Wind Noise - A Practical Approach 640117

The principle cause of objectionable wind noise in the modern automobile is small air leaks in certain critical areas. The aerodynamic shape is insignificant in overall wind noise. The critical areas in order of importance are:
  1. 1.
    Vent window and door to “A” post sealing from the roof rail to about a foot below the beltline.
  2. 2.
    “C” post area at beltline.
  3. 3.
    Upper rear of front door area.
  4. 4.
    All other areas from roof rail to a foot below the beltline.
Conclusions reached after extensive testing show that wind noise can be eliminated by good sealing about the doors and windows.
