How does active noise cancellation work? And where does the sound energy that gets cancelled end up?

0

More specifically: when I wear those active headphones, the speakers put sound into the headphone and this cancels out the noise from outside. But now there is a bit more sound energy than there was before: the sound energy that was there, plus the energy from the loudspeakers in the headphone. Where does it go?
