In conventional vehicle, the noise generated by engine mainly deteriorates cabin comfortability. However, in ultra-compact electric vehicle which does not include engine, an interior noise caused by road and wind noise have a large impact on user comfort in the interior space. In previous study, we propose a system whereby giant magnetostrictive actuator is installed on the roof of an ultra-compact electric vehicle to actively cut interface vibration noise, i.e., road noise, transmitted to the interior of the vehicle and we aim to reduce the noise level in an interior of a vehicle using this proposed active noise control system. Furthermore, we studied fundamental consideration of masking. In this study, we focused on 1/f fluctuation for masking music and evaluate the vehicle interior comfort by using the brain waves of the crew, in the case of operating driving simulator.
