Cochlear emissions simulated using one-dimensional model of cochlear hydrodynamics

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 results.
