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.
I used to deer hunt with my father, and his tree stand was insanely high at over 70ft (he liked to think of himself as a sniper) and you could definitely hear the difference when you were the high in the trees than if you were in my stand which was at a much less terrifying 20ft off the ground.
To be fair that isn't hunting.
