Fig. 1.

Experimental stimuli. (a) Schematics of the stimulus presented to each ear. For clarity, only three of the four trapezoids are shown, and the fine structure characteristic is shown in one trapezoid only. The ramps slope down to the absolute threshold of each subject. Between the trapezoids, the amplitude was set to zero. (b) Schematics of the stationary portion of a periodic pulse train (Upper) and of a binaurally jittered pulse train (Lower). For clarity, in b, only the positive phase is shown even though the pulses are biphasic. Note that the binaural jitter preserves the interaural time difference (marked with arrows).
