Musicians and dancers can be considered an at-risk population for developing noise-induced hearing loss.
To determine the audiological profile of members of a folklore-related music group and quantify noise exposure at their rehearsal venue.
This was a quantitative and descriptive study. The musicians and dancers were evaluated in two stages: an interview about their working life, followed by high frequency tonal audiometry. The sound pressure level in the group's rehearsal venue was measured using a BEK 2270 Noise Analyzer.
A total of 7.2% of the subjects had noise-induced hearing loss (NIHL) and 39% of the audiometric tests were notch type. During the interview 31.7% of the subjects mentioned discomfort from loud noise, although none of them used ear protection. The environmental assessment showed inadequate humidity and oscillating temperature. Twenty sound pressure level measurements were performed for Leq (equivalent sound pressure levels) and the results ranged from 88 dB (A) to 99 dB (A) with a mean of 97.05.
Exposure to high levels of sound pressure has led to NIHL in some members of the group. Some of those with normal hearing also presented a notch configuration characteristic of NIHL. Tinnitus, indicating that a change in hearing has occurred, was the most frequent auditory symptom.
音乐家和舞蹈家可能被视为易患噪声性听力损失的高危人群。
确定与民俗音乐相关的音乐团体成员的听力学特征,并量化其排练场地的噪声暴露情况。
这是一项定量和描述性研究。音乐家和舞蹈家分两个阶段进行评估:一是关于其工作生活的访谈,二是高频音调听力测试。使用 BEK 2270 噪声分析仪测量团体排练场地的声压级。
共有 7.2%的受试者出现噪声性听力损失(NIHL),39%的听力测试为凹陷型。在访谈中,31.7%的受试者提到对强噪声的不适,但他们都没有使用耳塞。环境评估显示湿度和温度波动不足。对 Leq(等效声压级)进行了 20 次声压级测量,结果范围在 88 dB(A)至 99 dB(A)之间,平均值为 97.05。
高强度的声压暴露导致了团体中一些成员的 NIHL。一些听力正常的人也出现了 NIHL 的凹陷型特征。耳鸣是最常见的听觉症状,表明听力已经发生变化。
