目的了解噪声对冶金设备厂作业工人听力的影响。方法选取115名噪声作业工人为调查组,行政和后勤人员93名为对照组,对两组人员的听力情况进行调查分析。结果调查组的听力损失为20.0%,明显高于对照组的7.52%,差异有统计学意义(χ2=6.48,P<0.01),并且听力损失随着接触噪声工龄的增加而增加。结论噪声对常熟市冶金设备厂作业工人听力存在影响。
Objective To understand the effect of noise on hearing of workers in metallurgical equipment factory. Methods A total of 115 noise workers were selected as survey group and 93 administrative and logistics staff as control group. The hearing conditions of the two groups were investigated. Results The hearing loss of the surveyed group was 20.0%, which was significantly higher than that of the control group (7.52%) (χ2 = 6.48, P <0.01), and the hearing loss increased with the increase of exposure to noise. Conclusion The noise affects the hearing ability of workers in Changshu Metallurgical Equipment Factory.
