Experimental investigation on sound absorption property of a panel board using maize stem

Abstract

In this project our aim is to produce a soundproofing board which is made out of Maize stem (stalk). Due to increase in number of industries, factories and vehicle traffic cause serious noise pollution. So to overcome this, use of Sound proofing panels in the structural elements could significantly help to reduce the sound as well as gives a good environment to work. People nowadays demand for a better working environment. Many commercialized sound proofing materials are available in the market, the cost of these materials would be much higher and also it could cause health issues when people are exposed with the material. So use of sound proofing panels made with agro-waste could be a better solution, an attempt has been made to produce a soundproofing board which is made out of stalk portion of maize plant. The board's sound absorption property is studied in this research by using Impedance test and the cost of maize stem board is cheap enough so that everyone can afford it.
