Church Sound: It Takes Three (Due To Silly Decisions)
Defining a good church sound system often requires living through several bad ones...

I could write a book on the subject of sound for churches. Unfortunately, it would have to start with stories about bad sound, and two good friends of mine published this very thing a few years ago.

The book is titled “If Bad Sound Were Fatal, Audio Would Be The Leading Cause Of Death,” by Don and Carolyn Davis, founders of one of the world’s leading audio education organizations, SynAudCon. The book is entertaining and offers a host of true stories, including many of which are historical in nature, taken directly from the lives of these two extraordinary people.

The sad truth is that while bad sound in churches is not literally killing people (thank goodness!), it does put them to sleep. In psychological education, there is the study of what has come to be known as psychoacoustics. It delves into the way the ear works in conjunction with the brain – not only how sounds that enter the ear canal get to the brain, but also, how the brain then processes these (now) electrical signals into meaningful “data” that a person can understand. 

An even more detailed study of the science of psychoacoustics reveals how the brain works its way around hearing deficiencies, background noise and other audible annoyances. While the brain is very forgiving of bad sound, enough of it in high doses eventually forces the brain to ignore the input or even shut down.

How many times have you heard a pastor or other person speaking say, “I see someone snoozing?” Of course, for the person in the pulpit, this is a truly annoying thing, and it conjures up all sorts of subconscious thoughts: “Am I that boring? Is my message over their heads? What’s wrong with them? I’ve prepared well and am delivering well, but there they go, nodding off again.” 

But the cause of sleeping in church (or other public gatherings) doesn’t have much if anything to do with the person speaking. Nor does it mean that many in the audience were out way too late the night before, or that they didn’t drink enough coffee that morning.

Nope—many times the sleeping can be directly attributed to the quality of the sound system being used to amplify the voices. A lousy system triggers an outward portrayal of the confusion that is being caused in the brain by material that is being poorly delivered to the ears of the listeners. When a high enough level of psychoacoustic confusion has been met, the mind simply moves elsewhere, likely to daydreaming or sleep.

Just One Year In
Not so long ago, I attended a Sunday worship service held in a classic church sanctuary, in order to evaluate the room’s sound system at the request of a church member. Within just one year of opening, there were far too many complaints about audio quality to ignore.

Turns out that the building’s architect had recommended a local “not-so-good” (and now out of business) sound contracting firm to work with the facility’s electrical contractor and the church committee to implement the sanctuary sound system. It is what we shall now term “Sound System Number 1.”

Some of you might know where this is going…

This system was compromised from the outset due to the location of a large, beautiful cross, lovingly built by a parishioner. The cross location was deemed unchangeable, and thus, the only saving grace would have been for a quality sound contracting firm to stand firm and argue for a different sound system design to work around the obstacle.

Unfortunately, this didn’t happen, because the contractor was only interested in turning a quick and highly profitable job.

After sitting through a service, I must say it was truly one of the worst sounding systems I’ve ever heard. As Don and Carolyn might say, it should have killed me on the spot. I left with virtually no memory of what the pastor had said.

In preparing my written evaluation, I waited until mid-week and finally composed a detailed analysis of the system, and sent this along with a two-page cover letter, the gist of which said, “the only correction to your system that will work is to tear it out, throw it away, and start over, using a competent sound contractor.” And I recommended three.

Did they follow my recommendation, which, by the way, they paid me to provide? The answer, sadly, was no.

Instead, they went back to the original contractor and told him of my concerns. He confidently replied that he could fix the system, and at a price of “just” $35,000. Of course they took him up on his “generous” offer—the classic good money after bad scenario.

Cobbled Together
Several years later, I ended up becoming a member of this particular church. By then, they had moved on to “Sound System Number 2” – a truly cobbled together thing, done with the help of a different contractor and the “input” of several church members.

Just to complicate matters a bit further, an audio equipment manufacturer was also directly in the mix.

You guessed it—another bad system design. In most of the seats, one can either hear the loudspeakers before they hear the person speaking, or vice versa. Add in some regular doses of feedback, distortion and other quirks, and it’s a fine mess. One that cost more than $80,000, by the way.

You probably know the rest of the story…

Currently, the church is in the evaluation process for “Sound System Number 3.” While that process continues, the only thing I can tell you for sure is that my wife and I are always certain to arrive very early, in order to sit in the few seats where sound is delivered without the “bonus” of psychoacoustic fatigue.

When we look around during services, we see at least a dozen folks sitting in the “worst seats,” and invariably, they’re dozing off.

Pastors, friends, sound system operators—can you now better understand why so many people are taking a nap during worship services? It rarely has anything to do with what’s being said, but everything to do with how it’s being heard.

Or not.
