Many reptiles, and other vertebrates, have internally coupled ears in which a patent anatomical connection allows pressure waves generated by the displacement of one tympanic membrane to propagate (internally) through the head and, ultimately, influence the displacement of the contralateral tympanic membrane. The pattern of tympanic displacement caused by this internal coupling can give rise to novel sensory cues. The auditory mechanics of reptiles exhibit more anatomical variation than in any other vertebrate group. This variation includes structural features such as diverticula and septa, as well as coverings of the tympanic membrane. Many of these anatomical features would likely influence the functional significance of the internal coupling between the tympanic membranes. Several of the anatomical components of the reptilian internally coupled ear are under active motor control, suggesting that in some reptiles the auditory system may be more dynamic than previously recognized.
许多爬行动物以及其他脊椎动物都有内部耦合的耳朵，其中存在明显的解剖学连接，使得一个鼓膜位移产生的压力波能够（在内部）通过头部传播，并最终影响对侧鼓膜的位移。这种内部耦合引起的鼓膜位移模式能够产生新的感官线索。爬行动物的听觉力学表现出比其他任何脊椎动物群体更多的解剖学变异。这种变异包括诸如憩室和隔膜等结构特征，以及鼓膜的覆盖物。许多这些解剖学特征可能会影响鼓膜之间内部耦合的功能意义。爬行动物内部耦合耳朵的几个解剖学组成部分受到主动运动控制，这表明在某些爬行动物中，听觉系统可能比以前认为的更具动态性。
