Noise Vibration and Harshness (NVH) gain importance in powertrain development. Emerging fast and predictive simulation solutions together with high-resolution measurement methods provide extended insight into the governing excitations and noise transfer paths.  Creating the synergy between cutting-edge noise simulation and measurement methods and corresponding performance-oriented toolchains allows accounting for NVH limits in the engine calibration process.  Demonstrating the advantage of this new paradigm in reducing powertrain development time forms the premise of this WP.
