Sound Absorption Performance of Micro-Perforated Panel (MPP) Made from Biodegradable Composite (Hibiscus Cannabinus+PLA) Material

Article Preview

Abstract:

Micro-perforated panel (MPP) has been widely considered as a very promising alternative in absorbing sound by utilizing the concept and mechanism of Helmholtz resonator. Most of the existing MPP are made of metallic material such as aluminium or stainless steel. In this study, biodegradable composite micro-perforated panel (BC-MPP) made from kenaf fibre and polylactic acid (PLA) will be implemented. Impedance tube test shows that BC-MPP possessed excellent sound absorption properties and could rival with conventional MPP. The peak absorption of BC-MPP is also more significant compare to conventional MPP as the peak absorption almost reaches unity.
