目的比较和观察噪声对作业人员健康的影响,为进一步改善卫生防护措施提供科学依据。方法选择某五金厂噪声作业人员205人为观察组,选择同厂非噪声作业人员214人为对照组,进行心电图、血压和听力检查,同时测量工作场所噪声强度。结果噪声作业人员心电图异常率、高血压患病率、听力异常率分别为11.2%、13.6%、15.6%,与对照组3.7%、2.3%、0%相比均有显著性差异(P<0.01)。结论长期接触噪声不仅损伤听力,同时还对心血管系统造成不利的影响。
Objective To compare and observe the impact of noise on the health of workers and provide a scientific basis for further improvement of health protection measures. Methods A total of 205 noise workers in a metal factory were selected as the observation group. 214 non-noise workers were selected as the control group, and the electrocardiogram, blood pressure and hearing tests were performed, and the noise intensity in the workplace was measured. Results The abnormal rate of electrocardiogram, the prevalence of hypertension and the rate of abnormal hearing were 11.2%, 13.6% and 15.6% respectively in noise workers, which were significantly different from those in control group (3.7%, 2.3%, 0%) ). Conclusion Long-term exposure to noise not only damages hearing, but also adversely affects the cardiovascular system.
