Perceptual grouping decides whether acoustic events fuse into one or split into several sounds

Evidence

Auditory perception is associated with a number of computational processes, which may act in parallel or serial, including: perceptual grouping, decision-making, attention, and categorization. (1) Perceptual grouping is a form of feature-based stimulus segmentation that determines whether acoustic events will be grouped into a single sound or be segregated into distinct sounds (Bregman 1990 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 4881
