    Abstract: To overcome the weakness of the existing noise evaluation method for the window lift motor, a kind of abnormal noise evaluation method based on objective psycho acoustic metrics is proposed. As the existing objective psycho acoustic metrics cannot be fully applicable to the window lift motor noise evaluation, based on the sharpness of the Zwicker m... Show More
