It uses the same high-frequency sound waves that bats use for echolocation, and that an OBGYN uses to image a fetus. At Delray, the ultrasound is turned into a weapon through a piece of headgear ...

Many bats perceive their world mostly through echolocation: they emit a call and listen for the reflected echo, which in turn allows them to "see" what is around them. But if many bats are ...

If you are a parent, then you probably first laid eyes on your child through an ultrasound procedure—the technology that uses high-frequency sound waves to view soft tissue. It is undeniably one ...

That is echolocation. GOLDSHTEIN: So when a bat emit an echolocation call, it wait to the reflected echo in order to get information about the object that is in front of it. And it can get information ...

That’s the one you’ll collide with if you’re not careful. So you change your echolocation in a way that gives you the best detail about that one neighbor, even if everything else becomes ...

Bats navigate using echolocation, which entails emitting a high-frequency sound and then using the bounce-back of the sound waves to gather information about objects in the environment.

For her PhD research, bat biologist Kadambari Deshpande made overnight recordings of bat echolocation calls in the Western Ghats. A “good night” would generate about 30 GB of data from 11 ...
