It would be possible if you had a matrix of speakers covering all walls & ceiling. In that scenario you could control the entire sound landscape across the board, and cancel out or simulate arbitrary sound sources in the room.

It would take gigantic processing power, but it's theoretically possible.
You'd have to run realtime 3-D FFTs on the sound in the system, at approximately a few kHz.
