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?
I don't think you can. In science, the only acceptable way to
verify/falsify is to subject the hypothesis to *physical testing*,
n'est-ce pas? Find an environment that produces echoes of other sounds,
and bring on the ducks.
On the Phys-L list, Rondo Jeffery replied to Tim:

This is a joke, yes? You're poking fun at the Aristotelian "science"
that went out of fashion prior to the 18th century? We all know what a
price Galileo and others paid, to get us free from this approach and get
us onto the path of experimentation.
Do birds fly through the air?
Is a penguin a bird?
If the answer is yes to both questions,
Then a penguin flies through the air.
