目的 了解铅和噪声联合作用对工人听力损伤的影响.方法 选择年龄、工龄及接触噪声强度相近的A组(铅和噪声联合作用组)、B组(单纯噪声组)两组工人,进行纯音听阈检测比较.结果 与B组工人相比,A组工人在4KHz、6KHz段听阈提高明显,差异有统计学意义(P＜0.05或P＜0.01).结论 铅和噪声联合作用对工人听力损伤有协同作用,可加重听力损伤.
目的 瞭解鉛和譟聲聯閤作用對工人聽力損傷的影響.方法 選擇年齡、工齡及接觸譟聲彊度相近的A組(鉛和譟聲聯閤作用組)、B組(單純譟聲組)兩組工人,進行純音聽閾檢測比較.結果 與B組工人相比,A組工人在4KHz、6KHz段聽閾提高明顯,差異有統計學意義(P＜0.05或P＜0.01).結論 鉛和譟聲聯閤作用對工人聽力損傷有協同作用,可加重聽力損傷.
목적 료해연화조성연합작용대공인은력손상적영향.방법 선택년령、공령급접촉조성강도상근적A조(연화조성연합작용조)、B조(단순조성조)량조공인,진행순음은역검측비교.결과 여B조공인상비,A조공인재4KHz、6KHz단은역제고명현,차이유통계학의의(P＜0.05혹P＜0.01).결론 연화조성연합작용대공인은력손상유협동작용,가가중은력손상.
Objective To explore the combined effects of lead and noise exposure on hearing impairment in workers, Methods The workers with matched age, length of working, and intensity of noise were chosen to group A (lead and noise exposure) or group B (noise exposure alone). The hearing ability was detected and compared in the two groups. Results As compared with group B, the threshold of hearing increased obviously in group A at 4 KHz and 6 KHz. Conclusions Lead plus niose exposure may worsen the hearing impairment.
