Audio Beacon

A spatial audio cue, typically a repeating tone or beep, attached to a specific location or object to help users with visual impairments navigate toward or identify points of interest in physical or virtual environments. Audio beacons vary in parameters such as pitch, timbre, volume, and frequency to convey distance and direction information. They are widely used in accessible navigation systems, virtual reality environments, and assistive technology applications like Microsoft Soundscape, providing a simple but effective way to convey the presence and location of objects or destinations without visual information.
