To investigate the dynamic properties of human hearing, experiments in vivo and with cadaver specimens can be carried out. Furthermore, electrical or mechanical models can also be used to study specific phenomena and parameter sensitivities. Present electrical and mechanical models are often based on crude structural and kinematic simplifications in which testing is restricted to static loading or simplified investigations. To investigate both static and dynamic behavior of normal and pathological ears spatial mechanical models have to be established. The different parts of sound transmission--i.e., airborne sound, elastic membranes, fluids, and ossicles have to be represented by different mechanical systems. In this investigations, a rigid body model of the middle ear was investigated. For verification, simulation results with respect to static loads were compared with measurements reported previously by Hüttenbrink. In further investigations, the dynamic behavior of the model will be evaluated. Models for the tympanic membrane and inner ear will also be formulated in order to create a compositive model that describes the whole hearing process. By so doing the successful development of prostheses as well as diagnostic methods will be supported.
为了研究人类听觉的动态特性，可以进行体内实验和尸体标本实验。此外，电模型或机械模型也可用于研究特定现象和参数敏感性。目前的电模型和机械模型通常基于粗略的结构和运动学简化，其中测试仅限于静态加载或简化研究。为了研究正常耳朵和病理耳朵的静态和动态行为，必须建立空间力学模型。声音传播的不同部分，即空气传播的声音、弹性膜、流体和听小骨，必须由不同的力学系统来表示。在这项研究中，对中耳的刚体模型进行了研究。为了验证，将关于静态载荷的模拟结果与胡滕布林克先前报告的测量结果进行了比较。在进一步的研究中，将评估该模型的动态行为。还将建立鼓膜和内耳的模型，以创建一个描述整个听觉过程的综合模型。这样做将有助于成功开发假体以及诊断方法。
