[Characteristic for lateralization of bitonal complexes]

In two subjects, bitonal complex with odd frequencies had the significance of lateralization threshold lesser by half of the single-tone signal threshold according to interaural time difference. In bitonal complex with even frequencies the threshold was still less which indicates a greater interaction of tones with even frequencies. Greater thresholds of lateralization were observed in bitonal complexes by interaural difference in intensities of the higher tone of the complex as compared with the same threshold for single-tone signal. Curves of the dependence of lateralization threshold of bitonal complex by interaural difference in intensities of the higher tone of the complex upon the interaural time differences of: 1) bitonal signal, 2) low-pitched tone, 3) high-pitched tone, were obtained.
