| Research Abstract |
Sensation of sounds is mediated by temporal, local fluctuation of air pressure which is mostly propagated from sound sources, i. e., physical objects. The constancy of the source size is assumed to be a reliable cue for sound source segregation. The purpose of the current study was to investigate effects of the temporal change in a resonant scale corresponding the source size on auditory streaming. Results of several psychophysical experiments indicated that the resonant scale information could be extracted in a fast process, and that its rapid alternation could cause stream segregation in a systematic manner.
