Study on the Acoustical Properties of Natural Jute Material by Theoretical and Experimental Methods for Building Acoustics Applications

Noise control treatment is essential to maintain a quiet and comfortable environment in buildings. In order to control noise, sound absorbing materials play a significant role. Nowadays, natural materials have gained importance in noise control field. In this study, acoustical characterization of a natural material jute is performed using experimental and numerical techniques. Normal incidence sound absorption coefficient and sound transmission loss of building materials using jute are predicted using the transfer matrix method. The theoretical and numerical predictions show a good match with the experimental data in the mid and high-frequency range of interest.
