In order to predict interior noise of automobiles, aeroacoustics simulation was carried out. Generally, flow fields are calculated in the time domain. Therefore, acoustic analysis of interior noise caused by aerodynamic noise and force should also be solved in time domain. CIP method is suitable for time domain wave equation analysis. In this investigation, we attempted to apply the CIP method to calculate the Lighthill equation. The simulation results showed this method is possible to calculate accurately the aerodynamic noise. Moreover, the results showed that the contribution of aerodynamic sound around a car body to the interior car noise is larger than that of the hydrodynamic pressure fluctuation of vehicle surface.
