Bats & Echolocation

Did you know bats send out sounds from their mouths to know exactly where to go? This emitting of signals is called echolocation, and they are essential to its flight. As it flies, high-pitched noises are emitted at the rate of 30 per second. As the echoes are bounced back from objects, the bat sends out more signals at the rate of around 60 per second. This echo is like a messenger, telling the bat the location, size and shape of obstacles and allows the bat to avoid collisions.
