A Sound Simulation Technique Used for the Prediction of Passenger Compartment Noise

A sound simulation technique has recently been developed that allows the NVH engineer to subjectively and objectively predict the passenger compartment noise levels due to radiated transmission gear noise. By using the simulation technique, a noise evaluation can be performed in the early stages of vehicle development, allowing NVH analysts and design engineers to address potential noise concerns well before production of the vehicle is scheduled to begin.
