Abstract

The goal of this study was to implement Malaysian natural fibers as sound absorbers in acoustic panel. Four natural fibers, namely; coir, corn, sugar cane and grass were chosen and their acoustic absorption properties examined. Samples were tested in impedance tube complying with the standard ISO 10534-2. Increase in the thickness improved the absorption coefficient and samples of coir, corn and grass with 2 cm thickness absorbed more than 70% of normal incident sound at approximately f>1500 Hz. Comparison with synthetic materials having the same thickness showed that these fibers have better absorption coefficient throughout the frequency spectrum. Fiber-glass was an exception and still considered one of the best materials for acoustic insulation however it has adverse effects on human health and its utilization is no longer recommended. The results supported the viability of natural fibers as alternative to conventional synthetic absorbers in acoustic panels.
