Abstract
The primary clinical utility of electrocochleography at the Louisiana State University Medical Center is the detection of hearing losses in children. This frequently requires the administration of a general anesthetic. Time required for this procedure could be shortened if stimuli were presented at a more rapid rate than the customary 10/s, provided the response amplitude is not significantly diminished by adaptation. The response amplitudes of 12 subjects were studied at stimulus rates of 10, 20, 40, and 80/s. An increase of response amplitude on the order of approximately 3:1 over the 10/s rate was found for the 80/s rate when the test interval for each was equal.
