Wind Noise

mrsoft

Any tips on how to reduce wind noise on a car. Have a 2010 Grand Picasso and its driving me nuts (no pun intended).

Cheers.

Yea thanks. Extremely helpful.

More information. What sort of noise is it - is actually wind noise, or is it more like tyre noise? At what speed does it become problematic? Has the car a sun-roof or one of these "Panorama" jobs? I suppose the windows are closed?? :pac:

Silicon spray on the door seals.

It's how Volvo cure the wind noise problems on the V50/S40.

Its a wind noise and its kinda there the whole time. Obviously worse with speed and on windier day.

When you say spray silicon do you mean directly on to the seals or do I remove them and spray underneath?

Onto the seals.

It also prevents them freezing together in the winter.

Another option is to adjust the door striker plate inwards. Usually secured by 2 Torx bolts. Loosen off a turn or two, DO NOT REMOVE, push inward 1mm or so and tighten. Very easy to do.

This will tighten the door to the frame when closed and may result in a better seal.

Mr.David

You have to figure out the source of the noise and whether it is due to poor sealing or just the form of the vehicle in order to decide on how to improve it. It could be due to anything really.

Strip it, apply noise cancelling foam/paint. In my car that would be the only solution.
Look around citroen forum, maybe that's just how this car is build. But like previous poster said that can be anything. From something small to something big.

Noise canceling paint?

Is there wind deflected on the car if so burn them! Taking them off just ist enough!! Missus put a set on the jetta. Serious noise after.

I dont remeber the name now but on Mazda forum there was a guy who did use paint/foam to reduce the noise.
EDIT:
Here are some photos.
He used this.

Im more than happy to live with the trade off of the noise of wind deflectors if it means I can open my windows in the rain!

That hardly applies to the thread though.

For the OP.

To deal with wind noise, the best thing you can do is check your door seals and sunroof if you have one. With the car parked, have the window open and close the door with a sheet of paper laid on the seal and check how much resistance you have when you pull it out. Best to use thin strips so you can test each part of it. If there is any noticeable lack of resistance, you know the weak spot of the door seal.

My car has a main door seal then some secondary ones which run along the roof line. I filled the secondary one with silicone so it cant deform when the door closes. I have also filled the primary seals with clothes line for the same reason.

For road noise, taking out each interior panel will be required. Then, using strips of rubber and liberal amounts of glue, you can add mass to the panels which will lower their resonant frequency and dampen their mid to high frequency tendencies. For anywhere you cant get rubber strips glued on, a thick sound deadening paint of some sort would be a good compromise.

Do this to all panels you can. For me, it was the door skins and most of the boot but I have not had the money or time to go through the car fully. You can also take the plastic cowling around the wheel arches off and paint the body shell which is revealed - I would not trust gluing rubber onto those. Though, as it is exterior, you could get away with using a very thick paint if the sound deadening paint is hard to get or not as gloopy - I am thinking tar line substances, but I have no products in mind.

On my car, I managed to take away a lot of cruise speed road noise using the above rubber and glue technique, so much so that the resonant frequency of the car was moved enough that you can notice the car being slightly louder at very low frequencies than it was at very specific low speeds.

I got rid of so much road noise that amount of wind noise I have to deal with is revealed which is a pain as there was a lot of effort gone into getting rid of road noise.

I got some new seal for my drivers door from sealsdirect in the uk. They fit fine but I couldn't get the plastic trim to fit flush so I just stuck on the old trim. I have wind deflector so that could be causing some of the wind noise. I must pick up a can of silicone spray and see if it improves the seal.

Re the post above. To find out where the wind noise is coming from turn on you're fan to max and listen or hold a sheet of paper near to glass. Even a lit cig etc should show where the weak spot on the seal is.

Sometimes it's the wing mirrors. Try driving with them folded in and see if this helps.
If it does there are yokes you can put on the mirror to "break up" the wind a get less noise that way.
This is usually for more of a whistling noise but hey.

Phew. Really appreciate the replies here. Gonna work on some of those tomorrow evening.

I'll report back with updates.

Btw I dont have a sun roof. Im on my second picasso and other one had no issues with wind noise.
