 The first thing
done in most every acoustic consult is; or should be, the running
of
analysis software, with a test signal, in
a room, and record
the “tone or image” of that room through the computers
sound card, with a calibrated mike and preamp. This determines the
room’s
abnormalities, or it’s sonic math. Additionally, use of a
decibel meter and tone/frequency generator to pinpoint problem
areas
in a room, requiring acoustic treatment.
 There
are many companies building good test equipment, and software , but
we’ve been working with something as simple as etfacoustic’s “Energy,
Time, and Frequency’s 5.X” software and it’s
designer, Doug Plumb. Finding the problem, with a test system
is relatively simple,
but designing, fabricating and installing a treatment system,
once it’s
tested, is a bit more difficult, and is subject to a real world,
mechanical principle.
 Do
your doors, windows and light switches, allow you to treat the
areas you need to? How does that treatment look and perform
once it’s installed? How accurate are your mixes?
- An analysis of room with printed
reports
- The consult and proposal of
the acoustic treatment system
- The installation of either
custom or modular acoustic treatment

Back in the “old days”, (I don’t mean the building of the pyramids), we commonly incorporated the
use a plum bob (a weight hanging from a string) and a chalk box (a string loaded with a colored chalk)
as our means to achieve accuracy, and a straight line.
The laser has revolutionized all industry, and our use of that technology has been the accuracy
of our builds, and the alignment of our systems; be it the walls, ceilings or speakers. The computer,
at an affordable price, now allows us to see information we never could, or never will be able to hear,
especially after years of abuse to our hearing playing music. |
