Most studies of hearing loss prevention in the music industry focus on the risk of hearing injury to musicians. However, live-music sound engineers (LMSE) may also be at risk of hearing injury due to their work-related sound exposure. We studied 27 LMSE, all of whom underwent otologic examination, including audiometry, distortion product otoacoustic emissions, speech discrimination and uncomfortable loudness levels, and completed a questionnaire investigating their history of sound exposure and use of hearing protectors. Hearing thresholds were significantly poorer than normative data across several frequencies, and a substantial proportion reported constant tinnitus (30%) and reduced sound tolerance (41%). Use of hearing protection was relatively low, with many reporting interference with their job when using it. Our results suggest that LMSE are at risk of hearing injury due to their work-related sound exposure.
大多数音乐产业听力损失预防研究都集中在音乐家听力损伤的风险上。然而，由于工作相关的声音暴露，现场音乐音响工程师（LMSE）也可能有听力损伤的风险。我们研究了 27 名 LMSE，他们都接受了耳科学检查，包括听力测试、畸变产物耳声发射、语音辨别和不舒适响度级，并完成了一份调查他们的声音暴露史和使用听力保护器的问卷。在几个频率上，听力阈值明显比正常值差，很大一部分人报告说有持续的耳鸣（30%）和听力敏感度降低（41%）。听力保护器的使用相对较低，许多人报告说使用时会干扰他们的工作。我们的研究结果表明，LMSE 由于工作相关的声音暴露而有听力损伤的风险。
