Sound insulation constitutes one of the major requirements for human comfort today. Sound insulation requirements in automobiles, manufacturing environments, and equipments, generating higher sound pressure, strives the need to develop more efficient and economical ways of producing absorption materials. Traditionally, economics of the research has enforced the researche to focus on industrial nonwoven textile waste. Recently hygene and environmental protection has become another major requirement, resulting in more environmentally benign, natural materials to be used in such applications. Within this book, an industiral waste, developed during the processing of tea leaves was investigated for its sound absorption properties as opposed to a standard woven textile cloth and polyetilen and polyester based nonwoven fibers composed from textile waste. The results show us many Industrial Waste can cycle sound absroptiin material. This book lead to economics benefits and natural products.
