为寻求控制治理噪声的科学依据,我们对合肥和淮南市的纺织、机械、印刷、钢铁、化工、电子、建工建材等八个行业150多个工广进行了噪声概况调查。选择其中26个工厂接触80～115d B(A)稳态噪声的工人2014名进行体检,其工龄在半年以上,年龄在50岁以下,作为观察组。同时选择了性别、年龄相仿、劳动强度相近,接触噪声在70dB(A)以下的232名工人为对照组。 In order to find a scientific basis for the control of noise, we conducted a noise survey of more than 150 workers in eight industries including textile, machinery, printing, steel, chemicals, electronics, construction materials and building materials in Hefei and Huainan. A total of 26 workers were interviewed in 2014 for physical examination of 80 ~ 115d B (A) steady-state noises. The workers were over half a year old and under the age of 50 as observation group. At the same time, 232 workers whose sex, age are similar, labor intensity is similar, and the contact noise is under 70dB (A) are selected as the control group.
