Abstract(in English) To achieve a sound field reproduction system, it is important to design multipath inverse filters which cancel the effects of room transfer functions. Additionally, there are two control points, which is left and right ear, from a loudspeaker. Accordingly, a loudspeaker have to deal with multi-path by one control system. Moreover, acoustic characteristic of the human ear is used because system is assessed by human. Consequently, in this paper.inverse filter, which parameters is updated with weighted sensitivity function, for multi-input system is designed. Furthermore, this sound field reproduction system by this method is simulated by computer.
