Lateralization of repeated filtered transients

The lateralization of a high-pass and a low-pass 40 dB SL, 0.1-msec transient was measured as a function of the number of repetitions of the transient and the repetition rate. A high-pass transient presented once required 100 /usec more interaural time for lateralization than did a low-pass transient presented once. Twelve repetitions of the high-pass transient yielded the same lateralization performance as that obtained with a low-pass transient. Repetition rate did not affect the lateralization of the high or low-pass transients, and number of repetitions did not affect the lateralization of the low-pass transients. These results were compared with results obtained with gated sinusoids presented with and without rise—decay times.
