Mode Domain Spatial Active Noise Control Using Sparse Signal Representation

Maeno, Yu; Mitsufuji, Yuki; Abhayapala, Thushara


Active noise control (ANC) over a sizeable space requires a large number of reference and error microphones to satisfy the spatial Nyquist sampling criterion, which limits the feasibility of practical realization of such systems. This paper proposes a mode-domain feedforward ANC method to attenuate the noise field over a large space while reducing the number of microphones required. We adopt a sparse reference signal representation to precisely calculate the reference mode coefficients. The...[Show more]
