Otoacoustic Emission through Waves on Reissner's Membrane
Basilar membrane vibration is not involved in the reverse propagation of otoacoustic emissions
The current data indicate that basilar membrane vibration was not involved in the backward propagation of otoacoustic emissions and that sounds exit the cochlea probably through alternative media, such as cochlear fluids.
Hydromechanical Structure of the Cochlea Supports the Backward Traveling Wave in the Cochlea In Vivo
This study showed the backward traveling wave by measuring the phase spectra of the basilar membrane vibration at multiple longitudinal locations of the basal turn of the cochlea and a transmission line mathematical model was used to interpret why no tonotopicity was observed in the backward traveled wave.
A wave of cochlear bone deformation can underlie bone conduction and otoacoustic emissions
A sound signal is transmitted to the cochlea through vibration of the middle ear that induces a pressure difference across the cochlea’s elastic basilar membrane. In an alternative pathway for
A cochlear-bone wave can yield a hearing sensation as well as otoacoustic emission
A novel propagation mode within the cochlea that emerges through deformation of the coChlear bone is described and it is demonstrated that this propagation mode can explain bone conduction as well as numerous properties of otoacoustic emissions.
The physics of hearing: fluid mechanics and the active process of the inner ear.
The two forms of motility constitute an active process that amplifies mechanical inputs, sharpens frequency discrimination, and confers a compressive nonlinearity on responsiveness: the cochlea and the bifurcation.

We investigated the dispersion relations of the triple-chambered cochlea separated by the basilar membrane and the Reissner's membrane. The slow waves can propagate on the basilar membrane (basilar
Modelling cochlear micromechanics
The present work studies the behaviour of a radial slice of the cochlea at the microscopic level using finite element method and calculates the individual motion of each component within the organ of Corti with static pressure loading on the BM.
Two-compartment passive frequency domain cochlea model allowing independent fluid coupling to the tectorial and basilar membranes.
A two-dimensional two-compartment finite difference model of the cochlea was developed to investigate the independent coupling of the basilar and tectorial membranes to the surrounding liquid.
Auditory distortions: origins and functions.
Examination methods based on the detection of distortions open noninvasive windows on the modes of activity of mechanosensitive structures in auditory sensory cells and on the distribution of sites of nonlinearity along the cochlear tonotopic axis, helpful for deciphering co chlear molecular physiology in hearing-impaired animal models.


Reverse wave propagation in the cochlea
It is shown that BM vibration amplitude and phase at the cubic distortion product (DP) frequency are very similar to responses evoked by external tones, consistent with the idea that the emission comes out of the cochlea predominantly through compressional waves in the co chlear fluids.

The results show that, in cases in which it can be expected, the DP emission is delayed relative to the DP in a way that supports reverse-traveling-wave theory, and show spatial variation in DPs that is at odds with a compression pressure.
Reverse cochlear propagation in the intact cochlea of the gerbil: evidence for slow traveling waves.
The group delay between intracochlear emission-generation and their recording in the ear canal was determined, and the results contradict the hypothesis that the reverse propagation of emissions is exclusively by direct pressure waves.
Fast reverse propagation of sound in the living cochlea.
Energy flow in the cochlea
With moderate acoustic stimuli, measurements of basilar-membrane vibration (especially, those using a Mössbauer source attached to the membrane) demonstrate: a high degree of asymmetry, in that the
Wave propagation in the cochlea (inner ear): Effects of Reissner's membrane and non-rectangular cross-section
SummaryThe wave propagation in the inner ear (cochlea) is simulated with consideration of the complicated structure. The cochlea represents a system consisting of three parallel, fluidfilled tubes,
Otoacoustic Emissions from Residual Oscillations of the Cochlear Basilar Membrane in a Human Ear Model
Simulation results and theoretical considerations based on a hydrodynamic model of the human inner ear show that this approach can be exploited to provide novel diagnostic tools and a better understanding of key phenomena relevant for hearing science.

Data obtained at different frequencies show the relationship between the longitudinal pattern and frequency tuning, demonstrating that the observed localized traveling wave in this study is indeed the spatial representation of the sharp tuning observed in the frequency domain.
The origin of periodicity in the spectrum of evoked otoacoustic emissions.
Ear-canal measurements are related to cochlear mechanics by assuming that the transfer characteristics of the middle ear vary slowly with frequency compared to oscillations in the emission spectrum, and Measurements of basilar-membrane motion in the squirrel monkey are used to predict the spectral characteristics of their emissions.
Mechanics of the mammalian cochlea.
In mammals, environmental sounds stimulate the auditory receptor, the cochlea, via vibrations of the stapes, the innermost of the middle ear ossicles. These vibrations produce displacement waves that
