|MadSci Network: Other|
This would probably come somewhere between "acoustics" and "zoology". Several friends have sent me a list of "fun" trivia which is making the rounds on the Internet these days. Most of the items are true, some are clearly false, but one particular item is particularly annoying, because I've been unable to find anything on the Internet which supports or refutes it: "A duck's quack doesn't echo, and nobody knows why." This definitely smacks of a fabrication, as sound is sound, and sound bounces off any hard surface-- doesn't it?. The "nobody knows why" part is particularly egregious, as I think we know quite a bit about sound-- don't we? Ducks don't have "stealth quacking technology"-- do they? Not that I've seen many ducks standing at the mouths of box canyons quacking loudly, but still...
Re: A Duck's Quack Doesn't Echo? Surely a hoax?
