Church Sound and the Gospel

Posted by jdbsound on January 28, 2019

The goal of any worship space and the church sound system is not about loudness, gain before feedback, intelligibility, special sound effects for the organ or choir, having the most talented performers in the worship team, how many wireless mics, number of channels the mixer has or the name brand of equipment you have. The goal of a church worship space and the sound system is to be a safe place where the Gospel can be presented clearly and with little to no blemishes. Where every person within the worship space can hear and understand the Gospel as clearly as when having a conversation with someone only 4 feet away and sharing the Gospel. Anything less than that goal means that the spoken word can be corrupted in the journey between the minister’s mouth and ears of all those who are listening. The Gospel needs to be broadcasted and understood as clearly as reading God’s written words.

If your church has hot spots, dead spots, good sound in these seats and poor sound in those seats, then the Gospel is not being presented equally to everyone. If your sound system has technical problems during worship often, then it is a distraction, and it can make the difference of understanding something important.

The chart below shows tangible results when your worship and sound system are tested. There should be three tests.

The first is with a test speaker. It is a point source speaker that is small enough to mimic a person’s voice.

The next test is feeding a signal directly into the sound system and test those results. This test is just about the playback quality of your sound system.

The third test is to use the test speaker 30 inches from an open microphone such as a pulpit or any microphone on a stand and test the combined results of the worship space’s acoustics direct interaction of the sound system and open mics. You can also do a second version of this test and place the test speaker 4 inches from a microphone where the microphone is 45 degrees off axis.

If all three tests are not in the Yellow section, the results will let you know if it is your sound system, the acoustics or all of the above.  This is also a better indication predicting if upgrading your sound system will improve the results you are looking for. This is also a strong indicator that your worship space needs some kind of an acoustical management system

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.
