Sound signal processing method and device, equipment and storage medium

The invention discloses a sound signal processing method and device, equipment and a storage medium. The sound signal processing method comprises the following steps: acquiring a sound signal through a configured sound sensor; performing short-time Fourier transform on the sound signal to generate a short-time amplitude spectrum; filtering the short-time amplitude spectrum through a filter to generate a spectrogram; inputting the spectrogram into a classification model obtained by training according to a convolutional neural network and a random forest model in advance, and outputting a classification result of the sound; and performing enhancement/weakening processing on the sound signal according to a classification result. Building a classification model according to the convolutional neural network and the random forest model; inputting the earth sound spectrogram obtained by the sound signal into a classification model obtained by pre-training, and outputting a sound classification result; according to t
