N2 - In the present paper, we propose a sound field control system that controls a wide area in the room by reducing the influence of the reproduction field using Power Envelope Inverse Filtering (PEIF). The envelopes of the room impulse response have approximately the same shape. Therefore, there is a possibility that the proposed sound field control system can control a wider area with a small number of control points by reducing reverberation in the room based on envelope processing. We demonstrate experimentally that the proposed system can control a wide area in the room using PEIF. The results indicate that the proposed system can control a wide area of the room, as compared with Minimum Phase Inverse Filtering (MPIF), which is a typical technique for reducing reverberation. Moreover, the proposed system was demonstrated to be effective in the high-frequency range.
