提出了一种猫鼓膜的有限元模型，该模型考虑了鼓膜的三维弯曲圆锥形状的影响。该模型在低频（低于1-2 kHz）和线性振幅范围内是有效的。材料性能基于文献综述。关键的材料参数是刚度（2 × 100）。108达因cm-2）和张力部的厚度（40 μ m）。该模型表现出的振动模式和振幅非常相似的实验观察到的激光全息。改变了一些参数，以研究它们在模型中的相对重要性。
A finite-element of the cat eardrum was presented which included the effects of the 3-dimensional curved conical shape of the drum. The model was valid at low frequencies (below 1-2 kHz) and within the range of linear vibration amplitudes. The material properties were based on a review of the literature. The critical material parameters were the stiffness (2 .times. 108 dyn cm-2) and thickness (40 .mu.m) of the pars tensa. The model exhibited a vibration pattern and amplitude very similar to those observed experimentally using laser holography. A number of parameters were varied to study their relative importance in the model.
