摘　　要：目的通过对某铝冶炼生产过程中噪声危害的识别与分析,找出噪声危害的关键控制点。方法现场调查与检测。结果该厂职工有5044人,累计职业噪声耳聋14例,患病率达0.3%。电解车间的球磨机、鄂式破碎机、硅石振动筛、型材切割机、空压机等为关键控制点。结论铝冶炼生产中噪声危害的防护应从关键控制点入手,使噪声声级控制在国家职业卫生限值以下。Objective To Analyze the hazards of noise in the aluminum metallurgical industry,find out the key control point and control level Methods Field investigate and detection were applied. Results 14 cases caused occupational noise deaf ,occupied 0. 3% of 5 044 workers. Some posts were confirmed the key control point. Conclusion Noise hazard protection in the aluminum metallurgical industry should be strengthened from the key control point.
