Ben Underwood Human with a Sonar Vision - Ben Underwood is a blind American teen who uses echolocation to move around avoiding obstacles.

Ben Underwood is blind, his eyes had been damaged by cancer, when she was 3 years old. However, he plays basketball, rides on a bicycle, and lives a quite normal. He trained himself to use sonar waves to navigate around the world, without a guide dog to lead him, without a hand to touch-touch, he uses SOUND!

Ben produces sound then bounces on an object and echoes it back to him. He was one-the only person in the world who look at using sonar sound like dolphins-dolphins, sea vessels, and bats.

Human echolocation is an ability of humans to detect objects in their environment by sensing echoes from those objects. By actively creating sounds-for example, by tapping their canes, lightly stomping their foot or making clicking noises with their mouths-people trained to orientate with echolocation can interpret the sound waves reflected by nearby objects, accurately identifying their location and size. This ability is used by some blind people for acoustic way finding, or navigating within their environment using auditory rather than visual cues. It is similar in principle to active sonar and to the animal echolocation employed by some animals, including bats, dolphins and toothed whales Advertisement
