Well site noise characteristic spectrum database generation method and device, electronic equipment and medium

The invention relates to a well site noise characteristic spectrum database generation method and device, electronic equipment and a computer readable medium. The method comprises the following steps: performing empirical Fourier decomposition on well site noise to be analyzed to generate a plurality of noise signals; calculating a plurality of polynomial transformation values of the plurality of noise signals based on a polynomial transformation formula; generating a plurality of instantaneous frequencies of the plurality of noise signals based on the plurality of polynomial transform values; generating a plurality of generalized synchronous extrusion polynomial transform values of the plurality of noise signals based on the plurality of instantaneous frequencies; calculating characteristic indexes of the plurality of noise signals based on the plurality of generalized synchronous extrusion polynomial transformation values; and generating a noise characteristic spectrum library based on the characteristic in
