The vibrations of the ossicles were measured with a laser Doppler vibrometer in temporal bone specimens. The data contradicted the generally accepted view that the malleus and incus rotate about a fixed axis. The vibrations of the ossicles show a more complex pattern and, consequently, a more sophisticated model is needed to portray the behaviour of the middle ear in a satisfactory manner. But in turn models with many degrees of freedom make the identification process a very difficult task. This dilemma can be resolved if the system is divided into subsystems of less complexity where each subsystem can be studied in an appropriate manner. The excitation by electrostatic forces, as applied in this study, seems to be a powerful tool to make possible a study of parts of the ossicular chain.
使用激光多普勒振动计在颞骨标本中测量听小骨的振动。数据与普遍接受的观点相矛盾，即锤骨和砧骨绕固定轴旋转。听小骨的振动呈现出更复杂的模式，因此，需要一个更复杂的模型来令人满意地描绘中耳的行为。但反过来，具有许多自由度的模型使识别过程成为一项非常艰巨的任务。如果将系统划分为复杂度较低的子系统，其中每个子系统都可以以适当的方式进行研究，那么这个困境就可以得到解决。本研究中应用的静电力激发似乎是一种强大的工具，使对听骨链部分的研究成为可能。
