Very difficult to assess in home environment on computer speakers, but yes the lower frequencies seem to be much louder. 95Db would be like having a rock band playing in the car!!
However i've been out this morning and can give you the following figures
Mk3 CVT Tyres Dunlop 2030, Aircon On, fan running on 3rd notch. Location M42
Sound meter lying on front passenger seat & set to fast response Dba Scale
In car stationary engine ticking over:- 46-48 Dba
At 30 MPH 56-58 Dba
At 50 MPH 60-62 Dba
At 60 MPH 62-64 Dba
At 70 MPH 68-70 Dba
It's apparent that the major source of noise is road/tyre noise, where when coming back home over some local roads, the 30MPH result could be significantly higher.
Conversely, increasing the speed makes little difference.
The noise from car itself appears insignificant.
So I guess there is something definitely wrong with your car which needs looking at.
Can you hold a conversation in the car without raising your voice?
Hope this helps
