The mechanical transmission of sound in the tympanal organ of adults and 5th instar larvae of Locusta migratoria and Schistocerca gregaria has been investigated by means of stroboscopic measurements within a frequency range from 1-20 kHz. Frequency dependent spatial distributions of amplitudes and phases of oscillation on the tympanal membrane and the Müller's organ could be demonstrated. Cuticular structures on the membrane may act as a lever arm (e.g. elevated process) and cause a transformation of the (unidimensional) membrane motion into components of displacements in the Müller's organ perpendicular, as well as even parallel, to the membrane. Sites of maximum relative displacements at distinct frequencies are found to be correlated to the course of the dendrites of the acoustic receptor cells. Differences in morphology of the tympanal organ between the two species as well as between adults and larvae always correspond to differences in the mechanical properties (resonances etc.). Consequently, differences or changes in the neurophysiological response characteristics of the different receptor cells have been found. Based upon these findings a correlation between the anatomical and physiological classification of the receptor cell groups is presented.
通过频闪测量，在1-20千赫的频率范围内，对成年飞蝗和沙漠蝗的鼓膜器官以及五龄幼虫的鼓膜器官中的声音机械传播进行了研究。可以证明鼓膜和米勒氏器官上振荡的幅度和相位的频率依赖性空间分布。膜上的表皮结构可能充当杠杆臂（例如隆起的突起），并导致（一维的）膜运动转化为米勒氏器官中垂直于甚至平行于膜的位移分量。发现在不同频率下最大相对位移的部位与听觉受体细胞树突的走向相关。两种物种之间以及成虫和幼虫之间鼓膜器官形态的差异总是与机械特性（共振等）的差异相对应。因此，发现了不同受体细胞的神经生理反应特征的差异或变化。基于这些发现，提出了受体细胞群的解剖学和生理学分类之间的相关性。
