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.

We typically imagine echolocation as “seeing” with sound—experiencing auditory signals as a world of images like the ones our ...

For these animals, sonar can replace other senses, such as sight or smell. Without echolocation, they would struggle to find food, avoid predators, or navigate safely, making survival difficult.

As a form of echolocation, the wing method was fairly rudimentary, they found. "We found that even if you put quite large obstacles, wires that were two centimeters [about 0.8 inch] in diameter ...

Like sonar, echolocation works by projecting sound and listening to the reflection it makes when it hits the different objects of the environment.

In case you didn’t already think that bats’ ability to navigate with their ears instead of their eyes was cool enough, get this: Mexican free-tailed bats can actually use biological sonar to ...

A new brain-imaging study of human echolocation is making headlines after 45-year-old Daniel Kish of Long Beach, ... The Return of Sonar Boy America learns, yet again, ...

And human echolocation has also attracted the attention of academic researchers. One group in Spain determined in 2010 that tongue clicking was more successful than snapping or clapping .

Though echolocation is a relatively primitive trait, existing since at least 50 million years ago, researchers are still discovering new complexities about the sonar system.

Bats map the world around them using echolocation. New research shows that an echo's strength doesn’t tell bats the size of objects, and instead they use sonar aperture.
