I heard a report on the CBC science show about anti-noise just a few weeks
ago.  Most of the report involved a Canadian or US company whose name I 
don't remember.  It seems that they already have an anti-noise device
which uses headsets and is intended for pilots.  They have a research
contract for developing a replacement for mufflers (silencers, if you
will) for cars.  This prototype system is not very successful, but
they are still working on it.
