Study on Nature Fiber Composite for Noise Material Control

Abstract

Transportation tracks of railways and highways are the highest noise pollution contribution to the inhabitant urban due to the sources near residential areas. Many researchers proved that the composite material could help reduce the noise by 30%. This study focuses on designing local nature fiber composite for developing a good sound absorption material by providing experimental methods. Three natural fibers of coconut, palm oil, and sugarcane are used to make a composite by varying filler content for sound absorption and transmission loss observation. The results found that sugar cane bagasse is suitable for average performance in varied filler content for both sound absorption and transmission loss. The overall results showed a successful improvement in both sound absorption coefficient and transmission loss with the addition of fiber content
