Not all churches have
an acoustical engineer in the neighborhood. But most every church
has a good sound tech who can be guided into administering a number
of sound tests and recording the results. ASC works with the technical
staff and the equipment that already exists in the church to test
the sound system of the church. The church sound tech learns to
record the results of the testing and send the recording to ASC
where they are analyzed. A report is generated which contains printouts
of all the test data and an analysis of that data.
RT-60 Analysis
ASC
uses the "balloon burst" test to determine the RT-60 (reverb)
in your Sanctuary. The RT-60 test will indicate the amount of time
it takes for sound to decay 60dB (decibels). This information can
be very useful in making determinations of proper acoustical treatment
for the specific size and use of the room. ASC sound-absorbing materials
can be used to control reverberation so speech will not be garbled.
The larger the room volume, the longer the reverberation time because
sound waves will encounter room surfaces less often than in small
rooms. Proper sound absorption can make the sound seem to come directly
from the actual source rather than from everywhere in the room.
ASC provides an RT-60 analysis
which comes with a full data summary and charts for $300.
