The frequency specificity of the auditory brainstem response (ABR) was examined by means of pure‐tone masking profiles using click, 4000‐Hz, and 1000‐Hz filtered‐click stimuli. Simultaneous pure‐tone maskers were presented at one‐half octave intervals around stimulus center frequency. Masking profiles at two intensities (60 and 40 dB SL) were obtained by measuring both latency and amplitude shifts in wave V as a result of the discrete‐frequency maskers. Both latency and amplitude analyses showed masking profiles at 40 dB SL that were narrow and centered around stimulus frequency, whereas profiles at 60 dB SL showed high‐frequency spread of the cochlear excitation area.
