Active Noise Control over Space: A Subspace Method for Performance Analysis

Zhang, Jihui (Aimee); Abhayapala, Thushara; Zhang, Wen; Samarasinghe, Prasanga


In this paper, we investigate the maximum active noise control performance over a three-dimensional (3-D) spatial space, for a given set of secondary sources in a particular environment. We first formulate the spatial active noise control (ANC) problem in a 3-D room. Then we discuss a wave-domain least squares method by matching the secondary noise field to the primary noise field in the wave domain. Furthermore, we extract the subspace from wave-domain coefficients of the secondary paths and...[Show more]
