Otological and audiological evaluations were performed on 278 miners claiming compensation for noise-induced hearing loss (NIHL). Of the total sample, 28.7% had to be excluded as cases of nonmining NIHL. Of the cases of diagnosed as NIHL, approximately 50% showed an actual hearing impairment as based on a low fence of 25 dB for the average hearing levels at 0.5, 1, and 2 kHz, and 63% as based on the average hearing levels at 0.5, 1, 2, and 3 kHz for exposures of 15 to 49 years. No significant difference in NIHL was apparent except at 2 kHz between subjects exposed to intermittent vs intermittent-continuous noise. It was difficult to differentiate NIHL from sensorineural losses of other causes and impossible to apply an adequate correction factor for presbycusis.
对278名因噪声性听力损失（NIHL）而要求赔偿的矿工进行了耳科和听力学评估。在总样本中，28.7%因非采矿性NIHL病例而被排除。在被诊断为NIHL的病例中，约50%根据0.5、1和2kHz处平均听力水平的25dB低限显示出实际听力损害，而对于暴露15至49年的情况，根据0.5、1、2和3kHz处的平均听力水平，这一比例为63%。除了在2kHz处，暴露于间歇性噪声与间歇性-连续性噪声的受试者之间的NIHL没有明显差异。很难将NIHL与其他原因导致的感音神经性听力损失区分开来，也不可能对老年性聋应用适当的校正因子。
