I’m a bit skeptical about this story, but I’m not sure whether it’s just because it’s on AOL’s news service (not known for their cutting edge journalism) or whether it’s because it has a cutesy video of the boy ‘connecting’ with dolphins. If accurate though, it’s quite an amazing talent.
Completely blind since the age of 3, after retinal cancer claimed both his eyes (he now wears two prostheses), Ben has learned to perceive and locate objects by making a steady stream of sounds with his tongue, then listening for the echoes as they bounce off the surfaces around him. About as loud as the snapping of fingers, Ben’s clicks tell him what’s ahead: the echoes they produce can be soft (indicating metals), dense (wood) or sharp (glass). Judging by how loud or faint they are, Ben has learned to gauge distances.
