"I see," said the blind man

He knew my car was poorly parked because he produced a brief, sharp click with his tongue. The sound waves he created traveled at a speed of more than 1,000 feet per second, bounced off every object around him, and returned to his ears at the same rate, though vastly decreased in volume.
But not silent. Kish has trained himself to hear these slight echoes and to interpret their meaning. Standing on his front stoop, he could visualize, with an extraordinary degree of precision, the two pine trees on his front lawn, the curb at the edge of his street, and finally, a bit too far from that curb, my rental car. Kish has given a name to what he does -- he calls it "Flash Sonar" but it's more commonly known by its scientific term, echolocation. -- Men's Journal
