AbstractThe inclusion of structural elasticity amongst the resonant sections of the standard cochlear model is examined. An immediate implication of adding such mechanics is the production of realistic 2f1-f2 distortion product octoacoustic emissions (DPOAEs) with properties similar to those found in clinical recordings. Since the structural coupling is not dependent on any active mechanism, simulation provides an answer as to how dead ears produce cubic DPOAEs.
