Lateralization of brief clicks was studied while the frequency content of the clicks was altered by filtering. The subject was asked to discriminate a centered image, a pair of identical clicks that arrived simultaneously at the two headphones, from a displaced image, a pair of identical clicks in which the click to the left ear was slightly delayed. The discrimination of the lateral position deteriorated as the clicks were high‐pass filtered beyond 1500 Hz and was largely unaffected by low‐pass filtering. Masking with high‐pass and low‐pass noise showed that low‐pass noise severely disrupted the lateralization of the high‐pass clicks, but the high‐pass noise produced no disruption of the lateralization of the low‐pass clicks. Our results suggest that the discrimination of lateral position depends largely on the low‐frequency content of the click and thus, presumably, on the apical end of cochlear partition.
