I am sure this is a complete science myth.
A duck's quack does not echo.
How can I verify/falsify this without getting a duck?

Probably not. Can you quack like a duck? (And if so, do you walk
like a duck? Do you LOOK like a duck?)

Does sound echo?

Not usually, as far as I can tell.

Is a quack a sound?

Yes.

If the answer is yes to both questions,

Dang ...

Come to think of it, I've heard ducks quack but I've never heard a
quack echo.
