对接触噪声作业工人进行听力测试,并对测试结果进行分析。根据GB/T16403-1996《声学测听方法纯音气导和骨导听阈基本测听法》进行纯音听阈测定。结果显示,共完成体检12 073人,其中高频检出异常为5 785人,高频平均听阈≥40 dB的为989人。提示,企业规模越大,体检率越高,各项异常率越低;不同经济类型,体检率和异常率存在差异;接触噪声的工龄越长,其各项的异常率也越高。
Hearing tests were conducted on workers exposed to noise and the test results were analyzed. According to GB / T16403-1996 “acoustic audiometry and pure bone conduction guide audiometry threshold audiometry” pure tone audiometry. The results showed that a total of 12 073 medical examinations were completed, of which 5 785 were detected abnormally at high frequency and 989 were high-frequency average hearing threshold ≧ 40 dB. Prompt, the larger the scale of enterprises, the higher the physical examination rate, the lower the rate of abnormalities; different economic types, physical examination rates and abnormal rates are different; the longer the length of exposure to noise, the higher the abnormal rate.
