我国有关职业噪声聋诊断标准各地区掌握的标准不一。上海市卫生局已于1982年颁布试行“职业噪声聋诊断标准。我们对典型病例的诊断进行探讨,以供制订全国性的诊断标准时参考。测听方法对纺织厂未曾接触过职业噪声的新工人,询问耳科病史,进行工作前体检和测听。接触噪声作业6年后,于脱离噪声24小时,再在本底噪声小于40dB(A)的活动隔音室内,使用经国家计量单位校验的Z-1B阳Danplex电子听力仪,用Madsen73A型声阻抗仪测定镫骨肌反射阅,用Madsen2250测定诱发脑干电位。用ND_2型精密声级计测定纺织厂织
Our country occupational noise deaf diagnostic standards in different regions have different standards. The Shanghai Municipal Health Bureau promulgated a pilot program entitled “Diagnostic criteria for deafness of occupational noise in 1982. We discuss the diagnosis of typical cases for reference when formulating national diagnostic criteria.” Listening method New workers who have not been exposed to occupational noise in textile mills , Ask the history of otology, physical examination and audiometry before work.After 6 years of exposure to noise operation, at 24 hours after leaving the noise, and then in the noise floor with noise floor less than 40dB (A) Z-1B Yang Danplex electronic audiometer, with Madsen73A acoustic impedance meter measured stapedius reflexes, measured by the Madsen2250 induced brain stem potential. With the ND2-type precision sound level meter to determine the textile mill
