Which term describes perceiving the direction and distance of a sound?

Perceiving the direction and distance of a sound is called auditory localization. This skill relies on how the brain processes cues from both ears to determine where a sound is coming from and how far away it is. Two key binaural cues are interaural time differences (the slight difference in when a sound reaches each ear) and interaural level differences (the difference in loudness between ears). The shape of the outer ears and the head also helps the brain judge elevation and distance by giving spectral cues and by noting how distance changes the direct-to-reverberant sound ratio and high-frequency content. In orientation and mobility, learners practice interpreting these cues in real environments to stay oriented and move safely. Echolocation uses reflections off objects to infer the surroundings, which is related to spatial awareness but not the basic description of locating where a sound source is. Unilateral hearing loss can impair localization because it disrupts binaural cues, and the phases of adjustment to blindness pertain to psychosocial adaptation rather than auditory spatial perception.
