Original Abstract Submitted
A cancellation device according to one aspect of the invention is a cancellation device that cancels noise coming to a region in a vicinity of a loudspeaker, the cancellation device including at least two loudspeakers and one reference microphone , in which the cancellation device is configured such that an acoustic signal emitted in a sound emission direction of a same loudspeaker and an acoustic signal emitted in an opposite direction collide with each other, the at least two loudspeakers and the reference microphone are arranged on a same plane, the at least two loudspeakers emit cancellation sound that cancels the noise in synchrony, and the plane is a plane including a boundary between a sound emission direction of the two loudspeakers and a direction opposite to a sound emission direction.
