why does a duck's quack not echo?

[ilikemonkeys]

I've always wondered this......

 

[Jam_Master_J]

They experimented with this on the "Mythbusters" tv show. It was established that the echo exists but is difficult to distinquish from the initial quack.

Here's a resource.

Short answer:

They do echo...

Here what University of Salford did on duck echo with mp3 sample it does echo but like Jam_Master_J said it can be hard to distinguised without non-echo reference first but you can easly hear it if you A/B with the non echo refecence

Hahah, I don't know why but I just find it amusing sticking that duck in a large chamber all by itself for recording its echo.

My duck's quacks don't echo because he doesn't quack; he hisses

Exactly. Duck quacks aren't excluded from the laws of physics & sound waves.

You need to return your duck to the store then, sounds like they sold you a snake by accident..

Of course a duck's quack echos. All sounds do.

You have a duck?

Show us a Pic, and give us his name or her name

If you were bored enough you could practice making it so that you make two noises and that when the one reflects the 2nd noise cancels it out...

but you have to be REALLY bored to do that...

My Duck's name is Bill, he is a male muscovy about 3 years old.
He's pretty big, I think around 15lbs or so. He's about twice the size of a regular duck.

Here is a pic of my duck.
Here is a picture of the duck and I.

There is a place on Queens Blvd in NY under the 7 train tracks that has these arches that echo like crazy. I bet a duck would echo there. I should get a live duck, video tape its echoing quack, and sell it to a chinese restaurant 15 minutes later. I could then sell a portion of the tape to mythbusters and the second portion of the tape to faces of death.

So...is that your theory about why ducks' quacks don't sound like they echo, they were bored?
