Abstract

To investigate the sound generated by fabric friction, which simulates real wear conditions, a 'fabric friction sound generator', which simulates body movement was developed. Fabric sounds from three specimens were generated by the fabric sound simulator and recorded using high performance microphones. Physical sound parameters such as sound pressure level (SPL), level range (${\Delta}L$), and frequency difference (${\Delta}f$) were calculated for the fabrics. All the physical parameters (SPL, ${\Delta}L$, and ${\Delta}f$) of fabric sounds generated by the fourth-generation apparatus had lower values compared to the values obtained with the third-generation apparatus. Unlike the third-generation system, which generates fabric sounds by reciprocating friction, the fourth-generation system was designed with silicon-based arm-and-leg shaped abraders so that the levels of noise and fabric sounds generated were lower at all speeds.
