我们于1992年对连云港港务局轮驳公司接触噪声的110名船员进行听力普查,并对获得的资料进行分析,初步探讨噪声性聋的诊断、听力图类型以及噪声接触时间长短与噪声性聋的关系等问题.资料和方法 首先测得轮驳机舱噪声强度为102～110dB.测试对象为有噪声暴露史的轮驳机舱船员,均为男性,年龄分布为:18～25岁 39名,26～35岁18名,36～45岁47名,46岁以上6名.按噪声暴露时间长短,可分为:不足1年25名,1～5年9名,6～10年12名,11～15年34名,16～20年23名,21年以上7名.测试方法为受试者由耳鼻喉科医师作耳部(包括耳道、鼓膜及乳突情况)检查,并由有经验的检测人员在测听室用日本
In 1992, we carried out a hearing survey of 110 crew members who came into contact with the company from Lianyungang Port Authority and conducted an analysis of the obtained data to initially discuss the diagnosis of noise-induced deafness, the type of audiogram, the length of noise exposure and the noise-induced deafness Relationship and so on.Materials and Methods Firstly, the noise intensity of the barge cabin was measured to be 102 ~ 110dB.The test object was a barge cabin crew with a history of noise exposure, all of them were male, the age distribution was: 39 aged from 18 to 25, 35 years old 18, 36 to 45 years old 47, 46 years old 6. According to the length of noise exposure, can be divided into: less than 1 year 25, 1 to 5 years 9, 6 to 10 years 12, 11 ~ 15 years 34, 16-20 years 23, more than 21 years 7. Test method for the subjects by the otolaryngologist for the ear (including the ear canal, tympanic membrane and papillae situation) check, and by the experienced Detector in the audiometry room with Japan
