测量了两组听者对耳间时差（ITDs）的敏感性，一组听者听力正常，一组听者感觉神经性听力损失。在安静和存在噪声的情况下，测量纯音和语音（单个单词）的ITD检测阈值。据预测，与音调相比，由于信息在频率上的冗余，语音听力损失的影响会减少。总的来说，阈值更好，听力损失的影响在言语方面比在音调方面更不明显。没有证据表明噪音会加重听力损失的影响。
Sensitivity to interaural time differences (ITDs) was measured in two groups of listeners, one with normal hearing and one with sensorineural hearing loss. ITD detection thresholds were measured for pure tones and for speech (a single word), in quiet and in the presence of noise. It was predicted that effects of hearing loss would be reduced for speech as compared to tones due to the redundancy of information across frequency. Thresholds were better overall, and the effects of hearing loss less pronounced, for speech than for tones. There was no evidence that effects of hearing loss were exacerbated in noise.
