Duck quacks do echo

Mythbusters has disproved the statement that a duck's quack doesn't echo:

"A duck’s quack does not echo.

When examined by an audio-expert, it was found that the echo was "swallowed" by the original quack, due to the very similar acoustic structure between the quack and the echo. Because of this, it may be difficult to tell where the quack ends and the echo begins."
