Although the rear side window buffeting has the same generation mechanism of the sunroof buffeting, few feasible measures have not been suggested yet because of the restrictions by the aspect of styling and vehicle structure. The former research on this topic said that measures to control the buffeting strength can be cascaded in three categories; Aerodynamic force control, buffeting frequency control and Q-factor control, and revealed that the buffeting frequency control is the most practical measure. This study is likely to describe the concrete measure to change the buffeting frequency and will show parameters that should be considered at the design stage. This study also shows that the rear window opening aperture has a strong relationship with the buffeting strength and its frequency through the multivariable analysis. Based on the results of this study, design guides to reduce the rear window buffeting according to door types are suggested..
