Bats Hear Just Fine, Despite Noisy Lives

[Still Waters]

Bats live noisy lives, often surrounded by sound, but they're not complaining: They're unaffected by the din, according to a new study out of Brown University on bat hearing.

The furry fliers use echolocation to make a nocturnal living, emitting high-frequency sounds and using the returned echoes off of objects to both navigate and hunt at night, mapping the world in front of them - whether tasty insects or physical obstacles - with "pictures" created out of sound.

That can get pretty loud, if you're a bat.

I am confused! (not a shock to members here I know)

"Blind as a bat." Never read anything about bats having hearing issues.

"Deaf as a post." Are they going to study the eyesight of a post now?
