摘要：
Nowadays, there are many commercial ANC (Active Noise Control) headphones using either digital signal processors (DSPs) as control unit to implement the feedback FXLMS algorithm, or analog circuit by using control theory's feedback structure to cancel the noise in active way. However, for DSP's product, it's much expensive than conventional passive headphone. As a result, this paper proposed using a micro-controller unit (MCU), Cortex-M4, instead of DSP to implement the adaptive algorithm in headsets. Experimental results illustrate the digital control ANC headsets' performance with commercial headset to verify effectiveness.
