Abstract：To mitigate the operational noise of range hoods,it introduces an active noise control(ANC)method using multi-channel data fusion.This approach fuses signals from multiple reference sensors into a single input,creating a computationally efficient Single-Input Multiple-Output(SIMO)control system.This method not only maintains noise reduction performance but also enhances robustness against hardware variations.Experimental results show that,compared to a conventional MIMO system,our proposed method achieves equivalent noise reduction at the listener's position with a 75％decrease in computational load.The technology has been successfully validated in commercial range hoods,proving its practical value for engineering applications..
