Many amateur musicians are likely to be exposed to high sound levels during rehearsals. Measuring otoacoustic emissions (OAE) is an objective technique to assess hearing ability and can be used as an early predictor of hearing loss. This study aimed to record sound levels at an amateur brass band rehearsal and to examine the cochlear function of the musicians by evaluating distortion product (DP) OAE amplitudes before and after sound exposure. Twenty-four brass band musicians and 10 office workers were examined with personal noise measurements and DPOAE tests before and after a music rehearsal or one office workday, respectively. The sound levels in the brass band ranged from 92 to 100 dBA, LaEQ 96 dBA. However, the amateur brass band members had no change in DPOAEs after this exposure compared to pre-exposure levels and compared to office workers.
许多业余音乐家在排练期间可能会暴露于高强度声音环境中。测量耳声发射（OAE）是一种评估听力能力的客观技术，可作为听力损失的早期预测指标。本研究旨在记录一支业余铜管乐队排练时的声音水平，并通过评估声音暴露前后的畸变产物（DP）耳声发射幅度来检查音乐家的耳蜗功能。分别在一次音乐排练或一个工作日前后，对24名铜管乐队音乐家和10名办公室职员进行了个人噪声测量和DPOAE测试。铜管乐队中的声音水平范围为92至100 dBA，等效连续A声级（LaEQ）为96 dBA。然而，与暴露前水平以及与办公室职员相比，这些业余铜管乐队成员在此次暴露后DPOAE没有变化。
