本文作者为修正工业企业工人操作地带的噪声标准,重点研究了稳态和脉冲噪声对中枢神经系统的影响。调查接触宽带高频稳态噪声(90～100分贝A)工人256名及接触脉冲高频噪声(107～117分贝A)284名工人,两组中的等量水平噪声为95分贝(A)。第Ⅰ组成员为钳工、车工及耕作者,第Ⅱ组为自动机械工、雪茄烟切边工、压榨机操作工。两组成员的年龄、性别、工龄等基本一致。其中60%的工人为25～45岁,工龄一般在10年以上。第Ⅰ组女工占39%,第Ⅱ组
In order to correct the noise level of workers in industrial enterprises, the author focuses on the effects of steady-state and impulse noise on the central nervous system. A total of 256 workers exposed to broadband high-frequency steady-state noise (90 to 100 dB A) and 284 workers exposed to pulsed HF noise (107 to 117 dB A) were surveyed and their equivalent level noise was 95 dB (A). The first group of members for fitter, lathe and cultivator, the second group of automatic mechanics, cigar trimming, press operator. Two groups of members of the age, gender, length of service basically the same. 60% of workers are 25-45 years old and the general working length is over 10 years. Women in Group I accounted for 39%, Group II
