Does A Duck's Quack Echo?
I have read in many places online that a Duck's Quack cannot echo, is this true?
From everything that I have heard both on line and in books the Quack of a duck does not echo. I do not know how hard this has been tested but I know there are sounds because of the pitch or frequency they do not produce and echo. The duck may be in that catagory.

There was a short experiment done with a duck to test this theory. Before doing the experiment they admitted that everywhere online it says that a duck's quack does not echo, but this was proven to be false. The reason it may sound like a duck's quack does not echo is because ducks are not in locations where an echo can be heard and the volume of their quack may not be loud enough to detect it, but it is possible.

Comments: Apparently a duck's quack doesn't echo. My psychology lecturer told us as such. I can't remember why!
