本文采用剂量患病率寿命表法对某铝矿２９０名接噪作业工人噪声性耳聋的发病情况作了相关回归分析。结果为该铝矿接噪工人噪声性耳聋的总患病率为１４．２８％，且噪声聋患病率随累积接噪量的增加而升高，呈明显正相关（ｒ＝０．９９７５，Ｐ＜０．０１）。并据所求得的回归方程（Ｐ＝５．０４６０ＩｎＤ－２０．６９４６）推算出了接噪工人控制某患病率时的允许连续工作年限和今后的发病趋势。为加强铝矿作业噪声治理和噪声聋防治提供了依据。
In this paper, the use of dose rate of life table method to 290 workers exposed to noise of an aluminum mine workers noise-related deafness incidence regression analysis. The result showed that the total prevalence of noise-induced deafness was 14.28% in noise-exposed workers, and the prevalence of noise-deafness was positively correlated with the increase of accumulated noise (r = 0.9975, P <0.01). According to the obtained regression equation (P = 5.0460InD-20.6946), the allowable continuous working years and the future trend of incidence when the noise worker controlled a certain prevalence rate were calculated. It provides the basis for strengthening the noise management and noise and deaf prevention in the operation of aluminum mine.
