Can anybody tell me why a ducks quack is the only natural sound that will not echo?

Answer 1

it does echo, it was proven on "mythbsters" it's just heard to hear the echo

Answer 2

The sound waves move in a highly spread, wide angled path; the shape of the duck bill causes the distribution of waves to be so wide and dispersed, that they peter out at a very short distance from the duck.
However, sound waves are sound waves, and sound waves echo. So if the duck quacks at point A and it's close enough to a wall at point B there will be an echo. And if you are close enough to point B, you will hear an echo.
And if you happen to be a cat you will be in luck! You will have penetrated the poor duck's natural defense.
Chow time!!! Meow!!!!!!!!!!!! Quack?! QUACK!!!!!!!!!!!
