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 ...

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 ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Bats are well known for their ability to “see” with sound, using ...

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 ...

Echolocation isn’t just for bats and dolphins—people can do it, too. Some blind people have learned to use echolocation to tell the size, density, and texture of objects around them, and researchers ...

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 ...

Toothed whales use sound to find their way around, detect objects, and catch fish. They can investigate their environment by making clicking sounds, and then decoding the "echoic return signal" ...

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 ...

Human echolocation refers to the remarkable ability of some individuals to utilise self-generated sounds – typically mouth clicks – and interpret the returning echoes to derive detailed spatial ...

We all know the routine with super powers: a mutated gene, alien origin, or a magic object are required, and usually some cataclysmic family event for motivation. Matt Murdock, better known as ...

Would you consent to a surveillance system that watches without video and listens without sound? To study author Dr. Xinhua Guo at the Wuhan University of Technology, the system may be more palatable ...
