Abstract
ABSTRACT Sound absorbers play a significant role in keeping a quiet and noise-free environment. Both synthetic and natural materials can use to control noise. Currently, natural materials are a valid alternative to conventional synthetic materials. This paper aims to study the physical parameters of Grewia Optiva fibers. The theoretical models’ assessment has been carried out to calculate the sound absorption coefficient with the help of Scilab software for synthetic (melamine foam, polyurethane foam, and mineral wool) and natural (kenaf fiber, coir fiber, and Grewia Optiva fiber) materials. The results from the simulation conclude that the sound absorption coefficient of Grewia Optiva fiber is almost similar to or much better than other synthetic and natural sound absorbers. Hence, Grewia Optiva fibers can be a valid substitute for traditional sound absorbers for sound absorption purposes.
