Abstract

The induced reduction in the loudness (ILR) of a weaker tone caused by a preceding stronger tone was measured with both tones in the same ear (ipsilateral ILR) and also in opposite ears (contralateral ILR). The two tones were always equal in duration and were presented repeatedly over several minutes. When the tone duration was 200 ms, for 24 listeners the loudness reduction averaged 11 dB under ipsilateral ILR and 6 dB under contralateral ILR. When the duration was 5 ms, ILR was 8 dB whether ipsilateral or contralateral. For each duration, ipsilateral and contralateral ILR were strongly correlated (r around 0.80).

摘要

由先前较强的音调引起的较弱音调的响度降低（ILR），通过在同一耳（同侧ILR）以及对侧耳（对侧ILR）中测量两个音调来进行评估。两个音调的持续时间始终相等，并在几分钟内反复呈现。当音调持续时间为200毫秒时，对于24名听众，同侧ILR下的响度降低平均为11分贝，对侧ILR下为6分贝。当持续时间为5毫秒时，同侧或对侧的ILR均为8分贝。对于每个持续时间，同侧和对侧ILR都具有很强的相关性（r约为0.80）。
