Abstract

Active noise contral systems for braadband noise reduction require substantial computing power, especially for multichannel systems and adaptive controllers. Furthermore, speed of convergence can be an issue as weil. In this paper, methods and techniques are described that are able to reduce the computational complexity and to improve the speed of convergence. The latter is accomplished by using a control implementation running at multiple sample rates. Decentralised control loops running at high sample rates are efficiently implemented on reconfigurable hardware. For the low to medium sample rates, a full multichannel adaptive control algorithm has been developed that leads to subtantially improved convergence rates at reasonable computational complexity.
