Current approaches for active noise control in large listening spaces require a high number of sensors to control the sound field within a given volume. This contribution presents a new approach based on the theory of acoustic wave propagation. It exploits the fact, that a distribution of sources and sensors on the boundary of the listening space is sufficient for global control of the enclosed field. This principle has already been successfully exploited for spatial audio reproduction and is now applied to active noise control. Theoretical considera- tions, simulations, and measurements with a wave field syn- thesis array show that this approach is capable of consider- able noise reduction in low-reverberant enclosures. Exten- sions to listening spaces with higher reverberation times are straightforward but require an increased number of output channels. |
