Re: the lowest natural sound yet detected

There was a contentious debate about this story on the phonography list;
the upshot is that this is definitely a sound as physics defines it
(propagation of pressure waves through a physical medium, in this case gas
-- NOT vacuum)...

...but some members of the list took issue with whether ultra- and infra-
sound not "hearable" is "really" sound.

(Personally, I have no problem saying that infra- or ultra- sound with
frequencies orders of magnitute below or beyond the range of *human*
hearing is still "really" sound...)
