为了了解船员的听力情况 ,对 40 47名船员听力进行检测分析。结果 :甲板组 2 12 6人与机舱组 192 1人中 ,听力障碍总发生率、感音神经性聋发生率、高频听损程度、语频听损程度均无明显差别 (P >0 .0 5 )。但在不同年龄组之间随着年龄增加出现明显差别 ,(P <0 .0 0 5 )。提示 :①甲板组与机舱组船员在听力受损程度无差异 ,考虑除机舱噪音外 ,汽笛噪声亦可能是引起船员噪音性聋的原因 ;②船员的噪音性聋与工作年限呈正相关 ,且以高频听损为主
In order to understand the hearing of the crew members, 40 47 crew members were tested for hearing analysis. Results: There were no significant differences in the frequency of hearing loss between 2 12 6 persons in deck group and 192 1 persons in cabin group, the total incidence of hearing impairment, the incidence of sensorineural deafness, high frequency hearing impairment and audio frequency hearing loss. 0 5). However, there was a significant difference between different age groups with age (P <0.05). Hint: (1) There is no difference in hearing impairment among deck crew and cabin crew. In addition to cabin noise, siren noise may also cause noise deafness of crew. (2) Crew noise deafness and working life are positively correlated with High-frequency hearing loss based
