Aerodynamic noise is the dominant noise source of aircraft, generated by the interaction between high-speed rotating rotors and airflow. Early simulation at the conceptual design stage helps avoid vibration and noise issues and provides design guidance.

Perceptual indicators of aircraft NVH such as quietness, comfort and premium feel are broken down to individual components. NVH simulation engineers carry out multi-level simulation and optimization at full vehicle, system, subsystem and component levels.
