Risks to hearing from a rock concert.
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.
