Abstract
It is possible to generate a noise cancel signal appropriate for a device state and a noise state. An external noise collected by a reference microphone (1) is inputted to a feed forward processing unit (3) and a noise cancel control unit (4). The feed forward processing unit (3) includes: a frequency response control unit (3a) for making a filter so as to pass only the component in the control frequency band of the external noise and not to pass the frequency band not contained in the external noise; and a gain control unit (3b) for adjusting the gain of the external noise. A noise cancel control unit (4) includes a parameter acquisition unit (4b) which acquires a parameter according to a detection result of the external noise detection unit (4a). According to the acquired parameter, the frequency response control unit (3a) and the gain control unit (3b) are controlled. An adder (7) adds the noise cancel signal outputted from the feed forward processing unit (3) to a music signal outputted from a sound source (8) and outputs the added signals from output means (10).
