Sound insulation constitutes one of the majorrequirements for human comfort today. Soundinsulation requirements in automobiles, manufacturingenvironments, and equipments, generating higher soundpressure, strives the need to develop more efficientand economical ways of producing absorptionmaterials. Traditionally, economics of the researchhas enforced the researche to focus on industrialnonwoven textile waste. Recently hygene andenvironmental protection has become another majorrequirement, resulting in more environmentallybenign, natural materials to be used in suchapplications. Within this book, an industiral waste,developed during the processing of tea leaves wasinvestigated for its sound absorption properties asopposed to a standard woven textile cloth andpolyetilen and polyester based nonwoven fiberscomposed from textile waste. The results show us many Industrial Waste can cyclesound absropti n material.This book lead to economics benefits and naturalproducts.
