Periodic body sway caused by sound source movement through hearing sensation

Illusory sensations of posture and motion can be perceived in some situations. For example, visually induced self-motion has been studied, while we can demonstrate self-motion and body sway caused by virtually moving sound-sources. We investigated such self-motion and body sway. The center of pressu...

Description
Summary:Illusory sensations of posture and motion can be perceived in some situations. For example, visually induced self-motion has been studied, while we can demonstrate self-motion and body sway caused by virtually moving sound-sources. We investigated such self-motion and body sway. 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, periodic body sway synchronized with sound source movement was observed. Larger ITD and ILD had an influence on self-motion and body sway. In addition, azimuths for ITD and ILD did not need to be matched. Characteristics of auditory induced body sway might be expected to apply for healthcare and fitness fields.
