title = "Active noise control over 3d space with multiple circular arrays",
abstract = "Spatial active noise control (ANC) systems focus on minimizing unwanted acoustic noise over a continuous spatial region. Conventionally spatial ANC is attempted using MIMO system and recently novel methods have been developed using spherical harmonic analysis of spatial sound fields. A major limitation for implementing the latter approach is the requirement of regularly distributed microphones and loudspeakers over spherical arrays. In this paper, we relax the above constraint by constructing a system utilizing multiple circular microphone and loudspeaker arrays, and by designing a feed-forward adaptive filtering algorithm for noise reduction over a 3D region. By simulation, we demonstrate that the proposed method can achieve comparable ANC performance to conventional spherical array methods, while being more feasible to be implemented in practice.",
