The invention relates to a filter coefficient determination method and device based on a transfer function and electronic equipment, and particularly relates to the technical field of audio processing. Comprising the following steps: under the condition that an audio listening scene corresponding to a first loudspeaker in a physical space is determined to be a target listening scene, acquiring a target transfer function correspondingly set by the first loudspeaker in the target listening scene; wherein the target listening scene is one of multiple listening scenes, and the expected propagation paths of the first loudspeaker in different listening scenes are different; performing distortion processing on the audio signal to be detected according to the target transfer function to obtain a distorted audio signal, the prediction filter being a filter corresponding to the first loudspeaker; acquiring a predicted audio signal output by the prediction filter based on the distorted audio signal; calculating a mean s
