摘　　要：目的探讨火力发电厂噪声对作业工人听力的影响。方法对某火力发电厂509名噪声作业人员进行横断面调查,并将听力损失与工龄、工种、年龄进行统计学分析。结果509名噪声作业人员中噪声性听力损伤8人,轻、中度听力损伤及噪声聋12人,检出率为3.9%。不同工龄组间(χ2=7.7,P<0.05),不同工种之间(χ2=6.17,P<0.05)听力损失有统计学意义,女性工作人员176名未检出听力损伤。结论火力发电厂噪声致噪声性听力损伤与其工种及工龄有关,与性别无关。Objective To discuss the effect of noise on hearing loss to the power plant workers. Method Crosssectional study was conducted to survey 509 thermal power plant workers exposed to noise. And the correlation between hearing loss and seniority, type of work, age was statistically. Result The result showed that 8 workers were the noise-induced hearing loss and 12 workers were mild hearing loss and noise deaf. The incidence rate was 3.9%. The hearing lose among different seniority groups （X2 =7.7, P 〈0. 05）, and different types of work （ X2 = 6.17, P 〈 0.05） had differences. But the women there was no hearing lose. Conclusion Thermal power plant noise leads to noise-induced hearing loss which related to their type of work and seniority, hut unrelated to sex.
