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.

Tube Radiators not just for Sanctuaries

Posted by jdbsound on September 9, 2016

Tube Radiators work great in any room where discerning listening is required.  Whether listening for pleasure or when recording music and laying down tracks, Tube Radiators creates an ideal space for all of those activities.  india-recording-studio

Here is one such studio.  This room is both a post editing suite and recording room.  The pattern of the diffusers uses 8 and 12 inch half rounds.   Instead of using cardboard tubes, these are made of plywood.  With the room dimensions, this pattern turned out best for creating a high end, high quality performance space that allows for quicker production times.  Way to go Caleb Daniel!  You did an excellent job.

New Church Sound System Equalization Schedule

Posted by jdbsound on February 17, 2016

Notice to all Clients of JdB Sound Acoustics.

If you are in a new church building or you have done major renovations in your church, you will have to re-equalize the sound system many times in the first few years.  Here is the Schedule you should follow.

  1. First year – After the 1st month, 3rd month, 6th month, 9th month and 12th month
  2. Second year – After the 4th month, 8th month and 12th month.
  3. Third year – same as year 2
  4. Fourth year – after the 6th and 12 month.
  5. Fifth year – same as year 4
  6. Sixth to tenth year, every 8 month.
  7. After that, once a year.

It take up to ten years for most building to fully cure or longer depending on how much concrete and wood is used.  For that reason, the humidity of the church becomes lower and lower as the church ages which also changes the sound of the worship space.

Also, depending on the climate area you are in, you should be re-equalizing your church sound system for each season.  more so the further you are from the equator.  If you have a digital processor or mixer, you can have presets for the room changes.

Stone Mason Gets Passed Over

Posted by jdbsound on April 23, 2015

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

Singing at 105dBa!

Posted by jdbsound on April 10, 2015

Congregations can sing at 105dBa.  At least that is what they do in churches that I have fixed and that does happen in other churches too, that perform well.  When they do sing that loud, what do you do?  Or, what do you do when the congregation is starting to drown out the sound system?

  1. Keep pushing the sound system to keep up with them.
  2. Keep the sound system at 90dB and let the congregations voices dominate.
  3. Lower the sound system FOH levels so that the congregation can enjoy what they are doing.
  4. Push the sound system to drown out the congregation as always regardless if the sound system is distorting or not.

Please tell us what you do when mixing.

Have you already fixed your acoustics 9 times before and your still not happy?

We can fix any church that is absent of any acoustical planning and treatment.

We can also diagnose and fix any church that has the wrong acoustical treatment to get it back on track.

We have never been to a church that we couldn’t fix but we have had churches that were not ready to make the needed changes to get what they desperately wanted.  Oh, did you know that acoustics has always been the deciding factor in the aesthetics in a house of worship whether the acoustics are good or bad.  God taught us that beginning with Solomon’s Temple. (1 kings 6:29 (NIV)On the walls all around the temple, in both the inner and outer rooms, he carved cherubim, palm trees and open flowers.  (Please read my article about Solomon’s Temple http://www.jdbsound.com/art/art570.html))

Churches are not temples but they are dedicated as worship centers and houses of learning.  For worship and learning, you need tools. One of those tools is acoustics. You need a system of managing the air between the teacher and listener for the best worship and learning experience.  While a sound system is also a tool it cannot manage the air. It relies on acoustics for it to work. The better the acoustics, the more effective a sound system is.  Without the right acoustics, what are you really hearing or understanding?
