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 ...

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, ...

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 ...

[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 ...

Blind as a bat? Hardly. All bats can see to some degree, and certain species possess prominent eyes and a keen sense of vision. Take the Egyptian fruit bat (Rousettus aegyptiacus). This species is ...

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 ...

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 ...

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 ...

The fringe-lipped bat hunts by ear. The winged predator, found in South and Central America, eavesdrops on the male tungara frog’s mating call and decides on the moment to strike. When the time is ...

Scientists and roboticists have long looked at nature for inspiration to develop new features for machines. In this case, researchers from Ecole Polytechnique Fédérale de Lausanne (EPFL), Switzerland ...

People who are visually impaired will often use a cane to feel out their surroundings. With training and practice, people can learn to use the pitch, loudness and timbre of echoes from the cane or ...
