激光多普勒振动法是测量鼓膜振动的一种有效方法。客观诊断中耳是合适的。激光多普勒测振法比鼓室法具有更高的灵敏度。特别制备颞骨标本，模拟中耳积液、踝头固定、镫骨底板固定、砧骨取出等中耳疾患。一个相关的位移函数之间的umbo和实验中产生的中耳疾病可以证明。利用激光多普勒测振仪测量25岁健康男性鼓膜振动首次成为可能。
Laser-Doppler-vibrometry is a useful method to measure vibrations of the tympanic membrane. It is suitable to objectively diagnose the middle ear. In comparison to tympanometry, laser-Doppler-vibrometry has greater sensitivity. Temporal bone specimens were specially prepared to simulate middle ear disorders like middle ear effusion, fixation of the malleus head, fixation of the stapes footplate and removal of the incus. A correlation between the displacement function of the umbo and the experimentally produced middle ear disorders could be demonstrated. For the first time it was possible to measure the vibration of the tympanic membrane by using a laser-Doppler-vibrometer in a healthy 25-year-old male.
