目的了解电子封装企业噪声作业工人听力损伤情况。方法选择某电子封装企业接触噪声作业人员404人为接触组,该企业后勤和行政工作人员93人为对照组,结合年龄、接触噪声工龄、性别,对两组听力损伤情况进行比较分析。结果接触组听力损伤检出率为16.58%,高于对照组,差异有统计学意义(χ~2=9.315,P<0.01);且听力损伤率随接触噪声工龄的增加而升高;男性工人听力损伤检出率要高于女性,差异有统计学意义(χ~2=4.534,P<0.05)。结论电子封装企业噪声作业工人的听力损伤情况不容乐观,应引起足够重视。
Objective To understand the hearing impairment of noise workers in electronic packaging enterprises. Methods A total of 404 contact noise workers in an electronic packaging company were selected as the contact group. Ninety-three control and management staff members of the enterprise were selected as the control group. The age, exposure duration and gender of the noise were compared and analyzed. Results The detection rate of hearing loss in the contact group was 16.58%, which was higher than that in the control group (χ ~ 2 = 9.315, P <0.01). And the rate of hearing impairment increased with the increase of the contact noise. Male workers The detection rate of hearing impairment was higher than that of women, the difference was statistically significant (χ ~ 2 = 4.534, P <0.05). Conclusion Hearing impairment of noise workers in electronic packaging enterprises is not optimistic, which should be paid enough attention.
