In order to investigate the mechanisms of bone conduction, a finite element model of the human head was developed. The most important steps of the modelling process are described. The model was excited by means of percutaneously applied forces in order to get a deeper insight into the way the parts of the peripheral hearing organ and the surrounding tissue vibrate. The analysis is done based on the division of the bone conduction mechanisms into components. The frequency-dependent patterns of vibration of the components are analyzed. Furthermore, the model allows for the calculation of the contribution of each component to the overall bone-conducted sound. The components interact in a complicated way, which strongly depends on the nature of the excitation and the spatial region to which it is applied.
为了研究骨传导机制,建立了一个人头的有限元模型。描述了建模过程中最重要的步骤。通过经皮施加力来激励该模型,以便更深入地了解外周听觉器官各部分和周围组织的振动方式。基于将骨传导机制划分为各个组成部分来进行分析。分析了各组成部分与频率相关的振动模式。此外,该模型能够计算每个组成部分对整体骨导声音的贡献。各组成部分以复杂的方式相互作用,这在很大程度上取决于激励的性质及其所施加的空间区域。
