Abstract
Material used for noise control applications should possess good sound absorption and dampening properties. In this work, the authors have focused on noise control applications of novel material made of jute which is a readily available, cheap and biodegradable natural fiber. Based on physical, flammable and acoustical properties, jute felt shows good sound absorption properties which has been used for noise control in a domestic clothes dryer and a vacuum cleaner. The noise sources in these appliances were ranked by measuring their radiated sound intensity levels. An overall reduction of radiated noise levels of 6 dB and 10 dB were obtained in the domestic dryer and the vacuum cleaner, respectively, by using the developed jute felt.
