The detection, loudness, and discrimination performances of subjects with normal hearing were assessed using 3 five-component tonal complexes (1020-1100 Hz) with crest factors of 1.8, 2.6, and 3.2. The 3 five-component tonal complexes were: (1) equally detectable in broadband noise when presented at equal rms amplitude; (2) perceived as equally loud when presented at essentially equal rms amplitude; and (3) discriminable from one another when presented at equal loudness. The present data indicate that listeners can make discriminations on the basis of amplitude variations.
使用3个波峰因数分别为1.8、2.6和3.2的五成分音调复合体（1020 - 1100赫兹）评估听力正常受试者的检测、响度和辨别能力。这3个五成分音调复合体：（1）以均方根振幅相等呈现时，在宽带噪声中具有同等可检测性；（2）以基本相等的均方根振幅呈现时，被感知为响度相同；（3）以相等响度呈现时，彼此可辨别。目前的数据表明，听众可以根据振幅变化进行辨别。
