As the growing popularity of hybrid and electric powertrains leads to lower cabin noise levels, and often more complex drivelines, attention focuses on improving drivetrain refinement by reducing noise, vibration and harshness (NVH). Some companies are already ahead of the curve, using sophisticated NVH test techniques to ensure that the required refinement levels are maintained throughout the entire production run of assemblies such as axles, differentials and transfer boxes. One such company is Dana UK Axle.

Automotive powertrain systems are inherent generators of tonal noise. Whenever gears, sprockets/chains, fluids or electricity are used to transmit power, some degree of tonal noise is inevitable. If such tonal noise stands-out above the general level of background noise in a vehicle, it is considered by many to be annoying.
