4-1 Perceptual effects of visual cues on sound images moved up or down along multiway loudspeakers set up perpendicularly

Abstract

Perceptual effects of visual cues on sound images moved up were investigated with eight loudspeakers and lamps perpendicularly set up. The results show that the perceptual origin point of a sound image can be influenced by the visual stimulus with the duration of 1.5sec presented at the beginning of sounds.
