Microphonic potentials were recorded from guinea pig cochleas with differential electrodes placed into the first and third turns. Distortion components of (n+1)flânfh (particularly 2flâfh) and fhä±fl were studied as a function of frequency separation between the primaries and as the function of primary intensities. The conclusion is drawn that all distortion components in the cochlear microphonic behave alike, that is, there is no fundamental distinction between the properties of 2flâfh and fhâfl. Some properties of the interference phenomenon are also examined in this study. It is suggested on the basis of the present results on distortion in cochlear microphonics and those in the literature treating subjective measures of distortion, that the role of microphonic potentials in the peripheral transduction process should be re examined.
