A new active noise control system is proposed that can selectively cancel a particular noise signal from a mixture. Blind source separation of the desired signal from the other noise signals is performed by a dynamic recurrent neutral network that is used as a preprocessor of this active noise control system. The proposed active noise control system then adaptively generates an anti-noise signal to specifically remove only the separated noise signal. Computer experimental results show that the proposed scheme can be effective in the construction of a selective attention system.
