or rather plays the same frequency but completely out of phase (180 degrees) so it get cancelled out?
Its phase cancellation.. im sure wiki has a short crash course in this concept, as i don't feel like explaining it (plus wiki or other resources would have it written up better than me).
That's what your after if your asking how this is theoretically done. |
