摘　　要：为防治职业噪声源对消防员早期听力损失,开展消防员职业接触噪声检测,评估消防员听力损失程度,量化消防员听力损失比率,进一步分析消防员听力检测结果与职业噪声暴露关系。结果表明:消防员接触的噪声强度超过作业场所噪声等级接触限值85 dB(A);对50名消防员的听力筛查结果中,噪声暴露后畸变耳声发射(DPOAE)听力筛查双耳未通过人数21人,占比为42.0%,通过率较正常人明显降低;纯音测听左/右耳听阈≥26 dB人数在6 kHz最多,人数在15和13时,占比为30.0%、26.0%;消防员职业噪声暴露高频环境中,听力损失明显。To prevent and treat the early hearing loss of firefighters caused by occupational noise sources,the occupational noise exposure detection for firefighters was conducted,and the degree of hearing loss in firefighters was evaluated.The ratio of hearing loss in firefighters was quantified,and the relationship between the hearing test results of firefighters and occupational noise exposure was analyzed.The results indicate that the intensity of the noise source for firefighters exceeds the exposure limit of noise levels in the workplace of 85 dB(A).Among the hearing screening results of 50 firefighters,the number of people who falisd the distortion product otoacoustic emission hearing screening in both ears is 21,accounting for 42.0%,and the pass rate is significantly lower than that of normal individuals.The number of people with left/right ear pure tone audiometry hearing thresholds≥26 dB is the greatest at 6 kHz,accounting for 30.0%and 26.0%at n=15 and n=13,respectively,suggesting high-frequency hearing loss in firefighters after occupational noise exposure.
