The embodiment of the invention discloses a generator noise control method and device. The method comprises the steps of determining a high-noise rotating speed interval of a generator according to anoise characteristic curve of the generator; in the operation process of the generator, receiving a rotating speed signal of a generator, judging whether the rotating speed signal of the generator isin the high-noise rotating speed interval or not; and under the condition that the rotating speed signal of the generator is judged to be in the high-noise rotating speed interval, changing the rotating speed signal of the generator by setting and changing the target rotating speed of an engine so as to enable the rotating speed signal of the generator to be separated from the high-noise rotatingspeed interval and reduce the noise generated by the generator. According to the generator noise control method provided by the embodiment of the invention, the working point of the generator is controlled to avoid the high-noise interval by adopting a rotating speed closed-loop control method, so that the purpose of reducing the noise of the generator is achieved, the NVH performance of the wholevehicle can be improved on the premise of not increasing the cost of the generator and the cost of the whole vehicle system, and the satisfaction degree of users is improved.
