Unbearable Wind Resonance > 60kph/40mph

[Altitude]

I have them on my LB and yes they do work to minimize or eliminate the wind buffering.

I've done the same thing... more than once.

It's most obvious for me when either one of the rear windows are wide open and all others shut, driving at above 60kph/40mph. I've done some confirmation tests like driving at that constant speed, open one rear window until my ears can't handle, open one front window and the thumping noise is gone. Is it a coincidence of the cavity design that causes this? Maybe it's time I look into a spoiler INSIDE my car.

Dude.... all cars have horrible wind resonance when driving 60+mph with one window open. It's physics, you aren't going to get around it in this world.

Car going fast creates a spot of low pressure, open the window, and now you created low pressure at that window. High pressure air from outside the car is literally pushed into the window.

I suspect there is a point at which the high pressure blows into the car so much that it creates an imbalance in the opposite way and the pendulum then has to swing back (hi-pressure in car now, air blows back out)... and this goes back and forth fairly quickly thus causing a similar sensation to hearing an amazing subwoofer setup playing 5-10hz tones. You feel pressure on your ears, but don't really hear the sound (yes, there is some sound, but you don't hear the 5-10hz tones).

I haven't dug far enough into my sedan to find out if there are slam valves in there anywhere; if I find them, I will wedge them wide open, should help. Meantime, I manage the row with window adjustment, which is of no value to 3-door drivers.

Ideally, I would put vents into the rear pillars: not only would that help the wind noise, but it would add a LOT to the efficiency of the heat/vent system. I can't believe that Toyota didn't use that old cure, my buddy's Cortina had those vents, and the heat/vent system was second to none!
