    We have developed, and are continuing to refine, a detailed three-dimensional computational model based on an accurate cochlear geometry obtained from physical measurements. In the model, the . MODEL Physical Model This physical cochlear model is intended to represent the passive cochlear dynamics. No active elements are included in the structure. The 16 times scaled-up cochlear model has one duct. The cochlear File Size: 1MB.

    Index Terms—Auditory models, cochlear implants, simulating the passive cochlear hydromechanics en- It is a one-dimensional macromechan-ical model of the cochlea, in which .   An alternative is given for the approach of the two-dimensional problem presented in [12]. Because of the mathematical simplicity of this alternative, several extensions of the model are Cited by:

    The presented model is based on electro-mechanical analogy, with a simplified presumption of basilar membrane acting as a one-dimensional system of resonators. In the model, the entire length of cochlea is divided into electrically coupled sections with the resolution of eight sections per critical band (Bark). The hydromechanics . Mathematical models of cochlear mechanics are often used to test theories about cochlear function. One-dimen- sional (transmission line) models helped establish the travel- ing-wave character of basilar membrane motion (Zwislocki, ; Peterson and Bogert, ). Nonlinear models .

Stapes velocity was computed using a nonlinear, one-dimensional model of cochlear hydromechanics. The model's compliances and damping coefficients were mechanically nonlinear and instantaneously varying in proportion to simulated current injected into the cochlea.

Experimental data showing the spectral content of the pressure waveform near the eardrum during the delivery of sound and current to the cochlea were compared with model. Stapes velocity was computed using a nonlinear, one-dimensional model of cochlear hydromechanics.

This model. One general view is that OHC electromotility is a main component of the amplification process, and this has been supported by repeatable in vivo measurements. [1,19] This view has been widely incorporated in active cochlear models.

A basic difference between this and previous investigations is that here we treat an enclosed two-dimensional cavity as opposed to one-dimensional and open two-dimensional models Cited by: Abstract.
