In this paper an approach to a holistic interior noise prediction is presented. It makes use of contributions derived from simulation and experiments and therewith provides the engineering freedom to evaluate the total interior noise under customer oriented driving conditions even during early project phases when hardware is not available. With respect to wind noise, contributions from the greenhouse are predicted by coupling of an unsteady Computational Fluid Dynamics solver to a Statistical Energy Analysis solver. The paper presents a validation of this approach for various configurations that impact wind noise by comparing simulation results to wind tunnel experiments. The predictions are used to evaluate the effect of those configurations on the total interior noise levels for different generic vehicle setups at constant highway velocities.
