摘要：
Listeners discriminated changes in the spatial configuration of two-to-eight consonant-vowel (CV) stimuli spoken by different talkers, all simultaneously presented from different loudspeakers in various azimuthal spatial configurations. The number of CVs, spatial configuration of the sound sources, and similarity of the talkers speaking the CVs were varied. Experiment I used a same-different procedure to determine the discriminability of different spatial configurations of multiple sound sources. In experiment II, listeners determined the direction (clockwise or counterclockwise) of sound source rotation over eight rotational steps. In both experiments, performance declined as the number of sound sources increased beyond two. (C) 2019 Acoustical Society of America
