The maximum number of streams that could be heard from a mixed sound was measured. In each trial a mixed voice and a single voice (probe) were successively presented. The 7 adult subjects were required to judge whether, or not, the probe was present in the multiple voices. The perceptual limit (the maximum number of streams) was calculated by multiplying the true hit ratio with the number of speakers. The estimated perceptual limit was approximately 3 when more than 4 speakers were presented. The results indicate that auditory processing is more effective than previously believed (cf. Kashino & Hirahara, 1996). The data indicated that the probe could be detected more easily when it was presented before the mixed voices rather than after the mixed voices. This may indicate that the perceptual limit results from a limited attention capacity.
