Cochlear Microphonic Potentials

Cochlear microphonic potentials, recorded with round window electrodes, were obtained from six patients in the operating room. The response criterion consisted of the sound pressure level, for which the cochlear voltage was at a minimum reading at each of five test frequencies. These data were compared to standard audiometric thresholds for the same ears. The relationships between audiometric (behavioral) data and electrophysiological responses indicate comparable frequency sensitivity to sound. Cochlear microphonic measurement presents a valid method for approaching the threshold of auditory sensitivity in man.
