Description
Summary:In recent years, textile goods have come to be widely used as soundproofing, because of their two important advantages, low production costs and light density, in relation to other soundproofing materials. These intrinsic parameters are very important in some industries such as the automobile and aircraft industry. Although, previously, nonwovens had a wide application as soundproofing among textiles, it seems that weft knitted fabrics can also be a suitable substitute due to their pleasant appearance in comparison to nonwoven fabrics. In this paper, by incorporating two theoretical models presented for nonwoven and plain knitted fabrics, a suitable theoretical model is obtained for calculating the sound absorption coefficient of weft knitted fabrics with complex structures and, finally, the results of a theoretical model are compared with experimental results.
