Active noise reduction method and device for range hood, electronic equipment and storage medium

The invention provides an active noise reduction method and device for a range hood, electronic equipment and a storage medium, the method is applied to a controller of the range hood, and the method comprises the following steps: acquiring a vibration acceleration signal of a motor; determining a motor rotating speed corresponding to the acceleration signal based on a rotating speed calculation model; determining a noise phase corresponding to the motor rotating speed based on a noise phase prediction model; and determining an anti-phase sound signal corresponding to the noise phase based on the secondary sound digital model, and performing active noise reduction based on the anti-phase sound signal. In the mode, the vibration acceleration signal can be used as a reference, and the anti-phase sound signal is regulated and generated to perform active noise reduction. Compared with a noise signal as a reference, the method can reduce the interference of environmental noise, and improves the secondary sound acc
