| Research Abstract |
In this study, we investigated the equivalent perception among the feeling of depth of a visual stimulus, the point of subjective equality (PSE) of the sound pressure level (SPL), and the point of subjective simultaneity (PSS) of a visual stimulus and its associated sound. We obtained the followings : the PSE of SPL intended to decrease when the delay time increased (the sound was delayed), the feeling of depth of the visual stimulus moved to far away when the sound stimulus was delayed, the PSS hardly changed when the SPL was varied, the feeling of depth of the visual stimulus moved to near when the SPL increased, and the sound transfer functions (STFs) could be effective as a cue of the equivalent perception between the auditory and visual stimuli in relatively short distances.
