Thread: Road noise and air seal question.

    Road noise and air seal question.

    Hey all, so all the cars i have worked on have had an air pressure vent in the back left or right corner of the car. Its there so that the air pressure equalizes when you close your door and the seals don't pop from being pressurized.

    The issue being, they are generally fairly large and are always made from super thin plastic. They let SO much road noise in. I have a couple ideas on how to address the issue but im curious what all you have done on your vehicles to fix the issue

    Re: Road noise and air seal question.

    When my truck seats are in, I can't hear the road noise from them. When the seats are out I could. I left them as they are the least of my road noise concerns and have a very valuable job to do (not just for opening and closing doors but also allow your AC/Heat unit to function properly). I guess you could cover them with an aperiodic membrane or something, that still allows air to flow out but could block some sound limited amount of sound.

    Sometimes in my car at about 80 it practically sounds like the window isn't up all the way! I'd love to quiet that down some how. Please share your ideas.
