In this guide, you’re going to learn different ways on how to reduce wind noise in the car. As we highlighted in the previous article, wind noise is one of the most causes of a noisy ride.
Less aerodynamically designed cars, such as SUVs, are most prone to wind noise. Other factors also determine how noisy or quiet your car is. Let’s see different ways on how to make your car quieter/ reduce wind noise in the car.
What Causes Wind Noise in Car?
Wind noise is a common problem, especially in all vehicles, since they experience wind resistance when moving. Understanding the causes of the wind noise into your car will help you reduce the amount of sound reaching you when driving.
Some of the causes include;
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 prone to wind noise. This is known as aerodynamics.
A sports car is an example of vehicles with better aerodynamics. They produce less noise compared to larger vehicles like trucks, which create a lot of wind noise when moving. The large vehicles have disturbances when moving.
Whenever a car is moving, it is pushing air, which leads to pressure change. The air in your car will have higher pressure and starts finding a way to escape outside where the air is under low pressure.
This will create sounds of wind when driving. Openings in your car allow the air to flow outside to stabilize the pressure in your car. They are situated in places away from the people inside the car to ensure that the noise does not disturb them.
The openings are designed to produce less noise when air is escaping. When the air escapes through other ways, it will produce more noise.
How to Reduce Wind Noise in Car
1. Locating the Source
identifying the source of the noise is the first step in reducing wind noise. You can identify the problem by driving in a quiet place while listening to your car. Ensure there is no music playing during this time so that you will be able to hear the noise better
You can also carry some passengers to help you identify the source of the noise. Make sure you pay close attention to the doors, windows, and the exterior car body. The seals and weather stripping on your doors and windows may be worn out, resulting in the wind noise.
Once you identify the root cause, try to inspect your car properly to check if there is any deformity on the part the noise is coming from.
2. Inspect the Car Doors
Since the doors are the largest entries in your car, you should frequently check if they are in good condition. A damaged door can leave some space after closing, which can turn out to be an opening where airflow inside the car.
If you notice that there are some deformities on the doors, take the car to a professional if you don’t have the skills to fix the problem. Don’t try fixing it yourself if the problem is complex to avoid further damages to your car.
3. Replace Car Door Seals that are Worn Out
Car doors have seals and weather stripping that may wear out after some time. Worn out seals have some holes or gaps on them, which may be a way for air to escape.
The seal may be okay but has fallen from its position, giving way for air to escape. Fixing the seal is easy, and you don’t have to call a professional to do it for you. Use weatherstrip adhesive to reseal it to the frame.
Apply the automotive adhesive directly to the seal the press into the door frame. The adhesive comes in many different colors so you can choose your preference. Amazing GOOP II Max or 3M Super Weatherstrip Adhesive are great automotive adhesives that work perfectly.
This also applies to weather stripping on the door frame and the car door window. If the seal is worn out, you will have to purchase a new one, which you can fix it on your own.
What you have to do is remove the old seal, then clean the area to remove the previous adhesive. Install the Great BBA Large D-Shaped Rubber Car Door Seal on to the surface you have just cleaned. The best part is that the door seal has an adhesive backing and you don’t need to use an automotive adhesive.
4. Inspect the Exterior Car Body
If, after inspecting the doors and windows, you have found that they are all okay, try checking the outside body of your car. Check whether the body has rust or damage from an accident, holes, or cracks in the window shields.
A tiny crack may provide enough space for air to escape through producing wind noise. Consider taking your car to a professional to replace the car windows if there are have cracks on the glasses.
If there are holes or rust, seek professional repair or try filling the holes with a patching kit. Seals on the permanently closed windows may be worn out. If that the case, buy Dynatron 550 Auto Seam Sealer Grey Caulk to replace them. The sealer can also be used in door window seals or door strips.
Installation of wind deflectors is one of the cheapest ways of reducing wind noise. They are made of plastic and cover the top of the window to minimize the wind reaching the area where the weather stripping is attached to the window.
There are different wind deflectors specially designed for specific cars, so be keen when purchasing one for your vehicle. There are deflectors for every modern car, so you will find one that suits your car.
The installation easy and only takes a few minutes. What you have to do is peel the adhesive backing then from outside, insert the lip on top of the window frame. Push the lip up the frame and exert pressure for the adhesive to stick.
