FIG. 9.
Time–domain cortical auditory evoked potential waveforms are shown. Each column shows individual normal-hearing subject’s data at different ripple densities (e.g., 0.25 ripples/octave). Stimuli were processed with the eight-channel noise vocoder simulation. The corresponding ripple density is displayed next to each waveform. Amplitude of “change” response decreases as ripple density increases.
