Effective Parameters, Modeling, and Materials in Sound Absorption: A Review

Textiles are used in most industries, due to their specific physical and mechanical characteristics. These materials are used as sound absorbent because of their porous structures. Moreover, textiles are less expensive, lightweight and recyclable. This article reviews the mechanisms, experimental modeling and research that has been done in the last two decades in the field of sound absorption in fibers, carpets, composites, woven fabrics, knitted fabrics, and spacers. There are several parameters affecting the sound absorption of textiles, and the effectiveness of each parameteris specific to each textile. Therefore, the best usage of eachkind of textiles can be determined through considering the sound absorption behavior at different frequencies. In this article, it has been tried to provide general and partial specific information about sound absorption properties of textiles. It is noteworthy to mention that some research results are in conflict with each other.
