Who gets the final say in Church Aesthetics? The Architect or the Acoustician?
My opinion suggests that if the Architect is able to provide a space with the right acoustical performance, then they get the final say. If they fail to design a complete worship space that meets the churches needs acoustical for the life time of the church building, people like me get the final say in how a church looks. (I don’t think many Architects like this and this is why they don’t like hiring me.) Instead some churches are hiring me instead of Architects for their worship space and HVAC designs. My services cost less and hiring the Architect for just the engineering and exterior finish of the church (which the community sees every day) costs way less too.

Kingston Road United Church.
Location: Kingston Road, Toronto, Ontario Canada
Consulting Date March 2008
Completion Date by Church members – October 2008
Sound System installed by Westbury Sound – December 2008
- Seating capacity 500+
- Ceiling over 40 ft high
- Over 120 Cardboard Tubes custom made order and placed around the room in 8″ 12″ and 16″ half rounds.
- Between 120 to 800 hertz removed 18 to 22dB of excess energy.
- This change allowed a single speaker system to cover a whole room 134 ft long.
- Throw distances from speakers to back wall, 98 ft.
- Contractor who installed the system was surprised at how well this sound system worked and how much the room changed.
- Contractor suggested delayed speakers before the acoustical treatment was done.

Windows inside of a worship area can be an acoustical hazard. Standing waves, echoes and bass problems are just a few of the ways large windows in a worship area create problems. Turning plain ordinary expensive windows into high performance acoustical windows is brilliant and they cost less. It does require more advance planning.
In this example the windows provide and added benefit. Now there is fixed seating in the foyer – a minor detail many churches leave out – considering the amount of time some people like to fellowship in a church foyer.

I’m away next week to Thunder Bay. If anyone want’s to meet up with me while there, send me an email, I will tell you where I am working and you can join me or visit. The church I am working on has some unique features that will require a very different solution than what you would normally see me do.
To contact me, send you email to jdb@jdbsound.com and I will fill you in on the details.

Is a New Church or existing Church complete after it opens for worship or after it has the proper acoustics installed?

When standing at the pulpit at your church and the sound system is off, do you speaker louder or quieter?
When you turn the sound system on, do you speak just as loud or quieter?
If you answer quieter to either of these two questions, you most likely have a major acoustical problem. Why?

Walls are amplifiers of sound.
Outdoors – when you double the energy with amplifiers or speakers the sound levels increases 3dB.
Indoors – when you double the energy with amplifiers or speakers the sound level of certain frequencies can increase up to 9dB or cancel the sound 100%.
Example Below:
Before acoustical treatment, there would be 1dB loss at 10 ft and 2dB loss at 40 ft. without the sound system.
After acoustical treatment, there is 4dB loss at 10ft and 8dB loss at 40 ft. without the sound system. Also, intelligibility changed from 79% at 40 ft to 92% after acoustical changes. When you add the sound system the coverage with +/-3dB
This was in the middle of the acoustical transformation

The ear can hear distortion before it shows up on the meters of most mixers including studio and digital mixers. When the room acoustics are good, you can hear the distortion up to 6dB sooner than what the meters show.
