Design and Realization of an Active Noise Control System Based on DSP

摘要：

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 FXLMS algorithm. Its proved that 12dB cancellation on 800Hz is achieved by the experiment.
