Sound events arranged in time and frequency are perceptually organized into streams.

Evidence

As an example of the perceptual organization of auditory events, we will inspect the formation of a melodic line, which is an important structural factor in Western musical tradition. If we listen to sound events placed properly both in time and frequency, depending on the case, we will perceive one or more auditory streams (Bregman, 1990; McAdams and Bregman, 1979). A broader term for the perceptual organization of sound is auditory scene analysis (Bregman, 1990). — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1334
