This vehicle acoustic control device is provided with a plurality of speakers (23) positioned in front of and behind 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 acceleration/deceleration speed (GxT) associated with a driving input, which change the acceleration/deceleration motion of a vehicle, and detects the actual acceleration/deceleration speed (GxR) when the driving input has occurred, and displaces the sound field in the passenger compartment in the direction in which the acceleration/deceleration motion of the vehicle actually changes, according to a deviation (delta G) between the actual acceleration/deceleration speed (GxR) and the reference acceleration/deceleration speed (GxT). In other words, a change in the acceleration/deceleration motion associated with the driving input is produced before the acceleration/deceleration motion of the vehicle actually changes.
