Dept. Electrical Engineering, Institut Teknologi Bandung, Jalan Ganesha 10, Bandung, Indonesia



This paper presents an H estimation approach to active control of acoustic noise inside an enclosure. It is shown how H filter theory and algorithm can be effectively applied to active noise control to provide important robustness property.  Real-time implementation of the algorithm is performed on Digital Signal Processor. Experimental comparison to conventional FxLMS algorithm for active noise control is presented for both single channel and multichannel cases. While providing some new results, this paper also serves as a brief review on  H filter theory and on active noise control.

Keywords: 3D enclosure; active noise control; centralized; decentralized; digital signal processor; H~ filter algorithm; multichannel; single channel.
