在人类和其他脊椎动物中，听觉通过毛细胞的主动收缩特性得到改善。类似的主动听觉机制现在在昆虫身上得到了证实。在蚊子身上，约翰斯顿的器官转换声音引起的触角鞭毛振动。非肌肉的“运动”活动增强了生理完整动物的鞭毛机械反应的灵敏度和调谐。该仪器能够自动驱动鞭毛，放大特定频率和强度的声音诱导振动。约翰斯顿的器官的电机相关的电活动强烈表明，蚊子的听力提高机械感受器运动。
In humans and other vertebrates, hearing is improved by active contractile properties of hair cells. Comparable active auditory mechanics is now demonstrated in insects. In mosquitoes, Johnston's organ transduces sound-induced vibrations of the antennal flagellum. A non-muscular 'motor' activity enhances the sensitivity and tuning of the flagellar mechanical response in physiologically intact animals. This meter is capable of driving the flagellum autonomously, amplifying sound-induced vibrations at specific frequencies and intensities. Motor-related electrical activity of Johnston's organ strongly suggests that mosquito hearing is improved by mechanoreceptor motility.
