Definition

The ability to localize sounds in space, and the way in which such a task is performed, is not fixed. If the physical cues for sound localization are altered, ability is initially disrupted. However, following experience with the new set of cues, a degree of the original performance is regained, accompanied by various changes in auditory processing.

Detailed Description

Localizing sound sources in the external world requires the integration of multiple cues. The relative time of arrival and sound level across the two ears depend on which side of the head the sound originates from (azimuth) and frequency-dependent filtering by the head and ears that depends on the vertical angle of the sound source (elevation). For a given location these cues correspond, but not uniquely for a given frequency. Thus, information is integrated across different monaural and binaural cues and different frequency ranges. The correspondence of cue values also depends on individual’s head and outer...
