A method for reducing NVH in a vehicle having the steps of providing at least one repeating event, replicating at least one component, and delaying at least one equivalent part. The repeating event is a complete cycle, such that the repeating event ends when the cycle begins to repeat itself. The component is replicated at least one time so that at least one equivalent part is formed. The equivalent part is delayed with respect to the component by angularly positioning the equivalent part with respect to the component in a predetermined way, such that at least one harmonic in the NVH-spectra is reduced during the component's repeating event and the equivalent part's repeating event in operation.
