Ben Underwood was blind, but while he was alive, he got around almost as well as people who can see, and even played video games with his friends. That’s because he had done something that’s very unusual: Ben Underwood taught himself how to echolocate. Underwood trained his ears to listen for the echoes that tongue-clicking sounds that he produced made as they bounced back off of objects. He then processed that information to figure out where physical objects lie around him.
