Abstrak: Panel
of foam concrete
wall is a type
of membrane panel
which has maximum
sound absorption and can create
quite and environmentally friendly
room. The purpose of
this study was to determine
the magnitudeof the sound
absorption value using the Sabine formula in Reverberation Chamber at
Syiah Kuala University acoustic laboratory. The result of this study show that
peak value curve sound absorption of 0.67 accurs at the frequency of 250 Hz,
and painting of the panel surface can increase the value of sound absorption to
be 0.76
at the frequency
of 250 Hz,but
the slope of
sound absorption value
sharply decreased to be
0.07at the frequency
of 1000 Hz.
Treatment on the
panel surface can increase or decrease the value of sound
absorption especially at the low frequency regions.
Keywords: Panel of foam concrete wall, Sabine formula, The
value of sound absorption
