基于耳道和前庭阶压力的比较，沙鼠中耳以约25 dB的增益传输声音，该增益在2至40 kHz之间几乎是平坦的，并且具有对应于25 - 30 μs延迟的延迟样相位。中耳如何能够以如此高的时间和振幅保真度传输声音尚不清楚，并且鉴于已知听小骨和鼓膜（TM）经历的复杂运动，中耳如何能够以如此高的时间和振幅保真度传输声音尤其神秘。为了探讨这个问题，我们观察了运动员的速度，并沿着TM上的一条线沿着观察。TM运动是复杂的，并且可以近似为波浪状运动和进出活塞状运动的组合。在某些频率的刺激下，手关节会发生弯曲，因此它的运动不像刚体。它有一个复杂的运动与频率精细结构，似乎很可能是来自共振的鼓状TM。
Based on comparisons of ear canal and scala vestibuli pressures the gerbil middle ear transmits sound with a gain of ~25 dB that is almost flat from 2 to 40 kHz, and with a delay-like phase corresponding to a 25 – 30 μs delay. How the middle ear is able to transmit sound with such high temporal and amplitude fidelity is not known, and is particularly mysterious given the complex motion the ossicles and tympanic membrane (TM) are known to undergo. To explore this question, we looked at the velocities of the manubrium and along a line on the TM. The TM motion was complex, and could be approximated as the combination of a wave-like motion and an in-and-out piston-like motion. The manubrium underwent bending at some stimulus frequencies and therefore its motion was not like a rigid body. It had a complex motion with frequency fine structure that seemed likely to be derived from resonances on the drum-like TM.
