PROBLEM TO BE SOLVED: To provide an acoustic controller which can reduce distance attenuation of sound pressure without upsizing the acoustic controller.SOLUTION: An acoustic controller of one embodiment is provided with: a first group of speakers which are driven by a first acoustic signal, radiate a plurality of first sounds, and generate first sound images by composing the plurality of first sounds; a second group of speakers which are driven by a second acoustic signal, radiate a plurality of second sounds, and generate second sound images by composing the plurality of second sounds; and a generation part for generating a first acoustic signal and a second acoustic signal so that a first sound pressure ratio and a second sound pressure ratio of a second control point with respect to a first control point are matched in the first control point and the second control point away from the first control point. In the first sound pressure ratio, a virtual sound source is driven by a target acoustic signal and formed by a third sound radiated by the virtual sound pressure; the second sound pressure ratio is formed by a third sound image into which the first sound image and the second sound image are composed. |
