Utilization of biomass for green products is still progressing in the efort to provide alternative clean technology.his paper presents the utilization of natural waste ibers frompaddy as acousticmaterial. Samples of sound absorbingmaterial frompaddy waste ibers were fabricated.he efect of the iber density, that is, the iber weight and the sample thickness, and also the air gap on the sound absorption coeicient is investigated through experiment. he paddy ibers are found to have good acoustic performance with normal incidence absorption coeicient greater than 0.5 from 1 kHz and can reach the average value of 0.8 above 2.5 kHz. his result is comparable against that of the commercial synthetic glass wool. Attachment of a single layer of polyester fabric is shown to further increase the absorption coeicient.
