本文在风洞实验的基础上，提出了气流噪声向汽车内部传播的理论模型．采用边界元法，研究了车外脉动压力透过板壁和气流噪声通过孔隙向车内传播以及相互之间的耦合关系．给出由外部脉动压力和气流噪声计算车内声场的计算公式．
Based on the wind tunnel experiment, this paper presents a theoretical model of airflow noise propagating into the vehicle interior. The boundary element method is used to study the coupling of the pulsating pressure outside the vehicle to the vehicle through the wall and the airflow noise through the aperture. The formula for calculating the sound field in the vehicle from external pulsating pressure and airflow noise is given.
