- Textiles are used in most industries, due to theirspecific physical and mechanical characteristics. Thesematerials are used as sound absorbent because of their porousstructures. Moreover, textiles are less expensive, lightweightand recyclable. This article reviews the mechanisms,experimental modeling and research that has been done inthe last two decades in the field of sound absorption in fibers,carpets, composites, woven fabrics, knitted fabrics, andspacers. There are several parameters affecting the soundabsorption 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 thesound absorption behavior at different frequencies. In thisarticle, it has been tried to provide general and partial specificinformation about sound absorption properties of textiles. Itis noteworthy to mention that some research results are inconflict with each other.
