N2 - This paper proposes a method for online feedback path modeling in multichannel active noise control (ANC) systems. Previously we have proposed a method for online feedback path molding for single-channel ANC system. Here we modify and extend this method to multichannel ANC systems, in particular, we consider a 1 × 2 × 2 system comprising one reference microphone, two secondary loudspeakers and two error microphones. The computational complexity of the proposed method is lower than the existing methods. Computer simulations are used to demonstrate the effectiveness of the proposed method.
