ABSTRACT:
A noise controller which noise-controls a movable point so that a noise generated from a noise source and transmitted to the movable point can be reduced. The noise controller filters the noise in accordance with a least mean square algorithm and generates an antinoise to be collided with the noise so that the antinoise and the noise can cancel each other out. When a filter coefficient used for the least mean square algorithm is renewed, the noise controller uses position data of the movable point. Thus, even if the movable point moves, the proper noise-control can be performed.
