Ducks and Quacks

Keeping up the tradition of posts that contain interesting but ultimately useless facts and information, I have this to add:

A duck's quack does not echo!

I do not know who engages in this kind of scientific enquiry and the importance of knowing such information. Nevertheless, who am I to judge such endeavours?

Someone should update the questions on trivial pursuit because I am sure to be a legend in my own lifetime :D

Who told you that? Any sound will make an echo under the proper conditions.
I will happy to demomstrate if you provide the research funding.

Finally busted...

The factoid was taken from a questionable source; the underside of a bottle cap :D

However, as PJB has pointed out, under teh right conditions a duck's quack does in fact echo. The echo though remains faint but nevertheless the urban legend in this case has been proven false.

See this link, http://www.sciencemadesimple.co.uk/page29g.html, for further details as to the fallacy of the non-echoing duck quack.
