| Abstract: | The foundational theory and algorithm of active noise control technology 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 9dB cancellation on 800 Hz is achieved by the experiment. |
