探讨了声音分离线索对强度增量敏感性的影响。听众指出，是否第二和第四声（谐波复合）内的五个声音序列的强度增加。目标声音具有250 Hz的基频。在不同的条件下，非目标声音有不同的基频，不同的频谱形状，和独特的频率区域相对于目标。对于比非靶更强烈的靶，非靶特征不影响阈值。对于目标强度低于非目标，阈值提高时，目标和非目标有独特的频率区域。
The effects of sound segregation cues on the sensitivity to intensity increments were explored. Listeners indicated whether the second and fourth sounds (harmonic complexes) within a five-sound sequence were increased in intensity. The target sound had a fundamental frequency of 250 Hz. In different conditions, nontarget sounds had different fundamental frequencies, different spectral shapes, and unique frequency regions relative to the target. For targets more intense than nontargets, nontarget characteristics did not affect thresholds. For targets less intense than the nontargets, thresholds improved when the targets and nontargets had unique frequency regions.
