Abstract
The goal of this study is to explore the effects of low barometric pressure on human hearing level in aviation environment. A hypobaric chamber was used to simulate low barometric pressure condition in aviation. 7 participants were exposed to the hypobaric chamber at 5 simulated altitudes (1500, 2400, 3000, 4000, and 5000 m). 5 frequencies pure tones (50, 100, 400, 1000, and 8000 Hz) were played at each altitude. The hearing thresholds were recorded. It was found that the hearing thresholds ascended with the increasing of simulated altitude under all the frequencies pure tones. There were significant differences of the hearing thresholds between altitudes mostly (P < 0.05). It could be concluded that low barometric pressure had negative effects on hearing threshold significantly. The hearing level decreased with the altitude raising. This study is useful for the pressure design, sound design, and audition protecting in low barometric pressure condition.
