[目的]探讨电厂噪声对作业人员身体健康的影响。[方法]选择62名运行工为观察组,另选该厂非运行工声60名作业人员为对照组。检测两组作业人员环境噪声强度,观察组40h的等效声级为84dB(A),对照组为65dB(A)。询问临床症状,测定心电图、血压、肝功、血常规、小便常规及作B超、胸片检查。[结果]两组作业环境噪声强度均未超过职业接触限值。观察组头晕头痛、失眠多梦、心悸胸闷、耳鸣、心电图异常率、ST-改变,血压偏高明显高于对照组(P﹤0.01),其他指标两组间比较差异不明显(P﹥0.05)。[结论]结果提示在现场噪声强度未超过职业接触限值的情况下,作业人员的身体健康已受到一定影响,建议运行工在巡视时应佩戴防噪声用品,以保护身体健康。
[Objective] The research aimed to discuss the impact of plant noise on the health of workers. [Method] Sixty-two operation workers were chosen as the observation group, and 60 non-operation workers were selected as the control group. The ambient noise intensity of the two groups of workers was detected. The equivalent sound level at 40h in the observation group was 84dB (A) and that in the control group was 65dB (A). Ask clinical symptoms, determination of ECG, blood pressure, liver function, blood, urine and conventional B ultrasound, chest X-ray examination. [Results] The noise intensity of operating environment did not exceed the occupational exposure limit. The observation group had dizziness and headache, insomnia and more dreams, palpitations and chest distress, tinnitus, abnormal ECG rate, ST-change and high blood pressure were significantly higher in the observation group than in the control group (P <0.01) . [Conclusion] The results suggest that the physical health of workers has been affected to a certain extent when the on-site noise intensity does not exceed the occupational exposure limit. It is recommended that operators should wear anti-noise products to protect their health during the inspection.
