The middle ear consists of a chain of three bones (malleus, incus, and stapes) that are suspended by ligaments in an air-filled cavity in the head and are acted upon by two muscles, the stapedius and tensor tympani. The eardrum separates the middle ear from the ear canal and is connected to the malleus. Our understanding of the middle ear’s biomechanics has been enhanced by computer models. However, current models cannot be used to simulate high intensity sounds and reflexive contraction of the stapedius muscle. Extension of computer models is important for the engineering and design of diagnostic, assistive and protective devices.

中耳由三块骨头（锤骨、镫骨和镫骨）组成，它们由韧带悬挂在头部充满空气的腔中，并受镫骨和鼓室张肌这两块肌肉的作用。鼓膜将中耳与耳道分开，并与锤骨相连。计算机模型增强了我们对中耳生物力学的理解。然而，目前的模型不能用于模拟高强度的声音和镫骨肌的反射性收缩。计算机模型的扩展对于诊断、辅助和保护装置的工程和设计是重要的。
