作者调查了青藏高原4个输油泵站的噪声强度,对83名泵站工作人员的听力、血红蛋白及其他有关因素进行了测定,用多元逐步回归方法对高原噪声性聋的诸因素进行了分析,发现高原缺氧可促使噪声性聋的发生.诸因素中,噪声强度是主要因素,血红蛋白及吸烟与噪声性聋的患病率、听力损害程度呈正相关.认为高原缺氧可引起红细胞代偿性增多,吸烟可引起血液粘度增高,从而可能减少内耳血液供应,使其易受噪声损伤.
The authors investigated the noise intensity of four oil pumping stations on the Qinghai-Tibet Plateau, measured the hearing, hemoglobin and other related factors of 83 pumping station workers, and analyzed the factors of altitude noise-deafness using multiple stepwise regression. Found that the lack of oxygen can promote the occurrence of noise-induced deafness.Among the factors, the noise intensity is the main factor, the prevalence of hemoglobin and smoking and noise-induced deafness, the degree of hearing impairment is positively correlated.Human plateau hypoxia can cause red blood cell compensatory Increased, smoking can cause increased blood viscosity, which may reduce the blood supply to the inner ear, making it susceptible to noise damage.
