The brain must decompose an unlabelled auditory mixture into coherent perceptual objects

Evidence

The fundamental problem in audition is determining the mechanisms required by the brain to transform an unlabelled mixture of auditory stimuli into coherent perceptual representations. This process is called auditory-scene analysis. The perceptual representations that result from auditory-scene analysis are formed through a complex interaction of perceptual grouping, attention, categorization and decision-making. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4876

• DEFINE: Names and defines auditory-scene analysis as the field’s core problem.
• XREF: Relates to my audio/soundscape reading — the ‘unlabelled mixture’ problem parallels the lo-fi soundscape/figure-ground discussions in The Soundscape.
