Abstract: A sound system for a vehicle including an engine and an audio device for an internal space of a cabin as sound sources disposed at given positions of the vehicle is provided which includes an engine sound localizer configured to localize a first sound generated by the engine to cause a vehicle driver inside the cabin to hear the first sound from a first position, and change the first position, and a traveling state detector configured to detect a traveling state of the vehicle. The engine sound localizer normally sets the first position at a default position and, when a given traveling state is detected by the traveling state detector, changes the first position to a specific position at which the vehicle driver is able to recognize the engine sound more clearly than at the default position.
