Abstract : Sound absorption was one of the major requirements to improve the living environment. One of the methods to do that is provided by sound absorber. Commonly, multi-layer sound absorbers are applied to absorb broadband noise that was composed of perforated plates, air space and porous material. However, multi-layer sound absorbers? effectiveness depends on their construction. This study was conducted to investigate the acoustic properties from 100 Hz to 4000 Hz using rice husk as a sound absorptive material. The effects of porous layer backing and perforated plate on the sound absorption coefficient of sound absorptive material using rice husk were studied in this paper.
