As the most metaphysical area of NVH in automotive technology, there is a saying that “there is no best, only worse and worse.” It seems that the NVH level of a car is not perfect, only infinitely close to perfect. Symphony of the many voices N (Noise) V (Vibration) H (Harshness) Presumably we all know, but for the last H, it is necessary to say a few words. Harshness is the meaning of acoustic vibration roughness, referring to the quality of noise and vibration, is to describe the body’s subjective feeling of vibration and noise.
