摘要
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 noise intensity at petroleum transport pump stations on Qinghai-Xizang plateau was surveyed. The hearing, hemoglobin and other related factors of 83 pump workers were investigated and analysed using multiple stepwise regression analysis. The results showed that the oxygen deficiency on plateau may impel the noise deafness. The noise intensity is the main factor of noise deafness. Hemoglobin concentration and smoking are positively correlated with the morbidity and the degree of hearing loss. It is considered that plateau oxygen deficiency may lead to erythrocyte increase, and smoking the increase of blood viscosity, thereby, the blood supply of inner ear is decreased, and the damage of inner car by noise aggravated.
