摘要
目的了解中国民航飞行员听力状况在一定时间内的变化趋势。方法将185名民航飞行员按照初访时年龄分为A(20~岁,101人)、B(30~岁,49人)、C(40~49岁,35人)三组,分别测试其纯音听阈,10年后随访复查纯音听阈,比较随访前后各组听力损失发生率及纯音听阈变化情况。结果 185名飞行员中共有126名随访成功,随访率为68.11%(126/185)。126名飞行员初访及随访时语频听力损失发生率分别为0.79%(1/126)和4.76%(6/126),高频听力损失发生率分别为14.29%(18/126)和30.95%(39/126),随访时听力损失发生率显著高于初访时(P<0.05);各年龄组10年后随访时的纯音听阈较初访时明显提高(P<0.01),且高频较语频提高明显(P<0.05),经年龄修正后,仅A组10年后测得的纯音听阈明显高于初访时(P<0.01),其它年龄组差异无显著统计学意义。结论民航飞行员听力损失的发生和发展以高频为主,进而影响语频,主要与噪声和年龄因素有关。
