This vehicle acoustic control device is provided with a plurality of speakers (23) positioned, in a plan view, so as to surround passengers, and a controller (21) that controls a sound field in a passenger compartment by individually driving the plurality of speakers (23). The controller (21) sets a reference yaw rate (gamma N) associated with a driving input, which changes the motion of a vehicle, and detects the actual yaw rate (gamma R) of the vehicle when the driving input has been implemented, and rotates the sound field inside the passenger compartment in the direction in which the motion of the vehicle actually changes, according to the deviation (delta gamma) of the actual yaw rate (gamma R) with respect to the reference yaw rate (gamma N). In other words, a change in the turning motion associated with the driving input is produced before the turning motion actually changes.
