Abstract
A vehicle speed detecting unit detects a vehicle speed. A threshold changing unit changes a threshold in accordance with the vehicle speed detected by the vehicle speed detecting unit, A gain calculating unit calculates a gain value of an input sound inputted to a microphone. A sound control unit mutes the input sound when the gain value of the input sound is equal, to or greater than the threshold changed by the threshold changing unit, the gain value being calculated by the gain calculating unit.
