Abstract
Noise is an unpleasant sound generated from high level sound source, which is a major concern on the residential areas and disturbed comfort, safe activity performance and human health. Now a days, most people are interested on light weight, having good mechanical strength and biologically degradable as well as compostable products. The aim of this research work was characterized the acoustic properties of new alternative ecological composite materials using low cost and light weight agro waste resources. The sound absorption performance of enset fabric and its composite were determined using two microphone transfer mechanism with impedance tube method. The porosity and void structure of enset fibers were studied by scanning electron microscope (SEM) for analysis of enset fabric/enset fabric composite sound dissipation mechanism. The sound absorption coefficient of enset fabric reinforced green composite had a value of 0.9 at critical frequency of 4500 Hz. The test result revealed that, enset fabric had better sound absorption capacity than commercially used glass fabric and had a promising potential to substitute flax in ecofriendly automobile and construction sectors with a wide range of acoustic absorbing frequencies, 3000 Hz - 6000 Hz.
