As a result of the flow around a passenger car, different flat components are excited and, finally, sound is radiated into the passenger cabin. The physical mechanisms which cause this radiation of sound were investigated by using a simplified car model. For the analysis of the exciting wall-pressure fluctuations, a line-array of pressure sensors was used. The structural vibration of the side window was detected by means of a laser-scanning vibrometer. Finally, microphone measurements were performed in the interior. Due to the application of complex analysis techniques to the acquired measurement data, a description of the fluid-structure-acoustic coupling at a passenger car can be given.
