Animal Planet just put up a random trivia quote saying a wolf's howl doesn't echo. Is that really true or is it like a duck's quack that echoes at a frequency so low we humans just can't hear it?

Any sound will echo in the right circumstances. To get a single echo, you must have something that reflects the sound with a delay, while for a multiple echo, there must be more than one reflecting surface. As to ducks, see http://www.snopes.com/critters/wild/duckecho.htm There is absolutely no reason why a wolf howl would not echo if the wolf howls in a place that echoes. Probably, in the wild they do not howl in places that echo. Forests tend to be sound absorbers rather than reflecters. Feb 28 07, 9:07 AM
