What does a Stone Mason and a Church Acoustics expert have in common?
http://www.jdbsound.com/art/stone%20mason%20gets%20passed%20over.pdf
Would you know if the best person to do a job was a person from your church or church community? What if that person was one of the most skilled persons in the world for that service? Would you know it and would you hire them? Would you rather hire someone who is worldly, charges huge fees, who give the best sales pitch over someone who is better skilled, who charge less because they want their work to be accessible to any church, not just churches who can afford the big buck and the hype? Is it possible for a Christian to be the best in world at something else other than being a Christian? Hope you enjoy the true story of a Stone Mason.
Blessings
Joseph De Buglio

Apparently it is true. At a recent church meeting where a 160 year old Roman Catholic Church is being restored, the acoustical treatment that I designed will also help to preserve the walls behind it. The acoustical panel will carry current and future artwork while the walls behind the acoustical system will be sealed. With no paint going onto the walls, the existing brick and concrete will no longer be degraded by the chemicals in the paint. This could be the first time where acoustics, Church Iconic Art and preservation are combined together. According to the restoration company, this approach could double or even triple the cycle between major restorations. The church has already been partially treated for sound acoustics and the improvements have convinced church leaders that the rest of the room should be treated as well. For this church, no absorption is being added. Only diffusion is being added to create a phase coherent worship space. The restoration company thinks that adding acoustical treatment system an affordable way to extend the cost of the restoration and it will give better results for hearing and the sound system performance.

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.

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
