This study was carried out to investigate sound sensation of Korean traditional silk fabrics with similar sound pressure levels (SPL) and to identify secondary physical factors excluding SPL which determine sound sensation of the fabrics. Sounds of the silk fabrics tended to be perceived differently from one another as for some of sensation such as clearness ant roughness. They were felt more strongly in aspects of loudness, roughness, and highness than of softness, sharpness, clearness, and pleasantness. Subjective clearness, roughness, and highness were significantly correlated with some of sound parameters including roughness(z), ${\Delta}L,\;and\;{\Delta}f$. Especially, both of clearness and roughness which were varied among the fabrics were found as determined by ${\Delta}L$. This result means that ${\Delta}L$ as well as roughness(z) and ${\Delta}f$ could be utilized secondary to SPL in order to satisfy some of human sensibility for sound from traditional silk fabrics without variation of physical loudness.

Subjective touch sensation for Korean traditional silk fabrics was evaluated, in order to compare tactile sensory aspects of Korean and American subjects and to determine mechanical properties of the fabrics affecting the sensation psychophysically. Eight aspects of touch sensation including hardness, smoothness, coarseness, coolness, pliability, crispness, heaviness, and thickness were rated by semantic deferential scale. The mechanical properties of fabrics were measured by Kawabata Evaluation System (KES). Both of Koreans and Americans showed fairly similarities to each other in subjective smoothness, coarseness, and crispness. On the contrary, as for coolness and pliability, Koreans were found as feeling the silk fabrics more sensitively than Americans were in that they rated some of modified leno fabrics as very cool and stiff in touch. Coolness and pliability by Koreans were affected mainly by surface and bending properties while those by Americans were determined mostly by compressional and tensile characteristics as well as sulfate properties
