Abstract: The probability of
application of palm fibre from arenga pinnata appear as best treatment for
sound absorption material which can be used in controlling noise. The objective
of this study is to determine sound absorption coefficient value of palm fibre
through a testing the absorbent material, by applying sabine reverberation time
formulation in reverberation chamber at Thermal and acoustics laboratory Syiah
Kuala University. Result of this study show that sound absorption coefficient
value is obtained 0.97, at 2000 Hz. Whereas thickness of material 20 cm with
density of 150 kg/m3. Addition of density can increase sound absorption
coefficient value in frequency range 1/3 octave. Proven that a comparison palm
fibre and artificial material and consequently palm give better quality values
because it economic value and friendly environment.
Keywords: palm fiber,
