The Effect of Body Shapes on Wind Noise 780266

In order to reduce wind noise, it is important to minimize the intensity of the noise source itself as well as to insulate the noise. The effect of body shapes on wind noise was investigated. The results are as follows:
  1. (1)
    Concerning wind noise, one of the fundamental causes is flow separation. The most critical areas are the windshield and the A-pillar.
  2. (2)
    A certain relationship between rain gutter height and side window recess depth produces the most wind noise.
  3. (3)
    Wind noise is suppressed if the airflow velocity is reduced around the A-pillar by an object such as the wind deflector.
