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 ...

Reverberation localization (echolocation) is a method of knowing the distance, direction, size, etc. of an object from the echo of the emitted sound or ultrasonic waves, and is known to be performed ...

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 ...

Blind humans have been known to use echolocation to "see" their environment, but even sighted people can learn the skill, a new study finds. Study participants learned to echolocate, or glean ...

There's a vast world around us that animals can perceive — but humans can't. Pulitzer Prize-winning science writer Ed Yong uses the example of a dark room: Though it might seem that there would be ...

What do bats, dolphins, and submarines have in common? They use the same technique to get a sense of their surroundings: echolocation. Here, an animal or a device emits sound waves, and listens for ...

Nature’s own sonar system, echolocation occurs when an animal emits a sound wave that bounces off an object, returning an echo that provides information about the object’s distance and size. Over a ...
