Figure 11. Cumulative proportion of subjects who have frequency-specific responses (common component subtracted) with ≥0 dB signal-to-noise ratio (SNR) as a function of recording time.

Acquisition time was faster for male- (left) than female-narrated (right) multiband peaky speech with (A) four frequency bands presented diotically and (B) five frequency bands presented dichotically (total of 10 responses, five bands in each ear). SNR was calculated by comparing variance of signals high-pass filtered at 150 Hz across the auditory brainstem response interval of 0–15 ms to variance of noise in the pre-stimulus interval −480 to −20 ms.
