Document Summary

Rule of thumb used by a system. They are shortcuts: which can lead to auditory illusions. Its is a rule applied to organizing sensory inputs to determine: which elements of a scene belong to which object, which elements represent edges between an object and its background. Proximity sounds for s single source comes from one location. Similarity sounds from a single source tends to be similar pitch, loudness, timbre etc. Smoothness changes of location, pitch, loudness etc. in a smooth and continuous way. Proximity in time: sounds that occur in rapid succession usually from the same source. Good continuation: sounds that stay constant or change smoothly are usually from the same source. Demonstrates how heuristics compete with each other. Smoothness heuristic tries to groups by smoothly changing pitch: dominates at low speeds. Similarity heuristics tries to group by timbre: dominates a high speeds. Which can vary by: wavelength (inverse of frequency, intensity (number of photons, polarity.
