Abstract:
The present technology relates to a locally silenced sound field forming apparatus and method, and a program capable of controlling a silenced area in a depth direction. The locally silenced sound field forming apparatus includes: a first speaker array that outputs a sound on the basis of a first speaker drive signal to form a predetermined sound field; and a second speaker array arranged at a position different from the position of the first speaker array and that outputs a sound on the basis of a second speaker drive signal to form a sound field that cancels the predetermined sound field. The present technology can be applied to a locally silenced sound field forming apparatus.

Claim (Index 5):
The locally silenced sound field forming apparatus according to  claim 3 ,\n wherein the drive signal generation unit generates a first spatial frequency spectrum of the first speaker drive signal on the basis of the first distance and generates a second spatial frequency spectrum of the second speaker drive signal on the basis of the second distance, and the locally silenced sound field forming apparatus further comprises: a spatial frequency combining unit that performs spatial frequency combining on each of the first spatial frequency spectrum and the second spatial frequency spectrum so as to generate a first temporal frequency spectrum and a second temporal frequency spectrum, respectively; and a temporal frequency combining unit that performs temporal frequency combining on each of the first temporal frequency spectrum and the second temporal frequency spectrum so as to generate the first speaker drive signal and the second speaker drive signal, respectively.
