Objective To follow up the hearing of newly enrolled students, inquire into the impact of high frequency hearing loss on linguistic frequency hearing and predict the change of hearing. Methods Newly enrolled student pilots from an Air Force flying college underwent estimation of hearing. The change of hearing among 16 student pilots with high frequency hearing loss on entrance was observed for 2 years. Results There was no significant change in the high frequency hearing loss among these students( H = 0). High frequency hearing loss had no impact on linguistic frequency hearing. Conclusions There are no significant changes in high frequency hearing loss over two years. There is no impact on linguistic frequency hearing.%目的 探讨一定程度高频听力损失的学员其听力变化情况及分析其对语频听力的影响,预判其变化趋势.方法 对某年入某航校的全部飞行学员2年后转校体检时进行听力学检测,对其中16名入校时即有高频听力损失学员的听力水平进行统计学分析.结果 入校时有高频听力损失的学员在2年后所有频率的听力改变差异均不具有统计学意义(H=0).结论 一定程度的高频听力损失2年后无明显进展趋势,对语频听力影响不显著.
