摘要

蝙蝠的生物声纳系统利用超声波接收部位周围的物理挡板形状进行基于衍射的振幅调制。据推测，蝙蝠抗蛙会影响蝙蝠的生物进化。利用数值方法，我们证明了中国鲎的对耳部具有增加近场声学和提高外耳反射系数的作用。模拟结果提供了生物信号器信号与形态结构之间的直接联系。该效应的性质表明，潜在的物理机制是在耳廓和对舌之间产生驻波。

Antitragus Suppresses Fundamental Harmonic Pulse in a Horseshoe Bat, Rhinolophus Sinicus

The biosonar system of bats utilizes physical baffle shapes around the sites of ultrasound reception for diffraction-based amplitude modulation. Bat antitragus has been hypothesized to affect the bat biosonar. Using numerical methods, we show that the antitragus of a Chinese horseshoe bat has an effect on increasing the acoustic near field as well as enhancing the reflection coefficient of the external ear. The simulation result provides a direct link between the biosonar signal and the morphological structure. The underlying physical mechanism suggested by the properties of the effect is that standing waves are produced between the pinna and antitragus.
