Where are the Carboard Tubes

Posted by jdbsound on August 28, 2017

Churches use a lot of Cardboard Tubes in acoustical room fixes because they are very effective in getting the room performance they want and need.  Cardboard Tube not only outperform all other acoustical products in churches but they are also the most affordable.  There is nothing that can do what half round tubes can do, even at 40 times the cost.

Ok then, what if you don’t like the look of cardboard tubes around your worship space.  Here is an option some churches have been willing to spend a little extra for.

These look like standard 5 inch deep absorbing panels.  They are not.  These are Sono Tubes mounted in a wooden frame and covered with cloth.

The cloth was an added expense and it was worth it.  The fire rated cloth is expensive and before covering the panels, you want to make sure the acoustical system is going to work and work it did.  The church is very happy with the results and they are enjoying the room.

This is what the installation looked like before it was covered.  The wooden frame has no effect on the performance of the half round tubes.  The cloth only affects frequencies above 10,000 Hertz which means they have no effect on speech or music.  In this installation three sizes of tubes were used.

At the bottom is a huge video wall screen.  On the wall are the Sono Tubes.  Yes, the tubes will work behind a vinyl screen.  If you notice the pattern of the diffusers on the wall. that pattern was needed to control lower mids and bass sound energy.  This pattern was pretested in our test room.

Here is the finished installation of the video system.  It takes three projectors for each screen.  The centre screen is a video wall.

Calvary Worship Centre, Surrey, BC. Canada

The acoustical system at Calvary Worship Centre is now about 95% complete.  The church hired me back to confirm the acoustical results and to finalize the sound system setup.  The Midas Pro2c Mixer and Danley Speaker system are a great match.

This is not the largest church to use this acoustical and sound system combination, but it is the largest church to change their acoustics in less than 30 days.  The fastest church repair was done in 7 days in Brentwood, England.  The largest Church I have worked on was 6500 seating.

A member of Living Hope Church in Surrey BC where they have been using the same acoustical system for over a year commented with saying Calvary has the same balance of sound as does Living Hope which is a modest 270 seat church.  Calvary Worship Centre can seat up to 2000.  That is remarkable considering that one place is built as a “proper” church and the other is a converted warehouse and both spaces perform the same.  (I was reminded that Living Hope Church thought they already had good acoustics but tried the Solomon system as a short term experiment.  The experiment turned it a permanent installation and the congregational singing and worship has never been more exciting.)

A Member of Calvary Worship Centre said, “The sound is far better than I dared hope for this 20,000 sq ft space given my previous church experience in a very similar venue.  Also, the total price was less than I expected it might be including your fees and the acoustic treatment.”

As one person mentioned at another church fixed with half round diffusers in Little Rock, Arkansas USA, he said, “you can tell if you have a good room by the number of people singing.  Before only about 20% of the audience was singing most of the time and for familiar hymns about 25% were singing.  Now it’s about 85% of the audience is singing all the time and you can hear the excitement and power of all those voices ring out.”  Imagine that – worship and excitement in the same sentence.

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
