Bats' echolocation recorded and recreated

A team of British researchers has worked with six adult Egyptian fruit bats to record and recreate their calls. These calls are pairs of 'clicks' from the bats' tongues that they use to fill their surroundings with acoustic energy; the echoes that return allow the bats to form an image of their environment.
