Cars are the biggest green flag — for a car lover, there can be nothing more dear to him than his four-wheeler. Whether you buy an all-new car from the showroom, or a used car from your nearby auction, such as Jefferson auto auction Wisconsin, a car is one of your biggest investments. Despite all this, there is one thing about these vehicles that needs to be worked on. 

And that is NOISE. While traveling in a car, noise is so common that we almost ignore it, which should not be this way. Luckily, with more advanced tech and innovations, there are some ways you can tackle vehicle noise pollution. If talked about broadly, you can either go for an EV or install several modifications in your car to reduce the noise. 

Therefore, diving straight into its details, let us discuss all the mediums through which you can get rid of your vehicle noise.

Shift Your Preference Towards Electric Vehicles

Mercedes EQS

There is no doubt that EVs are not a concept anymore. In fact, there are numerous ways in which EVs are somewhere more technically advanced than traditional engine cars. 

Referring to a real-life example, the Mercedes EQS 580 is the flagship EV from the company. There is so much tech installed in the car that outfunctions almost any traditional engine car, The EQS 580 has 350 sensors, a Mbux hyperscreen, active ambient lighting systems, and safety and driver’s assistance technology. It also has automatic comfort doors and an air control option.

Speaking of noise pollution, an ICE (internet combustion engine) car is may more noisy than an electric one. You can see these noise levels in the graph below:

Here, you can see that in traditional vehicles, the engine is the biggest contributor to all the unwanted noise, followed by other factors such as inverter & motor, transmission, etc. Whereas in EVs, roads & tires are the biggest contributors to cabin noise.

If you want to further reduce the noise in your electric vehicle, you can go for the active noise control feature. Being one of the most efficient practices to reduce unwanted noise, this technique uses microphones to record those unwanted frequencies and speakers to negative the sound to counter them. 

Try Vehicle Dampening

If you are a car enthusiast, you must be aware of vehicle dampening. If explained in simpler terms, car-dampening involves installing noise-absorbing material in your vehicle body to achieve a minimum level of frequency. 

There are panels cut into the shape to be pasted on the areas with maximum vibrations. These areas include door panels, pillars, roof, and floor of the vehicle. It not only reduces the frequency level but also helps in reducing the potential echo that may bounce off any hard surface of the car. 



Rolls-Royce, known for its luxury cars and jet engines, once made their car so quiet that it started making their drivers feel nauseous due to low frequency. The car used multiple KGs of sound-absorbing materials that almost cut down all the noise. 

Why You Should Go for Car Damping: Pros

There are plenty of advantages that you can enjoy if you get your car damped. Some of them are listed below: 

  • Car damping results in lowering the level of car rattling since the majority of rattle is absorbed by the acoustic foams, staples fibers, etc.
  • Offers you a better acoustic experience and silent road experience. The squishy foam of the damping absorbs the sound made from tires.
  • Since the hard surfaces are softened by the foam and squishy materials, it also makes the ride more comfortable and sound-deadning.
  • Lastly, if you are a filthy rich individual with a chauffeur-driven car, you can enjoy the real luxury of a silent ride, which will also soothe your mind with no unwanted noise. 

Why You Should Refrain from Car Damping: Cons

Just like any other thing on the planet, car damping also has its own cons as well: 

  • The process of getting the damping installed in your vehicle is really time-consuming. The progress is directly related to the amount and the speed of labor put into the process.
  • Since the labor is directly involved, going for quality service is primary for a long-lasting experience. This high-quality service also results in expensive and costly procedures.
  • Since the material is installed all over the car’s body, it ultimately increases the weight of the four-wheeler, which ultimately results in lesser fuel economy. 

Some Additional Tips for Better Vehicle Noise Reduction

More to these 2 major technologies that are extremely useful in the purpose, here are some additional tips that you can also practice: 

  • Go for Quieter Tires: There are special quality tires manufactured by companies that you can go for. If you want to know what features a quiet ties has:
    • Circumferential ribs that have straight grooves and better to reduce noise.
    • Diverse tread block shapes that create a multiple-pitch pattern.
    • Blocks that are smaller. 
    • A reinforced shoulder to stabilize the tread blocks.
    • Small-sized hash marks inside the grooves that help in breaking up the air flow.
    • Narrower tires are comparatively quieter.
    • Softer but sturdier material.
  • Refrain from Honking: Honking is not good. Be it for noise pollution or fuel economy, honking is not at all appropriate for any situation. You must use the horn to ensure safety while driving on the roads, but consider avoiding it when not in need.
  • Turn off Vehicle Engines: Whenever the signals turn red, consider turning off your car engine so that you save on fuel and also enjoy silence.


Finally, these are some tips that you can follow to reduce unwanted vehicle noise. Make sure that when going for car damping, you have to go for a good quality service irrespective to the cost & price.
