Justin Louchart is one of the few men who is 100% blind, but still manages to see. Using his mouth to make sounds that reflect off nearby objects, Louchart demonstrates the superhuman skill of echolocation. He can map the shapes, distance and texture of objects just by making sounds and receiving echoes. Louchart is so adept at his skill that he claims he would not trade his sight through sound for sight through vision. After host Tyler Harcott learns about how sound moves and behaves with professor and sound engineer Jeff Merkel, he challenges Louchart to demonstrate his abilities in a real world test. Can Louchart navigate his way through a dense forest with only echolocation? How much can Louchart truly see?
