How do blind people see sound?

Blind people "see" sound primarily through echolocation, a skill where they emit sounds (like tongue clicks or cane taps) and interpret the returning echoes to build a mental map of their surroundings, perceiving objects' size, shape, distance, and texture, much like bats or dolphins. This involves specialized auditory processing, where the brain, especially the visual cortex, activates to process these sound cues, creating a rich spatial awareness to navigate independently.
