摘要
Abstract
This article discusses the method to analyze the acoustic contribution of body’s panels to vehicle’s interior noise.In the experiment, the vector sum of the product of sound-source intensity and acoustic transfer function is used to compose the sound pressure contribution of the panels.The source intensity of a panel is derived from the product of normal velocity of the surface and its area.Acoustic transfer function is measured via reciprocity principle.FEA calculation is done based on a model with the boundary condition and load condition of the foregoing experiment.Finally, test synthesized results, FEA results and measured data are compared one another.关键词
