Abstract
A technology for controlling acoustic energy distribution in a control region is provided. A sound processing apparatus includes a control filter such that a controllable sound zone is formed in the control region, and the sound processing apparatus synthesizes the control filter and an input signal to transfer sound to a desired location or a specific user. The numbers, the size and the locating positions of the sound zone and/or the control region may be controlled.
