| 摘 要： | 目的为探讨高温与噪声联合作用对作业工人听力的影响。方法联合作用组(A组)67名，单纯噪声组(B组)56名，对照组54名(C组)进行听力损伤的调查。结果噪声强度A组LAeq87．4dB(A)，B组LAeq87．0dB(A)；各组听损发生率A组＞B组＞C组，组间比较(P＜0．01)；各组间不同频率的听阈均值对比中，2、3、4、6kHz以A组＞B组＞C组，各组间比较(P＜0．01)。结论提示高温与噪声对工人高频听阈有协同作用。

| Abstract: | Objective To investigate the combined effects of high temperature and noise on hearing of the exposed workers.Methods The hearing of three groups of workers was determined, including 67 male workers in group A who were exposed to both high temperature and noise, 56 men in group B who were exposed to only noise and 54 men in group C as control.Results The noise intensity was 87 4 dB(A) in group A and 87 0 dB(A) in group B. The incidence of hearing loss appeared to be successively increasing in the order of group A, B and C ( P <0 01 each other). The thresholds of audibility on 2,3,4 and 6 kHz was successively decreased in group A, B and C ( P <0 01 each other).Conclusion It indicated that three might be a combined effect of high temperature and noise on the hearing loss. |
