Modern Day Acoustics, Wallace Sabine and Solomon’s Temple

Posted by jdbsound on February 5, 2020

Introduction

In the field of acoustics and sound, many have said that Wallace Clement Sabine is considered the father of modern-day architectural acoustics. His scientific work was not only the foundation for concert hall acoustics, but few are aware of how his work has impacted the church community around the world. According to several sources, he was raised in a protestant home, but as an adult belonged to no church and professed no religious faith, yet his work has impacted churches in ways even Wallace could not have imagined. Wallace’s work included figuring out a prediction model of how to apply absorption to tame a room. He also proved that the reverberation time alone is not enough in helping performance spaces with their sound needs. He laid down a foundation, showing that you need much more detailing and care to create suitable sounding spaces, not just for concert halls, but for full Christian worship too.

Shortly after his discoveries and successes, most acoustical experts, Architects, engineers, and audio experts have focused on one thing, the reverberation time of a room – ignoring much of his actual contributions to modern acoustics. When Wallace created the first equation to calculate how much absorption is needed, most people thought that this equation was something magical. It was almost as if a single number could solve all sound problems for concert halls and performance spaces. While such a numeric value is essential, it was a small part of a much larger picture. Sure, Wallace did devote a lot of his time to such studies. Unfortunately, the absorption calculation moved from being a small tool as part of a broader view of performance acoustics to becoming the only thing that mattered. This equation gained mythological-importance to the point that for many laypeople….

Once again we see science and the Bible in almost perfect harmony. Within science, there are many tools. For acoustics, there are specific tools. With the help of the Bible, it requires a set of tools that are unique to churches. For concert halls, recording studio’s and other entertainment venues, there are a set of tools for each one. Most of those tools do not apply to churches. When the tools of an acoustical consultant don’t use the Biblical tools exclusively, you will always get the acoustical performance of what those tools were based on. If you have only concert hall or studio or entertainment tools, then the results will not meet all of the needs of the church. If you use Biblical tools, you wind up with a House of Worship as the Christian community should have, but most churches don’t have a clue of what they are missing out.

Solomon’s Temple was very detailed in how it sounded. If you believe in the Trinity as I do, because of John 1:3 you know that Jesus design the temple that Solomon built. Without the acoustical planning in Solomon’s temple, the Levites would of had to have super natural powers to hear each other within the walls of the temple. There is no record of the Levites having such powers. What did they do to the temple to make it possible for people to hear in such are large space?

Here is something to consider. If Solomon’s temple is a myth, then the details of how the temple walls were completed should not have survived over history. After all, there is no record of the interior of Herod’s Temple other than some carving on the ceiling that Herod ordered which is not in the Bible. If someone says the Scriptures are not the inspired word of God, then the details of Solomon’s temple wouldn’t matter. But what happens when you apply the details of Solomon’s temple to an existing church? If it is a myth, nothing should happen. If it fixes a church, doesn’t that prove God, Jesus and the Holy Spirit? What does that mean if over 400 churches have applied such a system in faith, using the same methods from the Bible to make the acoustics of their churches as best as they can be?

The details of Solomon’s temple matters. Nothing in the Bible is about trivial nonsense. Everything in the Bible has a purposes and the details of Solomon’s Temple is a roadmap to fixing existing churches and it should be a template for new churches today now that we understand why such details were persevered for us in the scriptures today. How many more churches need to be convinced before it becomes a normal way to complete our houses of worship?

If anyone with normal hearing in a church has trouble understanding what is being said in God’s House of Worship, the Bible has the solution for that. And that solution is very affordable. Please enjoy the rest of the article.
