The sound volume control device is connected to output units symmetrically arranged with respect to left and right seats of a vehicle. The sound volume control device estimates a common frequency to be controlled when sounds outputted from each of the output units are listened to at each of listening positions of the left and right seats, and corrects a level at the common frequency based on the common frequency. Preferably, a frequency at which the direct sounds of the sounds outputted by each of the output units become in-phase at the listening positions of the left and right seats is determined as the common frequency based on the distances from each of the output units to one of the listening positions of the left and right seats.
