Nothing can improve the
quality of your church sound system as much as determining the proper placement
for your loudspeaker system.
Upgrading your speakers can
make changes in the range of 1 to 5 decibels. But simply changing your
speaker position can make differences in excess of 15dB in response! Who
would buy a loudspeaker product with a +/-15dB swing in response? Regardless
of what speaker system you currently use, a basic understanding of the
room & loudspeaker interaction and the applied fundamentals can help
you make a substantial improvement in your systems performance.
There are no magic formulas
for ensuring great sound in every room. We can however, identify and gain
an understanding of basic acoustical principles. Some basic equipment including
a 20' measuring tape, a test CD with a variety of test tones, an inexpensive
analog sound pressure level meter and a calculator can reveal more information
than you may want to know.
Like a speaker, every room
has its own frequency response. To make things more complex, the response
varies with the listener's location and the room's dimensions construction,
and furnishings. Room dimensions determine standing wave frequencies. In
general, rooms with dimensions that are divisible by a common factor, like
10' x 20' x 30' tend to compound standing waves at one frequency.
