Noise Vibration and Harshness Control, NVH

Consumer preferences must be considered when designing for sound and vibration damping and noise frequency harshness. Consumers can be sensitive to high-pitched frequencies, so even the smallest squeaks and rattles can greatly affect product satisfaction. At the same time, consumers tend to associate lower frequency sounds with higher quality - as when a vehicle door closes with a reassuring thunk. Vibration can be an urgent concern as well.
