SOUND FIELD REPRODUCING DEVICE, SOUND FIELD REPRODUCING METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a sound field reproducing device capable of reducing the number of speakers to be used for spatial multi-zone sound field reproduction.SOLUTION: The sound field reproducing device includes: a reflection member which is formed to shield a predetermined area and of which the inner face is defined as a reflection plane; and directional variable speakers disposed on a circumference of a circle that is positioned within the predetermined area, and each configured by including a plurality of non-directional sound sources. Weights of the non-directional sound sources are preset in such a manner that a desired sound pressure is reproduced at a plurality of observation points within a plurality of control areas positioned inside of a control area arrangement enabled area that is an area preset inside of the circumference, and the non-directional sound sources are driven based on the weights.SELECTED DRAWING: Figure 1
