Have you ever checked that? Only asking because I'd never heard of such a thing before I arrived in England. I haven't conducted any formal experiment on English ducks, but I can assure you that the French "Coin-coin" (kwah kwah in phonetics, kind of duck's French accent) is definitely resoundant!

Of course the quack has to echo - ye cannae chaange the laws of physics Jim!

In the absence of an echoey tunnel, the duck emits another quack as soon as the echo is detected back at it's ears. The follow-up quack is made in phase with the returning echo and the waveforms merge, thus amplifying the apparent sound of the duck. An echo would normally be diminished in amplitude(volume) each time it is heard so the duck is hiding the normal physical experience of an echo.QED!

Sneaky webbed feet, billed G*ts!

I've never trusted ducks since that dooby fella and his disco bus.

I might be sailing it, but it's still sh**e!
