Wind noise Fiat Ducato van

[Vanterrier]

Door seals and alignment. If they are not a close fit you will get excessive wind noise
If you have aerials, rooflights, solar panels and air vents on your roof you will not be able to avoid wind noise especially at those speeds... 56 mph+

There is a vent at the bottom of the A pillars too, stuff some sponge cake in them.
