Research on the Technique of Active Noise Control Based on DSP

以自适应有源噪声前馈控制系统为研究核心,选用TMS320F206 DSP作为控制器,给出了系统的硬件解决方案,并利用汇编语言在硬件系统上实现了基于DLMS算法的有源噪声实时控制。实验结果表明,系统取得了良好的降噪效果。

The feed-forward adaptive active noise control （AANC） system is presented. Firstly, the hardware project of the system is brought forward, by selecting TMS320F206 DSP as the controller. Then, using the assembling language, the active noise real-time control system is realized, based on the DLMS algorithm. It＇ s proved that a good noise cancellation is achieved by the experiment.
