CLAIM: Duck quacks do not echo.
ANSWER: FALSE.Urban legend has long had it that duck quacks don't echo. But researchers have disproven this by actually placing ducks in echo chambers and recording the echo of their quacks. Specifically, in 2003 researcher Trevor Cox placed a duck called Daisy in a reverberation chamber and measured the echo of her quacks. Cox explained that a quack is a 'fading sound' and therefore the echo is sometimes a little hard to hear, but it's definitely there.
