The invention relates to the technical field of noise optimization, and discloses a starting noise optimization method, device and equipment and a storage medium, and the method comprises the steps: carrying out the noise test of a vehicle under different starting conditions, and obtaining a noise test result; performing noise separation on the noise test result to obtain a rotating speed range and a torque range in which the noise of the motor does not conform to the specification under different starting working conditions; and starting noise optimization is carried out based on the condition that the motor noise does not conform to the specified rotating speed range and torque range. According to the method, starting noise optimization is carried out through the rotating speed range and the torque range, which are obtained by carrying out noise separation on the noise test result and are not consistent with the specified motor noise under different starting working conditions, so that the problems that the whole vehicle cost needs to be additionally increased and complete optimization cannot be carried out in current starting noise optimization are solved; the optimization effect and the optimization efficiency are improved, and the cost is saved.
