When the ear is stimulated by two tones presented at frequencies f1 and f2, nonlinearity in cochlea's vibratory response leads to generation of distortion products (DPs), with cubic 2f1-f2 DP commonly viewed as most prominent. While quadratic f2-f1 also evident numerous physiological perceptual studies, its presence mechanical has been less well documented. Here, examination DPs within mouse cochlea confirmed that was a significant sometimes dominant component, whether were measured near their site, or after having propagated from more basal locations.
