    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.

Natural Acoustical Amplifiers

Posted by jdbsound on May 22, 2012


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:

Armeanian Pentecotal Church Montreal

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
