1. serving to amplify sound.
cochlear microphonic any of the electrical potentials generated in the hair cells of the organ of Corti in response to acoustic stimulation.

coch·lear mic·ro·phonic

(kok'lē-ar mī-krō-fon'ik),
bioelectric potentials produced by the hair cells of the organ of Corti in response to sound that faithfully represent the frequency and intensity of the acoustic stimulation.

We then measured postdrug and postnoise compound action potentials and cochlear microphonic thresholds.
This electrophysiological procedure is composed of three auditory evoked potential parameters - Cochlear Microphonic (CM), Summating Potential (SP), and Action Potential (AP) [10,11].
The normal ECoG response is very complex, consisting of an AP, a summating potential (SP), and cochlear microphonic (CM) responses.
Auditory neuropathy spectrum disorder (ANSD) or auditory dys-synchrony is a condition where otoacoustic emissions (OAE) and/or cochlear microphonics are present, and auditory brainstem responses (ABR) and acoustic reflexes are absent or abnormal (1-4).
[7,8] They found that perfusion of air into the scala tympani resulted in a drastic decrease in the cochlear microphonics and in the amplitude of the compound action potential.
