Abstract
Auditory brainstem responses evoked by both clicks and 0.5 kHz tone-bursts were recorded using the derived-band parad gm in 10 normal-hearing subjects. The derived-band analyses showed a similar distribution of activity with both stimuli, the largest contributions coming from the 2–4 and 4–8 kHz bands. Neither the click nor the 0.5 kHz tone-hurst is a frequency-specific stimulus, and both woulc appear to be unsuitable for brainstem response audiometric evaluation of the apical cochlea.
