SOUND FIELD REPRODUCTION SYSTEM, SOUND FIELD REPRODUCTION METHOD, AND SOUND FIELD REPRODUCTION PROGRAM

摘要

To accurately control sound pressure of a plurality of types of sound information so that one of the plurality of types of sound information can be heard independently at each of a plurality of areas.SOLUTION: A sound field reproduction system comprises: a plurality of first speakers and a plurality of second speakers; and an application unit for applying a set of a transfer function for a first filter and a transfer function for a second filter forming a pair. The pair of the transfer function for the first filter and the transfer function for the second filter has a first control point and second control points set for each of a plurality of areas, the first control point targeting a first frequency band, the second control points targeting a second frequency band higher than the first frequency band, the number of the second control points is larger than the number of the first control point; and has values set for controlling sound pressure of a plurality of types of sound information at the first control point and the second control points so that one of the plurality of types of sound information can be heard independently at each of the plurality of areas.SELECTED DRAWING: Figure 8
