In a longitudinal and an age cohort comparing study the influence of aging and occupational noise exposure on hearing sensitivity was studied. The participants of the longitudinal study were studied at 70, 75, and 79 years of age. Seventy year old men exposed to occupational noise had 10 to 15 dB poorer hearing in the high frequency range than nonexposed men. The difference in hearing acuity decreased with increasing age. The differences between exposed and nonexposed older persons was no longer significant at age 79. In women there were no differences in hearing sensitivity between those exposed to noise and those not exposed to noise. Men not exposed to noise had 10 to 15 dB poorer hearing at 4 kHz compared with women of the same age also not exposed to noise.
在一项纵向研究和一项年龄队列比较研究中，研究了衰老和职业噪声暴露对听力敏感性的影响。纵向研究的参与者在70岁、75岁和79岁时接受了研究。暴露于职业噪声的70岁男性在高频范围内的听力比未暴露的男性差10至15分贝。听力敏锐度的差异随着年龄的增长而减小。在79岁时，暴露组和未暴露组老年人之间的差异不再显著。在女性中，暴露于噪声和未暴露于噪声的人群在听力敏感性方面没有差异。与同样未暴露于噪声的同龄女性相比，未暴露于噪声的男性在4千赫时听力差10至15分贝。
