Abstract

Utilization of biomass for green products is still progressing in the effort to provide alternative clean technology. This paper presents the utilization of natural waste fibers from paddy as acoustic material. Samples of sound absorbing material from paddy waste fibers were fabricated. The effect of the fiber density, that is, the fiber weight and the sample thickness, and also the air gap on the sound absorption coefficient is investigated through experiment. The paddy fibers are found to have good acoustic performance with normal incidence absorption coefficient greater than 0.5 from 1 kHz and can reach the average value of 0.8 above 2.5 kHz. This 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 coefficient.

稻谷废纤维生物质作为可持续声学材料

在提供替代清洁技术的努力中，利用生物质生产绿色产品仍在取得进展。介绍了稻谷天然废纤维作为声学材料的应用。以稻谷废纤维为原料制备吸声材料。通过实验研究了纤维密度(即纤维重量、试样厚度)和气隙对吸声系数的影响。稻谷纤维具有良好的声学性能，1 kHz以上的法向入射吸收系数大于0.5,2.5 kHz以上的平均吸收系数可达0.8。该结果可与商用合成玻璃棉相媲美。单层聚酯织物的附着可以进一步增加吸收系数。
