Abstract
A vehicle acoustic control device includes: a plurality of speakers disposed on a periphery of a passenger; and a controller that controls a sound field in a vehicle cabin by individually driving the plurality of speakers. The controller rotates and displaces the sound field in a direction opposite to a changing direction of a vehicle behavior. At this time, when a frequency at a time of change of the vehicle behavior is higher than a predetermined frequency, the controller changes the sound field in the vehicle cabin in the direction opposite to the changing direction of the vehicle behavior, and increases a variation of the sound field as a variation of the vehicle behavior is being larger.
