Sound power determination method and device, computer equipment and storage medium

The invention discloses a sound power determination method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining the volume velocity of an equivalent sound source corresponding to an excitation source, and enabling the volume velocity of the equivalent sound source to be obtained after the excitation source is tested based on a whole vehicle test environment; and based on the volume velocity of the equivalent sound source, a pre-constructed sound radiation model of the excitation source is simulated to obtain sound power of the excitation source in a free sound field, and the sound radiation model represents a sound radiation model of radiation from the surface of the excitation source to the free sound field. By means of the means, the problems that in a traditional scheme, it is difficult to establish a rack testing environment and it is difficult to control rack working parameters to be consistent with whole vehicle parameters are solved, and the testing univers
