Most of us associate echolocation with bats. These amazing creatures are able to chirp at frequencies beyond the limit of our hearing, and they use the reflected sound to map the world around them. It ...

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 ...

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 ...

The call that comes back as a map A bat leaving its roost at dusk emits ultrasound pulses at frequencies between 20 and 200 kilohertz, well above the ceiling of human hearing, which tops out around 20 ...

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 ...

Neuroscientists at Goethe University, Frankfurt have discovered a feedback loop that modulates the receptivity of the auditory cortex to incoming acoustic signals when bats emit echolocation calls. 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 ...

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.

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 ...
