TLDR
The analysis accounts for the frequency dependency shown by the empirical data and reconciles the differences observed between the coupling as measured by tympanic membrane vibration and auditory nerve responses.
Sound, Speech, and Hearing
The basic physics of sound is first developed, including that of sound wave propagation in air and at interfaces, and of sound in resonant cavities, and these concepts are then applied to speaking
Biophysics, neural processing and robotics of the lizard ear, a highly directional sensor
The ear of lizards shows strongly directional responses with up to 40 dB differences in sensitivity to ipsiand contralateral stimulation. The directionality is generated by a simple principle: strong

TLDR
The implications of ICE in amphibians with respect to sound localizations are discussed, and the particularly interesting case of frogs that use ultrasound for communication yet exhibit exquisitely small localization jump errors is brought to light.

Sound Production in Birds: Acoustics and Physiology Revisited
In a volume concentrating on methods in the analysis of acoustic communication, two roles are served by a chapter on how one group of vocal virtuosos, namely birds, make sound. The first is to inform
Resonators in insect sound production: how insects produce loud pure-tone songs.
TLDR
Although in many insects the song may appear to be produced by the excitation of a simple resonator, the song frequency may not be constant, suggesting that other factors, such as the mechanism of excitation, or variation of the effective mass or elasticity of the system during sound production, may be additional determinants of thesong frequency.
Acoustic Systems in Biology: From Insects to Elephants
TLDR
This lecture will explore all these matters and perhaps some more of the mechanisms of sound production and directional hearing used by animals for communication, for seeking prey, and for avoiding predators.
Directional hearing by mechanical coupling in the parasitoid fly Ormia ochracea
TLDR
The data point to a novel mechanism for directional hearing in O. ochracea based on intertympanal mechanical coupling, a process that amplifies small acoustic cues into interaural time and amplitude differences that can be reliably processed at the neural level.
Auditory Information Processing in Systems with Internally Coupled Ears
Several animals, in particular, lizards, possess a specialized hearing mechanism: internally coupled ears (ICE), where the tympanic membranes are coupled through a large mouth cavity. An analytically
