While driving on the highway have you ever felt that your door is partially open because of the wind noise you hear? You’re not the one who faces this problem alone and is annoyed with the wind noise in the car cabin.
When driving and expecting some peace and joy the wind noise passes through and takes over the joy and you can’t even talk to the person sitting next to you or else you have to shout and talk because of the loud wind noise in the car.
Wind noise is one of the most common problems when it comes to excessive noise in car cabins. If your vehicle is allowing more and more creep noise over the years then you may actually be right. If the noise passing through the wind in the vehicle is loud then you need to consider some of the solutions to reduce this noise in the car.
If you’re looking for how to reduce wind noise in a car then you have landed in the right place. In this guide, I will walk you through some of the ways to reduce wind noise in a car that will make your car quiet.
What Causes The Wind Noise?
All vehicles have some degrees of wind noise when you’re driving at a certain speed then you will be experiencing some serious wind resistance but there is no way to completely avoid the problem all you can do is understand the root causes of this problem and take some preventive measures.
Here are some of the components of vehicle wind noise that will cause wind noise in a car. let’s discuss some of the components.
Air Pressure
When the car is moving it is pushing air which will lead to pressure change and the air in your car will be having higher pressure and it will start to find a way to escape outside where the air is under low pressure.
This will create wind noise while driving. The opening in your car allows the air to flow outside to stabilize the pressure in the car. They are situated in places away from people inside the car to make sure that the noise does not disturb them.
The openings in the car are designed to produce less noise when the air is escaping. When the air escapes through other ways it will produce more noise. This is the most common cause of the wind noise your experience in a car.
Aerodynamics
Some vehicles are designed in such a way that they will face less resistance when cutting through the air than others. Such cars are less likely to wind noise than others this is called aerodynamics.
A vehicle with better aerodynamics is less likely to produce much wind noise the best example of this is a sports car that produces less wind noise than the other big cars like trucks and SUVs they are creating a greater disturbance in the air pressure moving.
The larger and boxed vehicles produce more wind noise in a car than the sports car which is differentiation and they are a better example of aerodynamics.
Seals
Seals are the real culprit in passing the wind noise in a car. since doors and windows are the largest holes in the vehicle. As the air in the car cabin tries to get out and it goes through specially designed discharge vents in the car. the air doesn’t know the path to get out hence it will take the less resistant path.
The doors are sealed with the weather stripping to create an effective seal against the air escaping. The seal will get smashed and flattened and eventually it can be crushed to be effective beyond this it can also be subject to some other damage such as dry rots, rips, and tears.
However, any damage to the door seals can render them ineffective the same applies to the window seals. When you roll up you’re window it will be sealed with the weather stripping around the glass on the top.
If the weather stripping gets damaged due to the sun and it gets cracked or broken then the results will be similar air from inside of the vehicle uses the space to escape creating loads of wind noise.
How To Reduce Wind Noise In A Car
Here are some of the ways to reduce the wind noise in a car that will help you to make your car soundproof from the wind. Let’s dive into the ways to reduce wind noise in a car.
1. Locating The Cause
Before we solve the wind noise in the car we must first find out where the noise is coming from. As we have already established the air in the cabin is going to look for the path of the least resistant which could be anywhere.
The first thing you can do is simply drive down the road and listen. Make sure to keep the cabin quiet so that you can hear the noise clearly and try to pinpoint which part of the vehicle is producing that noise.
The next thing you can do is get some passengers in your car and drive with the cabin quiet passengers so that each passenger can listen around their vehicle for anywhere the noise is more concentrated. Make sure the passengers pay close attention to the roof, door, window all the corners of the cabin.
Make note of the noise anywhere is discovered so you can do a deeper inspection of the area.
2. Replace The Door Weatherstripping
Weatherstrip seals on your doors and windows against the air escaping are some of the most likely causes of air leaks that create wind noise. If you have determined from step one the location any noise then you can start there when inspecting the weather stripping.
Open each window and door and inspect the seals all around. Look for any type of damage at all such as being crushed, ripped and torn, or no longer attached. Make sure to check all around the trunk and roof as well.
When you identify the damage then it’s time for repair and if the weatherstrip is unattached then you can use some weatherstrip adhesive to re-attach the weatherstrip.
If you find the areas of the weather stripping are crushed and maybe too flat to seal properly then you have two options the first option is to try rubbing some lithium grease into them to expand back to their full size and if that fails you can replace them with the car weather stripping.

3. Check The Doors
So after checking with the weather stripping and everything seems to be fine but what about the door themselves? Sometimes damage to the door can either stop it from closing all the way or create space where air can make its way into the vehicle.
You can start looking for the signs of the major dents and if you find such dents then you need to take your vehicle to the professional because you cannot repair the major dents by yourself.
After checking for the major dents open and close each door make sure that the latches shut completely with no obstruction and if your door does have an issue latching all the way shut you may need to inspect the latch on the door.
If there is something obvious then you can some cleaner or metal file and fix it yourself and if you find more than minor issues then you need to take help from a professional.
4. Install Sound Deadening Mats
Sound deadening mats are one of the best solutions to mitigate any type of noise in your car. These thick mats absorb the sound and vibration helping to drastically reduce the transmission of noise in any vehicle.
Sound deadening mats are used on the floor, doors, and trunk of the vehicle to help reduce vibration and excess noise in the entire car. To install the sound deadening mats you need a bare metal floor and place the around deadening mat on the floor.
For doors, you need to take out the door panels and place the sound deadening mats, and pit back the panels. However for a soundproofing trunk then you need to take out everything and place the sound deadening mat on the trunk.
While this is very time-consuming at the same time it’s a very effective method for reducing all sorts of excess wind noise in the car. for a more detailed guide check out sound deadening car doors.

5. Clean The Door Drain Holes
The doors on your vehicle feature little weep holes that allow water to drain this takes place when your car is wet say at a car wash or in a rainstorm then the water makes its way into your doors by squeezing down through the weather stripping at the bottom of your window.
Dirt can cause these holes to fill up which then stops the water from draining. But when they are clogged they create another problem without the proper air circulation they allow the air will search for a different way out of the vehicle which will most likely be noisy.
This is very simple and can be fixed quickly. All you need to do is just simply open the door and locate the little holes on the bottom or side of the door. Use something small and hard such as a paper clip simply empty the hole so that airflow can continue in the vehicle.
6. Use Sound Deadening Spray
The undercarriage of your car is a place where a lot of noise makes its way back into the cabin. All the noise of the vehicle is reflected back by the road. One of the effects to reduce the wind noise in a car is applying sound deadening spray undercoating on your car undercarriage.
The sound deadening spray is a soundproofing spray that can apply in several coats to reduce the transmission of the noise. it absorbs sound and dampens the vibrations passing in the car cabin as well provides a protective layer against the chips and cracks in a car.
The process of applying is simple and you can do it yourself all you need to do is take out the things from the car and clean it thoroughly and start applying the spray on the car cabin and it can be applied on several parts of the car.
There are several types of sound deadening spray on the market and all of them are very effective and give good results but I would recommend DEI sound deadening boom mat spray

7. Install Acoustic Windshield
The windshield is constantly pushed by the air as it is in front and it makes sense that the windshield is taking the load of the wind and it’s making offending wind noise as the air is pushing the windshield makes it the major cause of wind noise in a car.
Replacing the existing windshield with an acoustic windshield will reduce the wind noise in a car and it will quiet the cabin. On the other hand, an acoustic windshield also provides other benefits like protection from UV rays and direct sunlight.
They provide a more comfortable ride and protection against the UV rays which will protect the interior of the car from fading. If you like to learn more check out our guide on acoustic windshields.
8. Install Wind Deflectors
Installing wind deflectors on your vehicle is one of the cheapest and easiest ways to drastically reduce the wind noise in a car. it’s a plastic piece that will cover the top of your window and prevents the wind from hitting the area where the window meets the weather stripping.
Wind deflectors are vehicle specific so make sure you get the right one for your vehicle they are available for moderns car so you will not face problems in getting the one for your vehicle.
Wind deflectors can be installed easily all you need to do is just peel off the adhesive backing and insert the tip into the top of the window frame from the outside push the lip up into the window frame and provide enough pressure so that the adhesive can stick properly.

Final Thoughts On Reducing Wind Noise In A Car
No matter what soundproofing method you choose any method will have a powerful effect and the results will be more effective you can notice the difference in the wind noise in a car before applying the soundproof method to reduce wind noise in a car.
For more effective results use two methods at the same time and apply them at the same point in time the effective results and to avoid the hassle of installing separately. Try sound deadening mats for the reach to reach places also sound deadening spray is one of the better choices for hard to reach places.
Even if your choose one method that will be effective and cut down the wind noise few percent will make your ride smoother and quieter.
