    • A finite element model of an ear stored on a computer readable medium having logic representing a three-dimensional geometric model of the ear; logic for meshing individual anatomical structures of the ear accounting for whether the anatomical structures include at least one of air, liquid material and solid material; logic for assigning material properties for each anatomical structure based on at least one physical property of each anatomical structure; logic for assigning boundary conditions for some of the anatomical structures indicative of interaction between such anatomical structures; and logic for employing acoustic-structural coupled analysis to the anatomical structures of the ear to generate data indicative of the acoustic effect on mechanical vibration transmission in the ear. Various embodiments of "one-chamber" and "two-chamber" analyses and models are described.
    • 存储在具有表示耳朵的三维几何模型的逻辑的计算机可读介质上的耳朵的有限元模型; 用于啮合耳朵的个体解剖结构的逻辑,以解释解剖结构是否包括空气,液体材料和固体材料中的至少一种; 基于每个解剖结构的至少一个物理属性为每个解剖结构分配材料属性的逻辑; 用于为指示这种解剖结构之间的相互作用的一些解剖结构分配边界条件的逻辑; 以及用于对耳朵的解剖结构采用声学结构耦合分析以产生指示在耳朵中的机械振动传播的声学效应的数据的逻辑。 描述了“单室”和“两室”分析和模型的各种实施例。
