Abstract
In order to investigate the relationship between the characteristics of fabric rustling sounds and the mechanical properties of fabrics, the rustling sounds of 18 selected fabrics were produced and recorded by the sound generator developed for this study. The sounds recorded were analysed in the forms of sound spectra presented in terms of sound pressure and frequency through FFT analysis. Sound spectrum of each specimen was fitted by Autoregression (AR). Coefficients of the functions were considered as characteristic parameters of the sound of specimens. Mechanical properties of specimens were measured by KES-FB. Relationship between characteristic parameters of fabric sounds and mechanical properties was investigated by correlation coefficients and linear regression. Tensile linearity (LT), shear stiffnesss (G), and shear hysteresis (2HG, 2HG5) showed significant positive correlations with $\alpha$, an AR parameter related mainly to sound loudness of fabric rustles. Through linear regression, the shear hysteresis (2HG) proved to be the most powerful property with relation to characteristics of fabric rustling sounds parameter ($\alpha$).
