Abstract

Illusory sensations about posture and motion can be perceived in various cases. Self-motion and body sway caused by virtually moving sound-source images were investigated. The center of pressure and the sensation level of self-motion were measured and analyzed to discuss their characteristics in terms of the interaural time difference (ITD) and interaural level difference (ILD) caused by moving sound. As a result, ITD and ILD larger than those for 30 deg had an influence on self-motion and body sway. In addition, the azimuths that corresponded to ITD and ILD did not need to be matched.
