Road noise refers to the sound your tires make while driving. And while tires may be the main culprit here, the make of your car can also cause unwanted noise in the cabin. Below are some options to deaden the disturbances.
1. Use Soundproofing Mats on the Floor
Diving on a highway at a high speed will naturally produce noise, especially if you’re cruising atop battered roads (often the case, unfortunately). A simple fix to deaden the tire’s sound on the pavement is to invest in Soundproofing floor mats.
Quality floor mats absorb the sounds that reverberate on the floor of your car, and they help lower the interior temperature. While designed specifically for the floor, they can be placed wherever needed, from the trunk to the roof.
These mats, also called vibration dampeners, are easy to install. To properly place them on the floor, lift up the existing rubber mats and put these thick pads underneath. Many brands promise at least a 50% reduction in noise, allowing the tunes you play in the cabin to sound crystal clear.
2. Use Soundproofing Spray
Of course, there are small, hard-to-reach places on the floor of the car that might not be coverable with a sound-deadening pad.
For tight, awkward spaces, try a spray or foam that can help dull extracurricular sounds. This isn’t a solution for the entire car, mind you, but these options are ideal for those tiny spots that a mat can’t cover. Examples of areas of the car in which sprays or foams can help deaden the sound include on the body paneling, the rear quarters of the vehicle, the undercarriage of the vehicle, and inside the trunk.
Spraying creates a barrier between the cause of cabin disturbances and can enhance the musical experience heard inside the car.
The top-of-the-line sprays on the market will effectively eliminate noise and vibrations from these spots. Just one can will cover 20 square feet of the car, which is more than most car owners need.
3. Undercoat Your Car
A similar approach to soundproofing cars is to undercoat the underbelly of the vehicle. While sprays and mats are designed for the car’s interior, it’s important to protect the exterior as well, since outside is where the noise originates.
Undercoating cars with a rubber spray gives them an extra layer of protection against unwanted sounds. Not only is this a good technique for reducing road noise in the vehicle, but it protects the underbelly against rusting, abrasions, and damage from salt.
Rubber undercoating is accomplished via an aerosol spray bottle, just like the aforementioned sprays that can stop unwanted sound in its tracks. Both tactics offer easy application, and the individual bottles are economical, but you may need more than one to cover the whole underbelly effectively.
There are plenty of undercoating options available online, and many of them are capable of coating up to 15 square feet of the vehicle. Once dry, you can get back on the road and enjoy the sound of increased silence.
4. Change Your Tires
Check those tires if you hear an excessive amount of road noise. After all, they’re the only parts of the car that are always on the road, so make sure you have the correct make and model to reduce noise.
Again, each car model is specialized, so check other possible road noise sources before investing in a brand-new set of tires. If you suspect the tires are causing the unwanted racket, find ones that …
- Are narrow
- Are smaller (16-inch wheels are ideal)
- Have tiny, tight-set grooves
- Are made of soft rubber (the softer, the better)
Keep in mind what your priorities are when selecting tires. Many wide tires with large grooves offer increased traction on tough terrain. Likewise, larger wheels may drive better depending on the car you own.
If you’re an off-roader and need heavy-duty tires, soundproofing them probably won’t matter. Nevertheless, be sure to change your tires regularly so that the everyday wear and tear doesn’t cause excess noise in the cabin.
