Abstract
In this paper, we clarify the role of variation in interaural level difference (ILD) and interaural time difference (ITD) due to head rotation in localization of spatially segregated sounds. Listeners were asked to distinguish between two sources of white noises having various ILDs/ITDs under head rotation. In ILD condition, the segregation rate reached 80% when the ILD between two sources at an angular difference of 36° corresponded to different sides, i.e., left and right hemisphere. However, the sound image was integrated into one when the sources corresponded to the same side. In ITD condition, two or three images were perceived regardless of the ITDs. This was because when only one source was used, it was perceived as separate lower- and higher-frequency images. In confirmations with low- and high-pass noises, the lower-frequency image was contained for lower than 1.2 kHz and the higher-frequency one was contained for higher than 1.7 kHz.
