Method and system for predicting sound pressure levels within a vehicle due to wind noise

摘要

A programmable digital computer system is utilized for predicting sound pressure levels (SPLs) within a vehicle due to wind noise by utilizing data representing pressure spectra for vortex, reattached and turbulent boundary layer flows over a glass side window of the vehicle. The method and system preferably utilize data representing physical properties of at least one door seal of the vehicle. A set of pressure coefficients is determined so that a vortex area in turn can be determined and utilized during computation of the SPLs. Plots of the SPLs over a predetermined frequency range can be displayed for a driver's ear position as well as for a passenger's ear position within the vehicle.
