Ear canal acoustic and round window electrical correlates of 2f1-f2 distortion generated in the cochlea.
Close parallels have been found between the behaviour of the distortion product 2f1-f2 measured acoustically in the meatus (ACDP) and the 2f1-f2 component (CMDP) measured in the gross cochlear electrical response from the round window during two-tone stimulation. The two response modes show comparable growth with increasing stimulus intensity. Their group latencies and their frequency-selective susceptibility to suppression by a third tone are very similar. The common origin of these two responses is discussed.
