Abstract

Realization problem of active noise control system is studied in the article. The foundational theory and algorithm of active noise control are introduced, the feed-forward adaptive active noise control (AANC) system is presented, the hardware solution of the system is proposed by selecting TMS320VC5509 DSP as the controller. Using the C language, the active noise real-time control system is realized, based on the FX-LMS algorithm. It´s proved that 12dB cancellation on 800Hz is achieved by the experiment.
