Abstract:
To control noise pollution, the sound intensity should be reduced to a level comfortable for humans. The use of textile products especially with porous structures for noise absorption applications is one of the most widely used methods of noise reduction. Therefore, in this study the acoustical properties of porous woven fabrics based on noise reduction coefficient (NRC) and noise absorption coefficient (NAC) were evaluated. Effects of weft density and type of porous yarns, namely hollow and micro-porous yarns and also hollow yarns hole size at different frequencies were studied. Analysis of variance and Duncan test at 95% confidence level were performed to evaluate the difference between the acoustical properties of samples statistically. The results determined that weft density and yarn type had a significant effect on acoustical properties of woven fabrics. In addition, fabrics woven by micro-porous yarns showed a better noise reduction procedure.
