摘要
目的 建立歼击机飞行员听力档案 ,动态了解其听力状况。 方法 为改装体检的飞行员行纯音测试和声导抗检查 ,建立歼击机飞行员听力档案 ,并对其中的 32 0份资料进行分析。 结果 (1)计算听力图上 5 0 0、10 0 0、2 0 0 0、30 0 0Hz的平均气导听阈 ,32 0例的结果为左耳平均 13dBHL ,右耳平均 12dBHL。 (2 ) 32 0例中 4 1例 5 3耳有高频区听力损害。 (3) 314例6 0 0耳为A型曲线 ,10例 12耳为AD型曲线 ,2 2例 2 6耳为C型曲线 ,2例 2耳鼓膜小穿孔。 (4 ) 2 2例随访听力无变化。 结论 参与歼击机改装的飞行员的总体听力状况良好 ,但部分人员有高频区听力损害 ,2耳鼓膜小穿孔 ,今后应随访观察。建立歼击机飞行员的听力档案是十分必要的。
Objective To establish hearing files and investigate hearing condition for fighter pilot. Methods Pure tone test and acoustic immittance test were carried out for pilots who were under physical examination. 320 cases of them were analysed. Results (1) It was calculated that the mean of air conduction hearing threshold of 500、1000、2000、3000 Hz on audiogram. The mean of the left is 13 dBHL and the mean of the right ear is 12 dBHL. (2) 53 ears of 41 cases showed hearing loss on high frequency. (3)The function of eustachian tube showed type A curve in 600 ears of 314 cases,type AD curve in 12 ears of 10 cases and type C curve in 26 ears of 22 cases. There were small myringoruptures in 2 ears of 2 cases. (4) The hearing threshold did not change in 22 cases under follow-up. Conclusion Overall,hearing condition is well in fighter pilots who were under physical examination. But results of some pilots show hearing loss on high frequency and small myringoruptures,and they should be followed. Establishment of hearing files for fighter pilot is very necessary.
