A simulation model has been developed for the prediction of road-excited noise under steady-state conditions. It considers the flexibility of the vehicle structure and uses measured input mobility and modal mobility data or noise transfer functions measured at suspension input points to compute the sound pressure level inside the vehicle. Theoretically determined structural data from Finite Element analysis may also be used. This paper presents results from a test vehicle and indicates how this model may be used in conjunction with a vehicle ride model to choose vehicle suspension and tyre parameters for optimum refinement of the vehicle.
