Today's lesson on sound physics: Phase Cancelation

When two sound waves are the exact inverse of each other, they cancel  out. This is what noise cancellation headphones do. They listen to the sound outside and play it back to you 180 degrees out of phase. The result is perceived silence.

What I want is a phased array that can do targeted cancellation. Silence, but only for that one guy over there in the corner.
