Wind deflectors, also known as window visors or rain guards, are popular accessories for vehicles. They serve various functions, such as reducing wind resistance, allowing fresh air circulation, and keeping rain out when you crack your windows. While they offer many benefits, one common concern among vehicle owners is whether wind deflectors cause noise. In this blog, we will explore this issue in detail, addressing questions like, “Do wind deflectors cause wind noise?”, “How do you stop wind deflector noise?”, “Do weather shields reduce wind noise?”, and “How will wind deflectors affect your vehicle?”

Do Wind Deflectors Cause Wind Noise?

The short answer is yes, wind deflectors can cause wind noise, but it’s typically minimal and manageable. The noise primarily occurs when air hits the deflectors as your vehicle moves, resulting in a soft whooshing sound. The intensity of the noise can vary depending on factors like the design of the wind deflector, the speed of your vehicle, and the direction of the wind.

How loud this noise is and whether it bothers you largely depends on your sensitivity to such sounds. Some drivers hardly notice it, while others may find it distracting. Fortunately, there are ways to mitigate wind deflector noise, and we’ll discuss them shortly.

How Do You Stop Wind Deflector Noise?

If the noise from your wind deflectors is bothering you, there are several steps you can take to reduce or eliminate it:

Proper Installation 

Ensure that your wind deflectors are correctly installed. Sometimes, improper installation can cause them to vibrate or create more noise. Double-check the manufacturer’s instructions or seek professional installation if needed.

Choose the Right Wind Deflectors

Not all wind deflectors are created equal. Some designs are quieter than others. Consider purchasing a reputable brand with a design optimized for reduced noise. Look for deflectors with smooth, aerodynamic shapes.

Add Foam Strips or Weather Stripping

 Applying foam strips or weather stripping to the edges of your wind deflectors can help dampen vibrations and reduce noise. This is a cost-effective solution that’s easy to implement.

Reduce Speed

Wind noise from deflectors tends to increase with speed. If the noise is bothersome, consider reducing your driving speed when it’s safe to do so. This can significantly reduce the noise level.

Close the Windows Slightly 

If you’re using wind deflectors to allow fresh air in during rain, try closing the windows slightly. This can minimize the gap through which wind enters and, in turn, reduce noise.

Experiment with Placement

Sometimes, minor adjustments in the placement of your wind deflectors can make a difference. Try moving them slightly and see if it affects the noise level.

Use Wind Deflectors in Combination with Other Accessories

Combining wind deflectors with other accessories like roof racks or spoilers can sometimes help redirect airflow and reduce noise.

Do Weather Shields Reduce Wind Noise?

Weather shields, also known as window weather deflectors, are designed to protect your vehicle’s windows from rain and wind. While they serve a similar purpose to wind deflectors, they are typically narrower and closer to the window’s surface. This design can help reduce wind noise compared to traditional wind deflectors.

Weather shields are often more effective at reducing noise, especially at lower speeds. They create a smoother airflow around the window, minimizing the turbulence that causes noise. However, it’s important to note that the noise reduction may not be significant at high speeds, as some wind noise is inevitable when driving at faster rates.

How Will Wind Deflectors Affect Your Vehicle?

Wind deflectors offer several benefits to your vehicle, but they may also have some implications that you should be aware of:


Wind deflectors can improve the aerodynamics of your vehicle, reducing drag and improving fuel efficiency. This can lead to cost savings over time.

Fresh Air Ventilation 

Wind deflectors allow you to crack your windows slightly without rain entering the vehicle. This is especially useful during rainy weather, as it can help reduce the need for air conditioning.

Reduced Interior Heat

By allowing fresh air to circulate even when the vehicle is parked, wind deflectors can help prevent your car’s interior from becoming excessively hot on sunny days.


As discussed earlier, wind deflectors can cause some wind noise. However, this noise is typically minimal and can be mitigated with the tips mentioned above.

Aesthetic Appeal 

Wind deflectors can enhance the look of your vehicle, giving it a sleek and sporty appearance. Many people find them aesthetically pleasing.

In conclusion, wind deflectors can cause some wind noise, but it’s usually manageable, and there are ways to reduce or eliminate it. Choosing the right wind deflectors, proper installation, and experimenting with adjustments are key steps in addressing wind deflector noise. Additionally, weather shields can provide similar benefits with less noise due to their design. Ultimately, the impact of wind deflectors on your vehicle will depend on your specific needs and preferences, but when used correctly, they can enhance both the functionality and appearance of your vehicle.
