随着工业和运输业的快速发展,噪声已成为影响人耳听力功能的高危因素,由职业性噪声导致的噪声性听力损失(Noise-induced hearing loss,NIHL)是继老年性听力损失之后第二常见的感音神经性听力损伤~([1])。NIHL是指劳动者长期接触工作场所中的噪声而发生的一种渐进性的感音性听觉损伤~([2])。尽管环境因素在NIHL的发生过程中起着重要作用,但越来越多的研究表明,在相同的噪声水平环境下接触相同的时间,排除其他混杂因素的影响,不同个体发生听 With the rapid development of industry and transportation, noise has become a risk factor affecting the hearing function of the human ear. Noise-induced hearing loss (NIHL) is the second most common cause of senile hearing loss Common sensorineural hearing loss ~ ([1]). NIHL refers to a progressive sensory hearing impairment that occurs when workers are exposed to prolonged workplace noise (2). Although environmental factors play an important role in the development of NIHL, more and more studies show that exposure to the same time in the same noise level environment, excluding the influence of other confounding factors, the occurrence of different individuals
