In the 2003 season of Mythbusters (a US show) they discovered that a ducks quack has the same type of waveform as it's echo. So, the echo is indistinguishable from the original sound.

Now, I've not heard this anywhere else, and their 'echo chamber' was just an open field with a line of trees at one end, so I'm suspicious. Has anybody else heard this confirmed or disproved in more rigorous studies?

One googles 'duck quack echo' and one gets this.

Another well-known TV show has this to say:

Quote:
Internet-lore notwithstanding, there is nothing special about a duckís quack to stop it from echoing. This was proved at the University of Salford by placing a duck in a reverberation chamber. It is possible that this much-repeated myth originated because ducks donít make loud noises so the echo is often too quiet to be heard.

I think it got garbled in translation. I understand the original CHinese axiom was that no one had ever heard the echo of a peking duck (no matter how hoi it's sin might have been).

HTH,
