Substation active noise reduction method and device combined with sound image recognition, equipment and medium

The invention belongs to the technical field of noise reduction control, and particularly relates to a transformer substation active noise reduction method and device combined with sound image recognition, equipment and a medium. The method comprises the following steps: carrying out gridding division on an overall noise distribution diagram to obtain a first noise distribution diagram; performing meshing division on the first noise distribution diagram to obtain a second noise distribution diagram; determining noise sound pressure in each second noise distribution diagram; determining a position relationship between each second noise distribution diagram and the loudspeaker, and determining a weighting coefficient of each second noise distribution diagram according to the position relationship; according to the noise sound pressure in each second noise distribution diagram and the corresponding weighting coefficient, the single sound pressure level of each silencing subunit is determined, according to the sc
