摘要: 
本論文將探討以獨立成分分析法為基礎之前饋式神經網路於主動噪音控制之應用。我們考慮一語音及一噪音訊號經空間路徑傳遞後,由兩支麥克風量測到混合之訊號,然後將量測到之混合訊號透過具MJH演算法之前饋式神經網路(FFNN_MJH),將語音及噪音訊號分離出來,並提供予主動噪音控制器,使其能輸出適當之控制訊號去激發喇叭,產生控制聲波來消除其中一支麥克風周圍之噪音,並保留語音訊號。由電腦模擬結果中顯示本系統對於單頻及倍頻之噪音訊號,在消除噪音及保留語音訊號上皆具有良好之效果,且在估測控制路徑不準確時本系統依然擁有適當之強健性。

In this study, an application of active noise control (ANC) using an independent component analysis-based feed-forward neural network (FFNN) is investigated. We consider a speech source and a noise source generating mixture signals in the space. Two microphones located at two distinct places are used to measure the mixture signals. Since the signal sources and the transmission paths are unknown, we apply a FFNN with MJH algorithm(FFNN_MJH)for the measured signals to obtain estimates of the signal sources. These estimates are then used for an ANC controller such that suitable control signal can be generated to drive a loudspeaker. It is desired that one of the microphone can observe the speech while ignoring the noise by use of the loudspeaker. Computer simulation shows that the observed microphone can effectively retain the speech while attenuating the noise with respective to tonal or harmonic noises. The proposed system also maintains a certain degree of robustness with respective to the uncertainty in the transmission paths of the loudspeaker, demonstrating its feasibility.
