Ducks Quack and Echoes: British Study Confirms

[Phobos]

QUACK...quack quack

http://www.cnn.com/2003/TECH/science/09/08/duck.quack/index.html

A British study has debunked an urban myth -- that a duck's quack does not echo. ...The tests revealed that a duck's quack definitely echoes, just like any other sound, but perhaps not as noticeably.

...quacked me up!
I love the duck at the mic shot.

I'm sorry, I confused about what's
been debunked here. Is it still
true that in space no one can hear
you quack?

I love the duck at the mic shot.

Me too.

My question is; will that duck float?

---if it quacks like a duck, it's probably an echo!

And if it does, is it a witch?

We need some conspiracy-theorists in here; this thing stinks of an international cover-up!

Seriously though, what do they mean by,

...by first recording Daisy's quack in a special chamber with jagged surfaces that produces no sound reflections.

She was then moved to a reverberation chamber with cathedral-like acoustics before the data was used to create simulations of Daisy performing at the Royal Albert Hall and quacking as she flew past a cliff face...

?

Did they actually record the duck in the reverb chamber, or just play the recording of the duck, thus proving that there speakers produce an echo in a reverb chamber?

So you really think that they're ducking the issue?
