Percentage of correct scores for left/right discrimination as a function of the pulse rate, averaged over the five subjects. The results for different interaural time difference (ITD) values are presented in separate graphs. The periodic condition without binaural jitter (k = 0) is depicted by the squares, the condition with small jitter (k = 0.125, 0.25, and 0.5) is depicted by the triangles, and the condition with large jitter (k = 0.75 and 0.9) is depicted by the circles. The error bars represent 95% confidence intervals.
