Whether you’re driving an electric-powered, hybrid-powered, or diesel-powered vehicle, they all have a powertrain. The engineering landscape for powertrain NVH engineers has changed significantly. Fuel efficiency measures to reduce emissions inevitably impact the vehicle’s NVH and acoustic behavior. Weight reduction and downsized turbocharged engines might cause low-frequency driveline NVH issues when integrating the driveline into the vehicle, while novel energy management systems can cause transient NVH phenomena. These new complex NVH issues need to be addressed on top of the typical engine-related NVH topics, such as; engine radiation, gearbox rattle, whine, judder, clunk, fuel slosh, intake and exhaust noise, and auxiliary noises.
