Possible Transform on the Basilar Membrane
The Journal of the Acoustical Society of America, 1971Cochlear models indicate that basilar membrane displacement in the basal region approximates a first-derivative transform of the input signal. Evidence regarding acoustic transients and their cochlear microphone equivalents in the guinea pig is cited to demonstrate this conversion and suggests the plausibility of the observations derived from models.

Basilar membrane motion in a spiral-shaped cochlea
The Journal of the Acoustical Society of America, 1978To examine the influence of the spiral coiling of the cochlear upon the motion of the basilar membrane, a mathematical model of the cochlea is constructed. The formulation of the problem leads to Laplace’s equation in three dimensions in a curvilinear coordinate system plus corresponding boundary conditons. By basing the choice of the coordinate system

Digital Simulation of Basilar-Membrane Motion
The Journal of the Acoustical Society of America, 1962In previous work, a computational model was derived for describing basilar-membrane displacement in the human ear. The model specifies membrane displacement at arbitrary points for known sound pressure at the eardrum. Its mathematical tractability makes it an attractive tool for digital analysis of speech and other auditory signals.

Delay estimation of disturbances on the basilar membrane [PDF]
IEEE Transactions on Acoustics, Speech, and Signal Processing, 1981 With current measurement techniques, it is impossible to directly observe the traveling wave on the basilar membrane over its entire length. Treating the mechanical propagation as a pure conduction delay, the travel time to a particular region can be inferred from the phase-frequency characteristics of the neural response.

Orthotropic material properties of the gerbil basilar membrane
The Journal of the Acoustical Society of America, 2007In this paper, two sets of experimental results to extract the two effective elastic moduli, the effective shear modulus, and the effective Poisson’s ratio for the gerbil cochlear partition are analyzed. In order to accomplish this, a geometrically nonlinear composite orthotropic plate model is employed.

The Localization of Pitch Perception on the Basilar Membrane
The Journal of General Psychology, 1935Resume Les potentiels electriques generes dans les cochlees des cochons d'Inde ont ete pris par des electrodes placees en contact avec la cochlee et les muscles du cou. Ces potentiels indiquent la capacite d'entendre de l'animal, parce qu'ils (1) sont absents chez les animaux sourds, (2) ils ont des seuils qui correspondent au seuil de l'ouie chez les ...

Modern Methods for Measurement of Basilar Membrane Displacements
Acta Oto-Laryngologica, 1977Basilar membrane displacements in response to sound at threshold intensities are in the fractional Angstrom range. Visual measurements, as used by Bekesy in his pioneering studies, are by definition limited to values above 10 000 A. The present paper discusses a number of modern techniques capable of taking measurements at lower Anstrom levels: One ...
