"So a duck's quack certainly echoes around our reverberation chamber, so a duck's quack does echo.
Which leads to the most interesting question, why did the myth arise?
The are a few possible explanations that I can think of:
The quack does echo, but it is usually too quiet to hear.
When you want to hear an echo, you usually make a very loud noise to make sure the reflection can be heard.
But a duck quacks too quietly, so the reflection is too quiet to hear.
Ducks don't quack near reflecting surfaces.
You need a large reflecting surface, a mountain or building for the sound to reflect off.
Maybe ducks don't hang around reflecting surfaces.
It is hard to hear the echo of a sound which fades in and fades out."
