【摘要】：目的对无自觉症状噪声暴露作业者进行了常频与高频测试检查,以期发现隐性噪声性听力损害情况,并连续观察噪声对听力损害变化特点。方法对86例(172耳)(0.25~8 k Hz)无自觉症状噪声作业者(噪声暴露组)和对照组10例(20耳),进行气导听阈值测定,分别对常频(0.25~2 k Hz)和高频(3~8 k Hz)气导平均阈值情况进行对比分析,并且连续随访3年。结果与对照组比较噪声暴露组常频段听阈差异无统计学意义(P0.05),高频平均阈值均高于对照组,差异有统计学意义(P0.01);随访3年,每年高频异常耳比例虽增多,但期间听力损害程度加重不明显(P0.05)。结论噪声暴露可使得高频听力损害,但是受损的高频听力损害进程缓慢。
[Abstract]:Objective to detect the hearing impairment caused by hidden noise in the workers exposed to noise without conscious symptoms, and to observe the characteristics of hearing impairment caused by noise continuously.Methods 86 cases of noise workers (noise exposure group) without conscious symptoms (noise exposure group) and 10 cases of control group (control group) were measured the threshold of air-conduction hearing, and the mean threshold of air-conduction was compared with that of normal frequency 0.252kHz and high-frequency 3kHz, respectively, and compared with that of the control group (n = 10), and compared with that of the control group (n = 10, n = 10, n = 10, n = 10, n = 10, n = 10, n = 10, n = 10).The patients were followed up for 3 years.Results compared with the control group, the hearing threshold of the noise exposure group was not significantly different from that of the control group (P 0.05), the mean threshold of high frequency was higher than that of the control group, and the difference was statistically significant (P 0.01), followed up for 3 years, the proportion of abnormal ears with high frequency increased every year.However, the severity of hearing impairment was not obvious (P 0.05).Conclusion noise exposure may lead to high frequency hearing impairment, but the process of high frequency hearing impairment is slow.
