    Development of hearing in the big brown bat

    We studied the development of hearing in newborn pups of the big brown bat, Eptesicus fuscus. In the majority of pups, the opening of both outer auditory canals occurred on or before postnatal day (PND) 7, but in...

    Mechanical basis of otoacoustic emissions in tympanal hearing organs

    Tympanal hearing organs of insects emit distortion–product otoacoustic emissions (DPOAEs), which in mammals are used as indicator for nonlinear cochlear amplification, and which are highly vulnerable to manipu...

    Otoacoustic emissions in bushcricket ears: general characteristics and the influence of the neuroactive insecticide pymetrozine

    The tympanal organ of the bushcricket Mecopoda elongata emits pronounced distortion-product otoacoustic emissions (DPOAEs). Their characteristics are comparable to those measured in other insects, such as locusts...

    Acoustic-induced motion of the bushcricket (Mecopoda elongata, Tettigoniidae) tympanum

    Bushcrickets have a tonotopically organised hearing organ, the so-called crista acustica, in the tibia of the forelegs. This organ responds to a frequency range of about 5–80 kHz and lies behind the anterior tymp...

    Otoacoustic emissions from insect ears: evidence of active hearing?

    Sensitive hearing organs often employ nonlinear mechanical sound processing which generates distortion-product otoacoustic emissions (DPOAE). Such emissions are also recordable from tympanal organs of insects....

    The generation of DPOAEs in the locust ear is contingent upon the sensory neurons

    Tympanal organs of insects emit distortion-product otoacoustic emissions (DPOAEs) that are indicative of nonlinear ear mechanics. Our study sought (1) to define constraints of DPOAE generation in the ear of Locus...
