为了解乡镇工业的职业危害,我们于1985和1987年对某村办制钉厂噪声对工人健康影响进行了调查。调查内容包括:一般情况、噪声测定、工人健康检查等。一、制钉车间噪声测定结果如表1。所用仪器为ND_2型精密声级计和倍频程滤波器。制钉车间工人在95～105dB环境中每天纯工作8小时,两年来噪声环境未改变。第一次检查工人普遍反应头昏、耳鸣、听力下降、记忆力减退。第二次检查,上述症状又有加重。二、听力检查,查制钉车间15名工人。平均工 In order to understand the occupational hazards of township industries, we conducted a survey in 1985 and 1987 on the health effects of noise from nailing factories at a village. The survey includes: general situation, noise measurement, worker health examination and so on. First, the nail workshop noise measurement results in Table 1. The instruments used are type ND 2 precision sound level meters and octave filters. Stapler workshop workers in the 95 ~ 105dB environment pure work 8 hours a day, two years the noise environment has not changed. The first inspection workers generally dizziness, tinnitus, hearing loss, memory loss. The second check, the above symptoms have aggravated. Second, hearing tests, check the nail workshop 15 workers.
