Auditory brainstem response (ABR) waveforms recorded from a tympanic-membrane electrode, without (red) and with (gray) the contralateral acoustic stimulus (CAS). All ABR peaks are deflected downward. The cochlear-nerve compound action potential (CAP) is the first negative deflection. Each waveform is the result of approximately 10 hours of response averaging. CAS with broadband noise reduced CAP amplitudes in all subjects.
