| Summary: | This paper highlights the sound absorption performance of microperforated
panel (MPP) made from coconut fiber and polylactic acid (PLA) composite
named as biocomposite microperforated panel (BMPP). Coconut fiber was
used to produce BMPP specimen and PLA was used as matrix. Impedance
tube method was employed to identify the sound absorption performance of
BMPP specimen while a porosity tester was used to determine the porosity of
BMPP specimen. Comparison on the sound absorption performance
between BMPP and steel MPP will be discussed in this paper. It has been
found that BMPP with different composition percentage of coconut fiber and
PLA possessed different sound absorption performance mainly due to the
existence of pores and tortuous structure within the specimen itself.
Scanning electron microscope (SEM) scan was performed to further analyze
the structure of BMPP specimen. |
