Out of data on 25,544 workers exposed to noise three groups of the same age and of equally high exposure are selected, which serve to study the effects of the varying periods of noise exposure. A regression-analysis is made for both men and women in each group. Due to the method of analysis chosen the ascent of the regression-line (regression-coefficient) represents exclusively the effects of noise-exposure on the loss of hearing. The regression-coefficients for men and women turn out to be the same. Thus, contrary to previous studies, there is no difference between men and women in the effects of occupational noise-exposure on the ability to hear. The fact that male workers exposed to noise suffer usually from a more deteriorated sense of hearing than female workers can be explained by the increased effects of presbyacusis.
在25544名接触噪音的工人的数据中，选取了三组年龄相同且接触程度同样高的工人，用于研究不同噪音接触时长的影响。对每组中的男性和女性都进行了回归分析。由于所选用的分析方法，回归线的上升（回归系数）仅代表噪音接触对听力损失的影响。结果发现男性和女性的回归系数相同。因此，与之前的研究相反，职业噪音接触对听力的影响在男性和女性之间没有差异。接触噪音的男性工人听力通常比女性工人更差这一事实，可以用老年性耳聋影响的增加来解释。
