Normal hearing listeners discriminated a change in the number of talkers speaking consonant-vowel pairs between two auditory scenes. The number of talkers (n = 2, 4, 6, or 8) in one scene was incremented by Δn talkers (Δn = 1-8 talkers, depending on n) in the other scene. The perceptual size of the auditory scene seems to be small, as discrimination performance reached an approximate 0.75 proportion correct asymptote for n > 4. The independent variable of overall level differences affected performance, but both spatial configuration and talker similarity had very little effect.
