Abstract
A sound control device controls an interior sound in a vehicle based on a slope of a road on which the vehicle travels. The sound control device includes: a sound canceling circuit for generating a first correcting sound for lowering a level of an interior sound measured in the vehicle; a sound boosting circuit for generating a second correcting sound for increasing the level of the interior sound; and a controller for setting a level of a second target sound to be less than a level of a first target sound. In particular, the second target corresponds to a ramp in which an absolute value of the slope is greater than a reference value and the first target sound corresponds to a flatland in which the absolute value of the slope is equal to or less than the reference value.
