Study Shows How Humans Can Echolocate
sciencehabit writes: Blind from infancy, Daniel Kish learned as a young boy to judge his height while climbing trees by making rapid clicking noises and listening for their echoes off the ground. No one taught him the technique, which is now recognized as a human form of echolocation. Like Kish, a handful of blind echolocators worldwide have taught themselves to use clicks and echoes to navigate their surroundings with impressive ease — Kish can even ride his bike down the street. A study of sighted people newly trained to echolocate now suggests that the secret to Kish's skill isn't just supersensitive ears. Instead, the entire body, neck, and head are key to 'seeing' with sound — an insight that could assist blind people learning the skill.
Really what Stardner is describing is called "hearing"
Or even more accurately "hearing with both ears" because the stereo sound field is processed by the brainworks computrons to sense direction of sounds etc
If you'e seen videos of him doing the supposed "riding bike down the street," he only gets a handful of meters, slowly, and it is a very painstaking bike ride. They even edit his video to show the more successful parts. I looked into this after seeing his TED talk -- while echolocation seemed pretty neat, it definitely seems like his foundation is exaggerating its efficacy. It definitely does something, his bike riding is awkward at best but I think it's talked up in an effort to encourage others to learn it as well.
