Abstract: A system for controlling an interior sound of a vehicle phase-changes the frequency of additional sound based on the engine operating state to increase the current density, thereby inhibiting signal distortion by increasing the current density. As a result, the distortion phenomenon caused by excessive use of amplifier current when generating the additional sound is reduced or minimized, and unnecessary noise is inhibited from occurring in a vibration generator and a frame of the vehicle.
