The vehicle cabin is not a strictly rigid body and as a consequence it will slightly expand when under high inside pressure which lead to a smaller natural frequency and will also absorb energy resulting in a damping loss and thus lower buffeting SPL.
The interior trim of the cabin absorbs energy resulting in a damping loss and thus lower buffeting SPL
This flow area is seen to act as the main source for the buffeting [9].
It should be noted that there is an obvious difference in the range from 50 to 70 Hz, but this is not of further concern since the main objective is the accurate prediction of the buffeting effect with its peak SPL and frequency.
