| Research Abstract |
Human can perceive size of an object(sound source) using not only visual cues, but also auditory cues. This study aims to investigate integration characteristics for the auditory size processing and its mechanism. We performed several psychophysical experiments using vowel stimuli and investigated(a) dependence of sound duration and fundamental frequency,(b) influence of waveform periodicity, and(c) correlation with size normalization on size extraction.
