| description | Arenga pinnata is an abundantly natural fiber that can
be used for sound proof material. However, the scientific data of
acoustics properties of Arenga pinnata was not available yet. In this
study the sound absorption of pure arenga pinnata was measured. The
thickness of Arenga pinnata was varied in 10 mm, 20 mm, 30mm,
and 40mm. This work was carried out to investigate the potential of
using Arenga pinnata fiber as raw material for sound absorbing
material. Impedance Tube Method was used to measure sound
absorption coefficient (α). The Measurements was done in
accordance with ASTM E1050-98, that is the standard test method
for impedance and absorption of acoustical materials using a tube,
two microphones and a digital frequency analysis system . The
results showed that sound absorption coefficients of Arenga pinnata
were good from 2000 Hz to 5000 Hz within the range of 0.75 – 0.90.
The optimum sound absorption coefficient was obtained from the
thickness of 40 mm. These results indicated that Arenga pinnata fiber
is promising to be used as raw material of sound absorbing material
with low cost, light, and biodegradable. |
