Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes an active noise control (ANC) system reducing periodic noises generated under the high-field area such as a noise generated from magnetic resonance imaging (MRI) device (we call MR noise). The proposed ANC system utilizes optical microphones and piezo-electric loudspeakers because specific acoustic equipment is required to overcome the high-field problem, and is formed by a head-mounted structure to control noise near user's ears and make up for the lack of output level of the piezo-electric loudspeaker. Moreover, the internal model control (IMC) based feedback ANC is employed because the MR noise consists of some periodic components and is predictable. Some experimental results demonstrate that the proposed ANC system (head-mounted structure) can significantly reduce the MR noise by approximately 20 dB even if the imaging mode changes frequently under the high-field in an actual MRI room.
