摘　　要：目的探讨快速上浮脱险对潜艇艇员听力的影响。方法10名潜艇艇员分别进行了3、10、30、50m深度60人次模拟快速上浮脱险训练（3m和10m各2次）。训练前后检查潜艇艇员双侧鼓膜，并进行电测听检查。结果鼓膜未见异常，左耳在125、250Hz，双耳在500、2000Hz的听阈差异有统计学意义（P〈0．05）。结论快速上浮脱险时的气压快速改变对潜艇艇员的听力有一定的影响，以低频听阈降低为主要表现。Objective To study the effect of fast buoyancy ascent escape training on the hearing of submariners. Methods Simulated fast buoyancy ascent escapes at depths of 3, 10, 30 and 50 meters were carried out by 10 submariners, with a total of 60 man times （ at 3 and 10 m twice each depth）. Bilateral eardrum tests and electro -audiometry were performed both before and after escape training. Results No abnormality was found in the eardrums. Statistical differences in hearing thresholds could be found in the left ear at 125 and 250 Hz, and in both ears at 500 and 2000 Hz （ P 〈 0.05 ）. Conclusions Rapid changes in air pressure during fast buoyancy ascent escape had certain effects on the hearing of the submariners, with the decrease in hearing thresholds at low frequencies being the main effect.
