Abstract
Self-excited sound caused by flow is observed in the vehicle cabin, when the vehicle runs with an open window. This phenomenon is called wind-throb. In this study, we measure the sound pressure in the vehicle cabin and explore the possibility of suppression of self-excited sound generated by Fluid Resonant Oscillation. We tried to prevention of wind-throb by using of a baffle plate. A baffle plate is set inside of the cabin. Accordingly, in this study the baffle plate prevents from occurring wind-throb.
