| Abstract(in English) | We propose a new sound field reproduction system, where the system can give the accurate sound image of the observed signal at the primary field if a user is at a specific place, and the system can provide the direction of the primary source if the user moves from the specific place. The conventional method does not care about the accurate reproduction outside the specific control points, and if the user moves from the control points, he cannot feel the sound image. To solve this problem, we find the solution of inverse filter that makes the power of the specific secondary source largest. In the proposed method, the user can feel the sound image toward the enhanced secondary source even around the control points. Simultaneously the accurate reproduction at the control points can be achieved as well as the conventional method. The experimental results can show the robustness of the proposed method against the user's move in comparison to the conventional method. |
