Human Echolocation

Human echolocation is a skill where some visually impaired individuals produce sounds—like clicking their tongues or tapping a cane—and listen to the echoes that bounce off objects nearby. These echoes provide information about the environment, helping them identify the location, size, shape, and distance of objects. The brain processes these auditory cues, allowing a person to "see" their surroundings through sound. This remarkable ability demonstrates how humans can adapt and utilize sensory information in versatile ways, effectively turning sound into a form of spatial awareness.
