Hearing disorders are common among music professionals, as they are frequently exposed to sound levels exceeding 100 dB(A). By assessing auditory fatigue, situations that are deleterious for hearing could be identified, allowing the deployment of preventive measures before permanent impairment occurs. However, little is known about the factors contributing to auditory fatigue. The objective is to determine the exposure parameters most influencing auditory fatigue during occupational exposure to amplified music.
Auditory fatigue was defined as variations of both pure tone auditory (ΔPTA) and efferent reflex thresholds (ΔER) during the workday. Noise exposure was monitored and information on the volunteers was gathered using a questionnaire.
The population consisted of 43 adult volunteers exposed to amplified music (sound, light or stage technicians, security agents, barmen) and 24 unexposed administrative agents.
ΔPTA and ΔER were positively correlated with the energy of noise exposure and its stability over time, a steady noise tends to create more auditory fatigue.
In addition to a global decrease of music levels and a systematic use of hearing protection, our results advocate for the provision of quiet periods within noise exposures as they reduce auditory fatigue accumulation and long-term risks for hearing.
音乐专业人员中听力障碍较为常见，因为他们经常暴露在超过 100dB(A)的声级环境中。通过评估听觉疲劳，可以确定对听力有害的情况，从而在永久性损伤发生之前采取预防措施。然而，对于导致听觉疲劳的因素知之甚少。本研究旨在确定在职业性接触放大音乐时，最能影响听觉疲劳的暴露参数。
听觉疲劳被定义为工作日期间纯音听阈（ΔPTA）和传出反射阈值（ΔER）的变化。通过监测噪声暴露，并使用问卷收集志愿者的信息来评估听觉疲劳。
该人群包括 43 名接触放大音乐的成年志愿者（音响、灯光或舞台技术员、安全人员、调酒师）和 24 名未接触音乐的行政人员。
ΔPTA 和 ΔER 与噪声暴露的能量及其随时间的稳定性呈正相关，稳定的噪声往往会导致更多的听觉疲劳。
除了全面降低音乐音量和系统使用听力保护装置外，我们的研究结果还提倡在噪声暴露期间提供安静时段，因为这可以减少听觉疲劳的积累和长期听力风险。
