Abstract
Noise evaluation method based on sound power under laboratory conditions and the noise evaluation index system including the sound power per volume, sound power per mass, sound power per power and equivalent sound power were established. Through analyzing the noise characteristics of electric vehicle drive motor. The test of enhanced magnetism DC drive motor and AC drive motor based on sound intensity method of sound power were evaluated, and the result proved that the established evaluation index system and evaluation method in the evaluation of content were rationality, according to the calculated parameters combined with the actual scene perception.
