Quote of the Day

Posted by jdbsound on January 10, 2013

If experiencing poor sound in church could be measured as pain and people are not complaining about it, it could be because they don’t consider taking 10 extra strength pain killers per worship service as overdosing.

All Sound Systems are like magnifying glasses of the room acoustics

Posted by jdbsound on December 10, 2012

Is your sound system making the right impression?  Are the acoustics of your church allowing your sound system to make that great first, second and third impression at your church?

Once again the subject of getting more performance out of the next sound system upgrade keeps coming up. When a church is constantly seeking to get more performance out of a sound system at every upgrade and not be  enjoying the best sound possible then it’s time to fix the room instead of putting it off and investing into more equipment. This is the message your sound system is broadcasting.  Are you listening or are you waiting for the next technology breakthrough for that sliver of improvement?

Is Social Media and Sermons on YouTube or Web Streaming replacing the need for good sounding worship spaces?

Acoustician vs Architects

Posted by jdbsound on June 11, 2012

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

Posted by jdbsound on May 25, 2012

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

  1. Seating capacity 500+
  2. Ceiling over 40 ft high
  3. Over 120 Cardboard Tubes custom made order and placed around the room in 8″ 12″ and 16″ half rounds.
  4. Between 120 to 800 hertz removed 18 to 22dB of excess energy.
  5. This change allowed a single speaker system to cover a whole room 134 ft long.
  6. Throw distances from speakers to back wall, 98 ft.
  7. Contractor who installed the system was surprised at how well this sound system worked and how much the room changed.
  8. Contractor suggested delayed speakers before the acoustical treatment was done.

Excess Noise At the Pulpit or Altar or preaching area

Posted by jdbsound on May 22, 2012

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?

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

The skill of the average human ear

Posted by jdbsound on May 22, 2012

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.
