With the development of automotive wind tunnel technology and the increase in the number of automotive wind tunnels,wind noise testing in automotive wind tunnels has gradually become the main testing method for automotive wind noise development.The article is based on wind noise testing in automotive wind tunnels and investigates the influence of measurement point positions on test results.Study is found that when the position of the artificial head inside the car changes in the X direction,the total sound pressure level,articulation index,and loudness change slightly,but there are differences in the spectral characteristic curves.The sound pressure level and loudness all show a increasing trend with increasing height in the Z direction,and articulation index show a decreasing trend.The farther the far-field microphone outside the automotive is from the center of the force balance in the Y direction,the lower the sound pressure level will be.
