No Echo?

So a little birdie told me that a duck quack doesn't echo.

Is this true?

This might not seem important to most people but to me?...yeah it's still not important. Important enough to get the bottom of this question but not important enough to spend TOO much time on it. It's cool though. Especially because I live in a town oriented around ducks and this is the first time I heard about this question. Wierd right?

Is it true? Do Duck Quacks not echo?

Reaserch says: Yes they do echo. Sorry guys, I was voting for not also.

Here's what scientists (or whoever writes this stuff on the internet) are saying.

"Professor Trevor Cox and a team at Salford University recently did some research to get to the bottom of the problem with the help of willing volunteer, Daisy the duck. They found that a duck's quack does echo, but it is quite hard to hear the echo because of the quality of the quack sound. A sound that fades in and out (like a duck quack) makes an echo which can become mixed up with the original sound being made. This means it is hard to distinguish one from the other.

The other reason the myth may have arisen is because you don't often find ducks hanging around places where you commonly get echoes, like cliffs on a beach, or large cathedrals!"

So sorry guys but it looks like a Ducks Quack does infact echo, but HEY! If you don't believe me...go find a duck and check I guess.
