Distortion Product Otoacoustic Emission Component Behavior as a Function of Primary Frequency Ratio and Primary Level

Conclusions:

DPOAE components behave similarly but not identically as a function of f2/f1. The ear canal DPOAE is generally dominated by DPOAED. The behavior of DPOAED as a function of f2/f1 is entirely consistent with known properties of cochlear mechanics. The behavior of DPOAER is more variable across ears, perhaps reflective of the increased number of parameters that influence its final form. Attempting to use an f2/f1 that would allow a greater bias of the ear canal DPOAE toward one component or the other does not appear to be practical.
