Since entering the
acoustics arena in the seventies, we
have heard many stories over and over.
One of these is that egg cartons can be
a substitute for
acoustical foams or other
sound
absorbers as an acoustical treatment
for use in broadcast & recording studios
or other critical listening
environments.
After
listening to this many times, I decided
to include formed paper egg cartons
with a test of some
commercial products at Riverbank
Acoustical Laboratories.
Egg
Cartons do, indeed, have acoustical
value.
They measure NRC = 0.40.
However, the graph tells the rest of the
story. While commercial products exhibit
a smooth curve, there is a "pothole" in
the acoustical road with egg cartons.
Another thing to consider is
flammability. Take an egg carton outside
and put a match to it! Then
ask yourself, "Do I still want this on
my studio walls?" |
