Abstract

In our former studies, it was found that even if there was relatively long overlapping between two successive sounds with long decay, the overlapping wasn't detected. We related this phenomenon to self-masking, that is, masking of the former portion of a sound to the latter portion of the same sound. At the same time, this phenomenon might be caused by cognitive factor like whether two sounds are grasped as single sound event. In this study, the localization of each sound was controlled by varying interaural level difference of each sound and it was investigated whether this phenomenon was caused by perceptual factor like self- masking or cognitive factor like cognition of sound event.
