Many bat species emit echolocation calls and use the returning echoes to find their way, detect the presence of fluttering insects, and locate and catch them. A new study investigated this behavior in ...

[Kripthor] suspected that hunters were getting too near his house. When thinking of a way to quantify this belief he set out to build a triangulation system based on the sound of gunshots. The theory ...

Clicks, squeaks, chirps, and buzzes...though they may be difficult to distinguish to our ears, such sounds are used by echolocating animals to paint a vivid picture of their surroundings. By ...

For years, a small number of people who are blind have used echolocation, by making a clicking sound with their mouths and listening for the reflection of the sound to judge their surroundings. Now, ...

New research shows that blind and visually impaired people have the potential to use echolocation, similar to that used by bats and dolphins, to determine the location of an object. The study examined ...

Some blind people can use the returning echoes from clicking their tongues to "see" with echolocation, and now researchers have explored how this process builds up a picture of the outside world in ...

Bats and dolphins aren’t the only animals that can use echolocation to detect objects in their environments. Humans can use echolocation too, and it’s a game-changer for people who are blind. On ...

Human echolocation operates as a viable 'sense,' working in tandem with other senses to deliver information to people with visual impairment, according to new research. Ironically, the proof for the ...

Much like bats and dolphins, some people have developed the ability to analyze bouncing sound waves to generate a picture of their environment. Image via Flickr user poolski When a bat flies through ...

Ruben Graham-Morris, a blind eight-year-old boy, has mastered echolocation to get around on his own. Ruben was born with Leber's congenital amaurosis, a genetic disease that left him blind from birth.

Millions of years before humans invented sonar, bats and toothed whales had mastered the biological version of the same trick - echolocation. By timing the echoes of their calls, one group ...

This weekend, 3.6 million Americans took off their shoes. They emptied loose change out of their pockets. And, before they got on a flight to return from Thanksgiving, they stepped through an ...
