Abstract

This study was performed to measure fabric sound objectively and to relate the sound with human subjective sensation. Rubbing sound of each fabric was generated by an apparatus devised for this study and transformed into sound spectrum by fast fourier transform (FFT) analysis. As sound characteristics, level pressure of total sound (LPT), amplitude difference (ΔL), and frequency difference (Δf) were obtained. Seven sensation (softness, loudness, pleasantness, sharpness, clearness, roughness, and highness) and satisfaction for sound of each fabric were rated by free modulus magnitude estimation (FMME). The LPT of polyester taffeta was the highest (62.1dB) while the value of polyester ultrasuede was the lowest (37.4dB) among the fabrics. Values for level range (ΔL) of eight fabrics were ranged from 18.6dB to 52.4dB. Frequency difference (Δf) of all fabrics had negative values. Eight fabrics showed significant differences one another in each of sound sensation. Among the sensation, loudness, sharpness, roughness and highness were negatively correlated with sensation of softness and pleasantness. A regression model of each sensation was fitted as a function of sound parameters. Loudness, roughness, and highness were well predicted by sound parameters showing R 2 higher than 0.7.
