Audio noise reduction method and device, electronic equipment and storage medium

The invention discloses an audio noise reduction method and device, electronic equipment and a storage medium, and relates to the technical field of audio processing. The method comprises the following steps: obtaining the sensitive volume of an audio to be processed under a preset frequency band, wherein the sensitive volume represents the critical volume at which a user can hear the sound; obtaining the noise volume of the audio noise under the preset frequency band; obtaining a personalized benefit reduction factor based on the sensitive volume and the noise volume, wherein the personalized benefit reduction factor is used for weakening the audio noise of the to-be-processed audio; determining a target frequency spectrum after noise reduction based on the personalized benefit reduction factor; and obtaining a target audio based on the target spectrum. According to the method, adaptive noise reduction is carried out on the audio according to the sensitivity degree of the user to the sound, so that the noise
