ech·o·lo·ca·tion

(ek'ō-lō-kā'shŭn),
Term applied to the method by which bats direct their flight and avoid solid objects. The creatures emit high-pitched cries that, though inaudible to human ears, are heard by the bats themselves as reflected sounds (echoes) from objects in their path.

echolocation

the means by which objects are identified through echoes returned from very high frequency sound emissions. Bats use such a system to avoid objects in flight and to locate prey, as do toothed whales and dolphins.

The first experiment revealed that untrained sighted participants can quickly learn to echolocate.
By virtue of being mobile when they echolocate, dolphins are able to perceive objects from multiple points of view.
But the well-preserved fossils reveal the primitive bat's inner ear was small, which suggests that it could not echolocate.
Other bats use tongue clicks to emit sonar signals and some do not echolocate at all.
In searching for moths, barbastelles echolocate at about the 94 decibel level, roughly the equivalent of a busy highway, Goerlitz reports.
Washington, January 25 (ANI): In a new international study, scientists have used 3D imaging to shed new light on the way bats echolocate.
The consensus seemed to suggest that bats learned to echolocate (use sonar to determine their location in space) first--presumably while sitting on tree branches--and only later learned to fly.
They don't necessarily need their vision to fly or catch insects because they are also able to echolocate.
The fossil record of these delicate-boned creatures is sparse, but analyses hint that even the earliest known bats--those flitting through the skies between 54 million and 50 million years ago--could echolocate, says Nancy B.
Some echolocating species have close relatives that apparently possess the anatomical means to echolocate but don't use it, implying that avian echolocation is a behavior that some species simply haven't learned.
Thanks to this ability to echolocate, they "see" in much finer detail the scene that the goggles present to me.
