In this paper we examine whether visual motion induces a sensation of motion for a static sound in order to investigate dynamic visual-auditory interactions in the virtual environment. The dynamic interaural time difference ( ITD) was employed as the cue for sound motion, and the effect of the size of the visual stimuli on biasing the perceived direction of dynamic ITD was examined. As a result, induced motion sensation for static sound was obtained, and its direction was dependent on the size and direction of the applied visual stimuli. For a small visual stimuli ( an I -deg disk), sound with a static ITD moved in the same direction as the moving visual stimuli. For a large visual stimuli (a 90-deg random-dot pattern), however; sound with a static ITD moved to the opposite direction to that of the moving visual stimuli.
