老鼠在听觉研究中可能非常有用，因为中耳结构很容易接近，而且老鼠相对便宜。本研究的目的是通过测量鼓膜和鼓膜上多个点的频率响应来更好地表征大鼠中耳的力学特性。使用激光多普勒振动计测量振动。对7只大鼠进行了测量。鼓膜振动呈现为1-10 kHz频率范围内的7个不同点。测量的重复性和动物间的变异性在脐也提出。研究了鼓膜和手的振动模式。版权所有（C）2007 S. Karger AG，巴塞尔。
Rats are potentially very useful for auditory research because the middle ear structures are easily approachable and because rats are relatively inexpensive. The goal of the present study was to better characterize the mechanics of the rat middle ear by measuring frequency responses at multiple points on the tympanic membrane and manubrium. A laser Doppler vibrometer was used to measure the vibrations. Measurements were made on 7 rats. Tympanic membrane vibrations are presented for 7 different points in the frequency range of 1-10 kHz. The repeatability of the measurements and the interanimal variability at the umbo are also presented. The vibration modes of the tympanic membrane and manubrium were investigated.
