A duck's quack doesn't echo, and no one knows why.

Can physics explain this fact and how?
Ducks quack as a form of communication, usually to attract mates or to warn other ducks of danger. Male ducks also use quacking to establish dominance.
Contrary to popular belief, a duck's quack does actually echo. The reason it may not be as noticeable is because the quack is usually at a low frequency and the echo is not as distinct as higher frequency sounds.
Yes, ducks are able to hear their own quack. They have excellent hearing and rely on their quacks to communicate with other ducks.
No, not all ducks quack. Some species, such as the male mallard, have a characteristic quack, while others, like the female mallard, have a more raspy call. Some duck species, like the mute swan, do not quack at all.
No, the myth about a duck's quack not echoing is not true. As mentioned before, a duck's quack does echo, but it may not be as distinct as other higher frequency sounds.
