摘要: 
在實際的主動噪音控制應用中,誤差麥克風會量測到與主噪音相關的訊號(相關噪音)和干擾訊號(不相關噪音),當干擾隨著誤差訊號一起進入控制器中,控制器的權重更新會被影響,進而降低主動噪音控制的消音性能(消音量和消音速度)。為了改善不相關噪音對主動噪音控制系統的影響,本文提出了一改良的混合式主動噪音控制,同時對抗相關與不相關噪音,並使用最佳可變步階,進一步提升了適應性和消音性能。由電腦模擬可知,應用本文所提之方法於主動噪音控制系統上,可有效的消除相關與不相關噪音,並且有較好的適應性。

In practical active noise control applications, correlated noise and uncorrelated noise can be measured by error microphone. The weights update of the ANC controller will be affected when the error signal with uncorrelated noise into error microphone, reducing the performance of ANC. In order to improve performance of ANC, in this paper proposed a improved hybrid ANC structure and use an optimal variable step size to deal with the problem caused by the disturbance such that both correlated and uncorrelated noises that can be attenuate at the same time. Simulation results show that the proposed method can effectively eliminate correlated and uncorrelated
noise and improve ANC performance.
