摘　　要：进行了舒适感问卷调查、纯音测听实验以及鼓膜上的力学分析.在问卷调查中,升压过程时的不舒适程度明显大于降压过程.在纯音测听实验中,低气压和常压下人的纯音测听结果未表现出明显差异,但气压波动时人的听力水平会暂时性大幅下降,清晰度也会降低.鼓膜的静力分析显示,鼓膜所受最大应力与大气升压速率成正比,最大应力部位主要集中在鼓脐部位.This paper makes a comfort questionnaire 9 pure tone audiometry test and mechanical analysis on the tympanic membrane. In the questionnaire survey, the degree of human discomfort under the increasing pressure condition is significantly higher than the decreasing pressure condition. In pure tone audiometry experiment, the test result shows that the listening ability has no obvious difference between low air pressure and normal pressure, but the ability and articulation of human hearing will temporarily decrease under environment of mutative atmospheric pressure. The static analysis of the membrane shows that the maximum stress of the membrane is proportional to the pressure of the atmosphere 5 and the maximum stress is mainly concentrated in the area of umbo.
