A technique used by some animals to locate the position of objects around them, by producing sounds and listening to their echoes.

A technique used by some animals to locate the position of objects around them, by producing sounds and listening to their echoes. The time it takes for the sound to come back gives an indication of distance. Many bats can fly and even hunt in complete darkness, using bursts of high-frequency sound, beyond the range of human hearing, to orientate themselves. Dolphins and some whales also use a form of echolocation.
