Prolongation of the Cochlear Microphonic in Man: Cochlear Microphonic Ringing

Abstract
During routine extra-tympanic electrocochleographic (ECochG) recording, in many cases more cycles are seen in the cochlear microphonic (CM) recording than are present in the acoustic stimulus. This phenomenon was termed CM ringing. Ringing is present in 69% of the normal subjects and in 43% of patients with deafness of different etiologies. In the cochlear and Meniere subgroups those cases showing ringing have a significantly larger CM amplitude (P < 0.001 and P < 0.01, respectively). The possible origin of this phenomenon is discussed.
