While a car is moving, there will be different perceptions of the noise in the car between the driver and a person sitting next to him. In this case, the driver must be more focused so the perception of the noise will not be as good as other people’s. Why is there noise in the car and where does that noise come from?
As you know, anything that attaches a machine will create noises, so with a car, the noise is of course caused by the operating machine. When you turn on the air conditioner, the sound will increase because there is more air conditioner operation such as the noise of the air conditioner fan.
And if your car is poorly soundproofed, the noise will come from the road surface and the wind blowing into the car also causes sound. Those are the main causes of the noise phenomenon. To reduce the noise, you will have to get rid of or at least weaken those causes. In this article I will give a few ways to reduce the wind noise in the car. Hope they will be useful to you.
Now together we will find out some causes of the wind noise in a car
What Causes Wind Noise in Cars?
All vehicles are going to have some degree of audible wind noise. When you’re hurtling along at 65+ MPH, you’re going to be experiencing some serious wind resistance, so there’s no way to completely avoid the problem. However, by understanding the root causes of wind noise making it into the cabin, we can take preventative measures.
There are three main components of vehicle wind noise. Air pressure, aerodynamics, and your car’s seals.
As your vehicle propels down the road, it’s pushing the air and creating changes in pressure. The air moving rapidly outside your vehicle now has lower pressure than the air inside your car’s cabin. The higher pressure air in your car then tries to find a way to escape to the lower pressure area outside. This is what creates the sound of wind around your door openings as you drive down the freeway.
Vents inside of your vehicle allow this air to escape to maintain proper pressure in the cabin. These vents are pointed away from passengers and situated so as to make the least noise possible while allowing the air to escape.
Since they are designed to be quieter, these vents are the only place you want the air to escape. Should that air find another way out of your vehicle, it will be much noisier. This is the common cause of most of the wind noise you’re probably experiencing right now.
Naturally, some vehicle designs are going to cut through the air with less resistance than others. This is referred to as aerodynamics.
A vehicle with better aerodynamics such as a sports car will inherently create less wind noise. On the other hand, larger or boxier designs like trucks and SUVs will create much more wind noise because they are creating greater disturbances in the air pressure as they move.
You know the air in your cabin is trying to get out and it’s supposed to go through specially designed discharge vents. However, the air doesn’t know what path it’s supposed to take. It will simply take the path of least resistance. Since the doors and windows are the largest holes in a vehicle, it’s safe to assume that they’re going to be a major culprit for air escaping.
Doors are surrounded by weatherstripping to create an effective seal against the air escaping. That seal is always getting smashed and flattened though, and eventually, it can be too crushed to be effective. Beyond this, they can also be subject to any other kind of damage such as dry rot, rips, and tears.
Any damage on your doors seals can render them ineffective. The same applies to the seals around your windows.
When you roll your window up, it gets sealed in by weatherstripping that surrounds the glass at the top. If that weatherstripping gets sun-damaged, cracked, or broken, the result will be the same. Air from inside your vehicle will use that space to escape, creating loads of excess wind noise that you probably don’t want to hear.
Once you know the cause of the noise, you will find some right ways to reduce the noise. So how to reduce wind noise in a car
I will give you 6 ways to do it
Locate the Cause
Before you can actually solve the wind noise in your vehicle, we must determine where it’s coming from. As we’ve established, the air leaving your cabin is going to look for the path of least resistance, which could be pretty much anywhere.
The first test is to simply drive down the road and listen. Keep the cabin quiet so you can hear well. Try to pinpoint which part of your vehicle the offending noise is coming from.
Next, get some passengers in your car, ideally several. Drive with the cabin quiet so each passenger can listen around their area of the vehicle for anywhere the noise is more concentrated. Make sure they listen around doors, windows, sunroof, all the corners of the cabin.
Repair or Replace the soundproof doors
Since the weatherstripping seals your doors and windows against the air escaping, they are some of the most likely causes of air leaks that create wind noise. If you have determined from step one the location of any noise, Open each door and window and inspect the seals all the way around. Look for any type of damage at all such as being crushed, ripped, torn, or no longer attached. Be sure to also check around the trunk and sunroof as well.
When you find damage, it’s time to do a bit of minor repair. If the weatherstripping is just unattached, you can use some weatherstripping adhesive to reattach it. Very simple
Check the Car Doors
You’ve checked the weatherstripping and everything seems to be ok. But, what about the doors themselves? Sometimes damage in the door can either stop it from closing all the way or create space where air can make its way into the vehicle. So the next tip on how to reduce the wind noise in a car is to check the car doors.
Begin by looking for signs of obvious damage such as major dents. If you have such damage, you may need to take your vehicle to a professional for repair if it’s beyond the scope of what you can repair yourself.
After checking for major damage, open and close each door. Make sure that it latches shut completely with no obstructions. 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 anything obvious that’s in the way, you may be able to use some cleaner or a metal file and fix it yourself. If it’s more than just a minor issue, you may need the help of a professional.
Install Sound Deadening Mats
These are thick mats that absorb sound and vibration helping to drastically reduce noise transmission in any vehicle including the wind noise in a car.
Sound deadening mats can be applied to the floor, doors, and even around the trunk of your vehicle to help reduce vibration and excess noise in your entire car.
To install them, you’ll need to get down to bare metal so you can adhere them to it. For doors, this means removing the door panels. On the floor, this means pulling up the carpet. In the trunk, you’ll have to pull out all of the panels and inserts to do it properly.
While this is certainly a time consuming and labor-intensive task, it’s also a very effective method at curbing all sorts of excess noise in your vehicle.
Use Wind Deflectors
Installing wind deflectors on your vehicle is one of the cheapest and easiest ways to drastically reduce the wind noise you’re experiencing right now. It’s a plastic piece that covers the top of your window and prevents the wind from hitting the area where your window meets the weatherstripping.
Wind deflectors are vehicle specific, so make sure to get the right ones to fit your specific vehicle. They are made for almost every modern car, so you should have no problem getting the right ones.
Install an Acoustic Windshield
The last trick on how to reduce the wind noise in a car is to install an acoustic windshield. Since the front of your vehicle is constantly being pushed through a wall of wind and air, it makes sense that the windshield, which takes the brunt of that air pressure, is a major offender when it comes to wind noise in the car. Swapping your current windshield for an acoustic one can do wonders for quieting the cabin.
Acoustic windshields provide other benefits besides just a quieter, more comfortable ride. For instance, they also block out more UV rays, as well as prevent the interior of your vehicle from experiencing sun fading
In this article I’ve told you about some of the causes of wind noise in a car, and have presented to you some helpful remedies so you know how to reduce the wind noise in a car when you experience it. These tricks will reduce repair costs when you bring the car to a garage. If you find the article useful, please share it widely on social networks.
Can door visors reduce wind noise?
It is a big yes to this question. Door visors can effectively reduce the wind noise in a car. In fact, car door visors work as wind deflectors and as a result, they are able to reduce the wind noise inside the cabin of a car. They can even give a better performance when you are driving at a high speed. But that’s not everything great about them. They can also upgrade the aesthetic look of your car while enhancing the aerodynamic stance of your car. So you can benefit a lot from door visors apart from reducing the wind noise in your car.
Do wind deflectors save fuel?
This is the question that is stuck in a lot of people’s minds when they are planning to use wind deflectors to reduce the noise caused by wind in their cars. The answer to this question is yes. Wind deflectors do save fuel when you use them. It depends on which type your car is to see how much fuel wind deflectors save for you. In general, you will get one to two miles per gallon better than you usually do.
