Can noise cancellation be explained with a particle model of air?

The noise sound
is an energy source. Generating an inverted sound on the
drums of the speaker is also an energy source (from the
electricity which powers the speaker). So the total energy
output cannot be zero. But we hear silence! Where does
that energy go?
: I'm more interested in a theoretical answer, assuming
a perfect world with no energy loss in converters / out-of-
sync waves. Although an answer giving real world
converter efficiencies is also useful.
