This study describes the prevalence and characteristics of noise-induced hearing loss (NIHL) in student musicians (N = 329) aged 18-25 years. Students completed a questionnaire regarding exposures before a hearing assessment. NIHL was defined by the presence of a notch 15 dB in depth at 4000 or 6000 Hz relative to the best preceding threshold. Overall prevalence of NIHL was 45%, with 78% of notches occurring at 6000 Hz. The proportion of the total population with bilateral notching at any frequency was 11.5%, mostly occurring at 6000 Hz. There was a significant increase in the frequency of notching in students who reported more than two hours per day of personal practice. There were no significant associations for instrument group or other noise exposures. The data suggest that susceptibility to NIHL among students of music is not uniform and cannot be ascribed solely to the instrument played and other exposures. Students with bilateral losses tend to have deeper notches and may represent a group that has an inherent predisposition to NIHL.
本研究描述了 18-25 岁学生音乐家（N=329）中噪声性听力损失（NIHL）的流行率和特征。学生们在听力评估前完成了一份关于暴露情况的问卷。NIHL 的定义是在 4000 或 6000 Hz 处相对于先前最佳阈值出现 15 dB 深度的凹陷。NIHL 的总体患病率为 45%，其中 78%的凹陷发生在 6000 Hz。在任何频率双侧出现凹陷的总人群比例为 11.5%，主要发生在 6000 Hz。报告每天个人练习超过两小时的学生出现凹陷的频率显著增加。乐器组或其他噪声暴露与凹陷无显著相关性。这些数据表明，音乐学生对 NIHL 的易感性并不一致，不能仅归因于所演奏的乐器和其他暴露。双侧听力损失的学生凹陷较深，可能代表着一组对 NIHL 具有内在易感性的人群。
