Since the ultra-compact electric vehicle does not generate an engine sound, an interior noise caused by road and wind noise have a large impact on user comfort in the interior space. In this study, we propose a system whereby giant magnetostrictive actuator is installed on the front window 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. Also, we studied fundamental consideration of masking. In this study, we evaluate the vehicle interior comfort by using living body information measured the brain waves of the crew.
