Abstract

水平面放射線上において小型球形スピーカを移動させた接近・遠離音を実耳受聴した場合、それをバイノーラル収録し再生した場合、距離を変化させたHRTFで合成したバイノーラル音を呈示した場合の、音像の動きの聴こえ方を明らかにする聴取実験を行った。その結果、正面方向において頭内定位する場合を除き、すべての方向で音像が接近・遠離移動した。45°、315°において音像がこめかみあたりに近づいてから耳元に移動した。

In order to clarify the perception of a moving sound source that approaches to a head or retreats from a head, we have conducted listening tests under three conditions. Listeners listen to (1) moving sounds emitted form a moving loud speaker with actual ears, (2) binaurally recorded the moving sounds via headphones, and (3) synthesized binaural moving sounds using listener's own head-related transfer functions measured with reciprocal method via headphones. In all conditions, all listeners perceived out-of the head moving sound image that approached to a head or retreated from a head except for the frontal direction. Distance sense of the moving sound presented at front was small and apt to be localized inside the head when presented via headphones. In diagonally forward right and left directions, i.e. 45° and 315°, the sound image moved backward to the ear in the temple area when the sound source moved very close to the head.
