The obstacle is fairly simple. If the WFS is only one "wall" of the room, it can only reproduce wave fronts traveling away from that wall into the room. The unwanted wavefronts are traveling into other directions and can't be canceled by any waves you generate from the "WFS wall". Your only solution would be to cover all six surfaces with transducers. Then you could do it. |

The insight that the 4 adjoining walls provide mirrors that virtually extend the front array is a valuable one. What it cannot do is offer separate control over waves travelling from the back wall to the front wall. The idea seems to work for reflections off the ceiling, floor and side wall, but I can't see how you control anything coming off back wall. |

Unfortunately, distinction between theory and practise is, in theory no distinction between theory and practise exist, yet in practise though. |
