Echolocating bats build image-like environmental representations from reflected chirps

Evidence

Species with highly advanced and specialized hearing abilities have evolved, for example the echolocating bat. This animal sends chirps - frequency sweeps - and receives their reflections from surrounding objects. Auditory analysis of the echoes enables the bat to construct an image-like representation of its environment for navigation, even in fast flying. Many animals have a very sensitive, accurate, or specialized auditory system. The hearing system is important as an early warning indicator of dangerous situations or as an aid for hunting. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 65
