Abstract:

For sustainable development of the textile industry must find solutions to reduce waste and decrease noise at work. Of textile waste are obtained boards of different thicknesses, which aim to be wide field of use. For it is to achieve some experimental results about the soundproofing of plate types: is studying recoverable boards made of short textile fiber and cork boards. Textiles have a thickness of 3 mm and 10 mm and cork boards with a thickness of 3 mm and 10 mm. For determining is used the impedance tube reading BrĂŒel&Kjaer, type 4206. By analyzing the absorption coefficient results that materials have absorbing characteristics that increase with material thickness. From these boards aims to obtain laminated composite materials used to encapsulate industrial noise sources.
