The Blind Individuals Who See by Sound

How the human brain adapts to blindness and allows us to see our world
through echolocation.

Daniel Kish has been blind since he was 13 months old, but you wouldn’t be
able to tell. He navigates crowded streets on his bike, camps out in the
wilderness, swims, dances and does other activities many would think
impossible for a blind person. How does he do it? Kish is a human
echolocator, a real life Daredevil. Using a technique similar to what bats
and dolphins use, human echo-locators navigate using audio cues given off by
reflective surfaces in the environment.
