This study is performed to determine the characteristics of fabric sounds and the
mechanical properties to predict their auditory comfort. In order to obtain quantitative
information about emotional changes evoked by fabric sounds, physiological signals are
acquired and analyzed when each fabric sound is presented to participants. Physiological
parameters employed in this study are electroencephalogram and autonomic nervous
system activities, including photoplethysmogram (PPG), skin conductance level (SCL), and
the ratio of low frequency to high frequency (LF/HF) from the power spectrum of heart rate
variability. As sound parameters, the pressure level of total sound (LPT), loudness(z), and
sharpness(z) are calculated. Mechanical properties of the fabrics are measured with the
KES-FB system. Bending hysteresis and weight. reflect negative sensations, influencing
slow alpha, LF/HF, and SCL. Among sound parameters, LPT, loudness(z), and sharpness
(z) influence negative sensations, causing the increment of SCL and LF/HF with the
decrement of slow alpha and PPG.
