Cross‐frequency interactions in the precedence effect

The extent to which the precedence effect is observed when leading and lagging sounds occupy different spectral regions has been measured. Subjects, listening under headphones, were asked to match the lateral position of an acoustic pointer to that of a test stimulus composed of two binaural noise bursts with asynchronous onsets, parametrically varied frequency content, and different interaural delays. The precedence effect was measured by the degree to which the interaural delay of the matching pointer was independent of the interaural delay of the noise burst in the test stimulus. These results show an asymmetric frequency effect in which low frequencies dominate. For example, a stimulus composed of a high‐frequency (1.25 kHz) leading burst and a low‐frequency (0.45 kHz) lagging burst produces no precedence effect, whereas the reverse produces a strong precedence effect. These results are in qualitative agreement with those of Blauert and Divenyi [Acustica 66, 267–274 (1988)], despite numerous differenc...
