Spontaneous changes in middle ear pressure were measured tympanometrically in 15 healthy adults over 7.5 h under basal conditions. Despite fluctuation of middle ear pressure no temporal pattern existed and there was no evidence of reciprocal changes in pressure between sides. When awake but at rest the middle ear pressure fluctuates around ambient pressure. Recordings of positive pressure may represent supportive evidence in favour of a net basal tendency to produce a positive middle ear pressure.
在基础条件下，对15名健康成年人进行了7.5小时的鼓室测量，以测量中耳压力的自发变化。尽管中耳压力存在波动，但不存在时间模式，且没有证据表明两侧压力存在相互变化。清醒但休息时，中耳压力在环境压力附近波动。正压记录可能代表支持产生正中耳压力的净基础倾向的证据。
