Abstract :
Many insects are endowed with small, yet very powerful hearing organs whose signal processing characteristics are very similar to those of the mammalian cochlea. We investigate self-sustained oscillation (SO) data of the Drosophila hearing organ and demonstrate that they are faithfully described by a generalized van-der-Pol system. Technical applications may benefit from a profound understanding of this compact and sensitive sound detector.
