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.

How to Know if your Church has Good Acoustics – Part 1

Posted by jdbsound on February 3, 2016

Here is the first test you can do to know if you have good acoustics.  Have two people over 40 years of age standing 40 feet apart in the sanctuary.  Have one person on stage and the other anywhere in the audience.  With the room empty, the sound system off, with the lights on and whatever mechanical system that are on during worship, have the two people start a conversation.  The person in the audience area has to be understood by the person on stage equally as well as the person on stage to be understood by the person in the seating area.  This is important as all churches are used to hear and communicate from both ends of the worship space.

If the two people can converse for 5 minutes understanding each other, chances are your church is in good shape.  If hearing and understanding at 40 feet is not good, then move in closer until you do.  When speech becomes clear, that is the free field distance of the room.

If you can converse at 40 feet well, try moving further apart.  Keep moving apart until it become hard to understand or your up against the walls of the church.  If your able to increase the distance for understanding speech, then as you get further apart, the better the room most likely is.  This is step one.

Church Ceilings

Posted by jdbsound on January 8, 2016

Tip of the day.

If your planning a new church or plan on buying or leasing a commercial building, there is no instance where a floor and ceiling that are parallel that sounds good.  Sure, there are a lot of churches and worship spaces that have parallel floors and ceiling but when compared to cathedral, vaulted or angled ceilings, there is a huge difference.

When the ceiling and floor are parallel, it is harder to manage the stage sound, congregational singing suffers and room coverage suffers too.  It is harder to get good bass sounds as the frequency is limited by the height of the room.  So if you have a 20 ft ceiling, sounds below 50 Hertz will distort as you increase the volume to “feel the sound.”

To change the room, changing the ceiling is cheaper and better than changing the floor as the angle of the floor is limited to how long people have to stand on a sloped floor.  The more time you spend worshiping on your feet, the less a sloped floor makes sense.

When you change the ceiling, you can also make the acoustical treatment tunable at no extra cost.  Tuning means you are equalizing the room passively.  This form of control remains more stable when humidity and temperature changes.  Congregational singing increases humidity within the first five minutes and temperature within the first eight minutes of worship.  If you find your mixes are falling apart after the second or third song of singing, it is because the room changed, not because of your mixing skills.

Introduction Updated – About

Nothing is more frustrating than visiting a church and not understanding or struggling to hear what is being said.  With all the science and knowledge there is, there is no excuse for any church, new or old to not have good sound.  Sadly, only five percent of the total church community has sound quality that is suited for worship.  Sure, there are some churches that have one aspect of church sound that passes but very few churches can do speech, music and congregational singing well.

Church Acoustics is one of the most difficult professions to work in. While it is complicated and the variable are infinite, it is made much easier with consistently good results when following the biblical method of controlling any room.  There are only a few people in the world that follow this method but once you experience the quality of the acoustics of one of these churches that are managed in this way, everything else sounds disappointing.

The Church Sound System is one of the easiest systems to design, install and use when you have good acoustics.  When you have poor acoustics, the sound system always fights back and lets you know where the problems are.  Until the room is tamed, no amount of sound equipment or expert knowledge can overcome the physical barriers of the room.  In an age when headsets, ear buds, HDTV, computers and home entertainment systems are of such high quality, first time visitor and members of most churches want the same quality sound at church.  When the acoustics of a church follows the Bible’s example of quality sound (which is a method detailed over 3000 years ago), it allows the modern sound system to perform as good as any contemporary form of media there is and satisfy the most discriminate of listeners while delivering the best level of speech possible.
