Temporary threshold shift (TTS) was studied in pop musicians as well as in listeners. It appears that TTS is less pronounced in pop musicians than in listeners. This can only in part be explained by slightly inferior hearing threshold levels than in the audience before exposure. Further, male listeners showed more TTS than female listeners. After 2 hours of exposure to live pop music a TTS2 appears in pop musicians after an exposure to 98 dB(A) as opposed to listeners where TTS2 appears at 92 dB(A). When the present results are related to the CHABA risk criteria it seems that exposure to live pop music at 100 dB(A) for 2 hours is a limit which should not be exceeded if the risk of permanent hearing loss is to be avoided.
研究了流行音乐家以及听众的暂时性阈移（TTS）。结果显示，流行音乐家的TTS不如听众明显。这只能部分解释为他们暴露前的听力阈值水平略低于观众。此外，男性听众的TTS比女性听众更明显。在暴露于现场流行音乐2小时后，流行音乐家在暴露于98分贝（A）后会出现TTS2，而听众在92分贝（A）时就会出现TTS2。当将目前的结果与CHABA风险标准相关联时，似乎如果要避免永久性听力损失的风险，那么暴露于100分贝（A）的现场流行音乐2小时是一个不应超过的限度。
