Abstract
An ASC apparatus, which actively generates a sound effect inside a cabin of a vehicle provided with an internal combustion engine and an electric motor as driving sources, includes: a reference signal generating unit which generates a harmonic reference signal based on a vehicle-speed-corresponding frequency, being a frequency based on a vehicle speed, by referring to waveform data; a driver seat speaker which outputs a sound including the sound effect; and a signal processing unit which generates a control signal that forms the sound effect by multiplying the reference signal by a sound effect gain related to the reference signal, and outputs the control signal to the driver seat speaker. The signal processing unit sets the sound effect gain based on a state of charge of a storage battery.
