Analysis of Vehicle Wind Noise in Wavenumber-Frequency Domain

Vehicle wind noise is an aero–vibro-acoustic coupling problem. Therefore, the wavenumber–frequency spectrum is useful to analyze flow field and vortex sound field with considering vibrations such as bending waves of a window glass. In this study, fluctuating surface pressure data on a window glass from CFD results are analyzed by the wavenumber–frequency spectrum method. Thus in this paper it is mentioned that analysis results of wind noise around a vehicle body which are caused by exterior parts to estimate input power for vibro-acoustic simulations.
