... extending from 125 Hz to 4 kHz (5 octaves) with most-sensitive hearing between 0.8 kHz and 1.4 kHz. The high-frequency cut-offs are the lowest found in mammals to date. In contrast to predictions from middle ear morphology, F. mechowii did not show higher sensitivity than F. anselli in the low-frequency...

... be enhanced via the acoustic coupling of middle ear cavities, resulting in a pressure difference receiver (PDR) mechanism. The experiments reported here support a role for a PDR mechanism in alligator sound localization by demonstrating that (1) acoustic space cues generated by the external morphology...

.... This is corroborated by experimentally artificially loading the TM. The product of area ratio and footplate vibration amplitude would result in similar stimulation of the inner ear in the two sexes.

...Yehudah L. Werner; Petar G. Igić; Merav Seifan; James C. Saunders SUMMARY Previous studies of electrophysiological audiograms in gekkonomorph lizards revealed greater sensitivity in adults than in juveniles. We investigated whether this difference, as far as it is affected by the middle ear...

... ; Mason and Narins,2002 ), which identify what is here termed the footplate axis as the point of rotation (see Fig. 1 ). The anatomy of the middle ear apparatus of frogs suggests that the stapes rocks about this axis in an approximately vertical plane( Bolt and Lombard, 1985 ). Ossicular movement...
