FIG. 8.
Mean SACFs produced with the lag-window modification [Eq. (6); Fig. 5] for sine-phase stimuli with various f0's. For higher f0's (e.g., 200 Hz), the large SACF peak at l=5 ms contains large fine-structure side peaks, causing the nonmonotonic behavior of d′ observed in Fig. 6. For lower f0's (50 and 100 Hz), the SACF side peaks are small relative to the central SACF peak; nonmonotonic d′ behavior is not observed for these stimuli.
