Lateralization of partials of complex tones with pure tones

The ability to detect lateralization images of individual partials of harmonic tone complexes with pure tones was measured in a yes/no task. It is supposed that partials of complex tones build up lateralization images with pure tones of equal frequency and amplitude. It has been found that the upper limit of lateralization produced by introducing interaural time differences is slightly reduced from that in pure‐tone‐pure‐tone cases. No difference in correlation has been found between lateralization obtained with partials resolved or unresolved by the ear or with those partials covering the “dominance region.” The results are in good agreement with data reporting of fusion at higher frequencies between dichotically presented signals with gross interaural frequency differences.
