Objective: To assess the dose response relationship between the prevalence rate of noisedeafness and the noise exposure.
目的:探讨五金工业噪声性耳聋患病率与噪声接触剂量之间的关系。

The noise intensity is the main factor of noisedeafness. Hemoglobin concentration and smoking are positively correlated with the morbidity and the degree of hearing loss.
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。
