Design and Implementation of Adaptive Active Noise Cancellation Headset System Based on DSP

Design and implement the adaptive active noise cancellation headset system based on DSP is proposed. The principle of active noise cancellation headset system is analyzed, and then the hardware and software of the adaptive active noise cancellation headset system are implemented based on SEED-DEC6416 development board, and the program to ensure real-time processing of the system is optimized. The noise cancellation headset system realizes the extraction, adaptive filtering and noise cancellation of the noise signal. The results indicate that the noise can be canceled in the noisy environment and the voice signals can be restored well, and the feasibility of the system and the correctness of algorithm are verified.
