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..
