A noise control device eliminates a possibility that a noise arriving at a control point is increased as compared to a case where noise control is not performed and has a reduced circuit scale. The device includes a controlling noise detector for detecting a given noise to output a controlling noise signal, a controlling filter section for signal-processing the controlling noise signal, by using a preset fixed filter coefficient, to output a control signal, and a control speaker for reducing the given noise, by emitting toward the control point a control sound based on the control signal. The device also includes a noise determination section for determining whether the given noise is a noise corresponding to the fixed filter coefficient, and an output control section for stopping output of the control signal from the controlling filter section when the given noise does not correspond.
