Baboons using sound for echolocation in caves

BBC Television has recently shown the use of sound as a simple form of echolocation in caves by primates. Chacma baboons in the southern Cape of Africa are known to sleep in caves, and call to one another in order to navigate their way around in the pitch dark (Monkey Planet, Episode 1, “Meet the Family”, BBC Television, first shown 2 April 2014).

Humans are not Baboons, but if primates use these techniques then it is an indication of the usefulness of sound in caves for navigation.
