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 ...

New research shows that the brains of sighted and blind people adapt in a similar way when they learn to use sound echoes to understand the world without vision. The study, led by Durham University, ...

Smart glasses that use a technique similar to a bat's echolocation could help blind and low-vision people navigate their surroundings, according to researchers. ustralian researchers have developed ...

Inspired by bats’ use of echolocation, researchers have developed smart glasses that transform visual information into unique sound representations that enhance the ability of blind and ...

A team of researchers at the University of Technology in Sydney, Australia have designed a new tool that could allow people who are blind or who have low vision or other vision impairments to “see,” ...

Bats are nocturnal hunters and use echolocation to orient themselves by emitting high-frequency ultrasonic sounds in rapid succession and evaluating the calls' reflections. Yet, they have retained a ...

Echolocation lets animals use sound as a guide in places where vision fails. They send out clicks, chirps, or taps and interpret the returning echoes to find prey, avoid danger, or move confidently in ...

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" ...
