Spectral analysis of cochlear bio potentials in evaluating the functional condition of the guinea pig inner ear

Spectral analysis of cochlear bio potentials in evaluating the functional condition of the guinea pig inner ear

Spectral estimates of bioelectric microphonic potentials and action potentials of the [guinea pig] cochlea were determined. Apparently, spectral characteristics of these potentials are different and enable a diagnostic classification to be made. A nonlinear dependence of the effective width of the energy spectrum on the acoustic signal intensity confirms the existence of the auditory feedback.
