An open microflow meter system has been worked out for quantitative recording of the volume displacement of the tympanic membrane and its movement direction at stapedius reflex. An acoustically elicited M. stapedius contraction can be recognized by the characteristic response and latency time. The stapedius reflex contraction causes an outward or inward movement of the tympanic membrane. The magnitude of the volume displacement of the tympanic membrane is influenced by the middle ear pressure and in some ears the movement direction of the tympanic membrane changes.
已设计出一种开放式微流量计系统，用于定量记录镫骨肌反射时鼓膜的体积位移及其运动方向。通过特征性反应和潜伏期，可以识别出由声音诱发的镫骨肌收缩。镫骨肌反射收缩会导致鼓膜向外或向内运动。鼓膜体积位移的大小受中耳压力影响，在某些耳朵中，鼓膜的运动方向也会发生变化。
