We measured noise exposure and temporary threshold shift (TTS) from a rock concert for 22 volunteers, using dosimetry, questionnaires, and audiometry. Most (81%) participants showed TTS of 10 dB or more 5 to 25 minutes after exposure; of these, 76% showed continued TTS at 40 to 60 minutes. Family physicians should counsel patients about the risks of recreational noise.
我们使用剂量测定法、问卷调查和听力测定法,对22名志愿者在一场摇滚音乐会中的噪声暴露情况和暂时性阈移(TTS)进行了测量。大多数(81%)参与者在暴露后5至25分钟出现了10分贝或更高的暂时性阈移;其中,76%的人在40至60分钟时仍有持续的暂时性阈移。家庭医生应向患者提供有关娱乐性噪声风险的咨询。
