Female [[mallard]] ducks (as well as several other species in the genus ''Anas'', such as the [[American black duck|American]] and [[Pacific black duck]]s, [[spot-billed duck]], [[northern pintail]] and [[common teal]]) make the classic "quack" sound while males make a similar but raspier sound that is sometimes written as "breeeeze",<ref>{{Cite book|url=https://books.google.com/books?id=VGofAwAAQBAJ&q=mallard+sound+deep+and+raspy&pg=PA39|title=The Duck Bible|last=Carver|first=Heather|date=2011|publisher=Lulu.com|isbn=9780557901562|language=en}}{{self-published source|date=February 2020}}</ref>{{self-published inline|date=February 2020}} but, despite widespread misconceptions, most species of duck do not "quack".<ref>{{Cite book|url=https://books.google.com/books?id=fXJBBAAAQBAJ&q=Females+of+most+dabbling+ducks+make+the+classic+%22quack%22+sound+but+most+ducks+don%27t+quack&pg=PA123|title=Bird Brains: Inside the Strange Minds of Our Fine Feathered Friends|last=Titlow|first=Budd|date=2013-09-03|publisher=Rowman & Littlefield|isbn=9780762797707|language=en}}</ref> In general, ducks make a range of [[bird vocalisation|calls]], including whistles, cooing, yodels and grunts. For example, the [[scaup]] &ndash; which are [[diving duck]]s &ndash; make a noise like "scaup" (hence their name). Calls may be loud displaying calls or quieter contact calls.

A common [[urban legend]] claims that duck quacks do not echo; however, this has been proven to be false. This myth was first debunked by the Acoustics Research Centre at the [[University of Salford]] in 2003 as part of the [[British Association]]'s Festival of Science.<ref>{{cite news | last = Amos | first = Jonathan | title = Sound science is quackers | work = BBC News | url = http://news.bbc.co.uk/2/hi/science/nature/3086890.stm | access-date = 2006-11-02 | date=2003-09-08}}</ref> It was also debunked in [[MythBusters (2003 season)#Does a Duck's Quack Echo?|one of the earlier episodes]] of the popular Discovery Channel television show ''[[MythBusters]]''.<ref>{{cite web| url=http://mythbustersresults.com/episode8| archive-url=https://web.archive.org/web/20070626043438/http://mythbustersresults.com/episode8| url-status=usurped| archive-date=June 26, 2007|title=Mythbusters Episode 8|date=12 December 2003}}</ref>
