Abstract
A volume control device for controlling a volume of an audio system includes a volume control unit and a volume resetting control unit. The volume control unit executes a volume control when a reception of an incoming call by a telephone is detected while an audio device of the audio system is in use. Here, the volume control unit changes the volume of the audio device from a present level to a first level that is lower than the present level. The volume resetting control unit executes a volume resetting control when an end of a call by the telephone is detected. Here, the volume resetting control unit changes the volume from the first level to a second level if the present level exceeds a reference value.
