Best Soundproofing for Cars

If you are beginning to get fed up with the sound of your car engine and the road beneath your vehicle, it might be time to consider solutions for the best soundproofing for cars. Road noise alone can make the driving process less than relaxing, while exhaust drone and engine noise add even more of a racket into everyday driving. If your car has a few years on it chances are that it is nearly impossible for you to have a conversation at normal speaking volume while driving down a gravelly road or rattling along the motorway.

The main thing to understand when soundproofing your car is that it is practically impossible to cancel out all outside noise. You will still be able to hear noise from the road escaping into your car as you drive, especially in older vehicles, so don't count on a completely noise-free experience. There are various soundproofing materials on the market today.

At best, many of the products are satisfactory and truly useful for soundproofing, and at worst some are of unsure benefit to homeowners and businesses. Most car owners are always questioning how they can deaden such noise and find the best soundproofing for cars. The solution is fitting your car properly with an effective sound deadening material. There are loads of sound deadeners available out there. Thus, it’s not that easy to select the best one to fit your needs.

Buyers Guide

There are numerous factors that may prohibit you from getting a perfect trip. The main cause in this case is noise. As your car moves, the roaring engine and wind creates a ton of noise. Also, there might be vibrations as the car moves along rough roads.

Thus, most car owners are always in search of how they can acquire the best soundproofing for cars. The solution is simply customizing your vehicle with an effective sound deadening material. There are dozens of sound deadeners available out there; hence it’s not that easy searching for one that completely works for you.

Luckily, we have prepared a buying guide on the best automotive sound deadening material. So, worry no more! Just read through this buying guide.

Pre-Purchase Considerations

Automotive sound deadening materials not only have their fair share of individual requirements, but they can also be highly expensive. Because of this, purchasing materials that don’t end up working for you can be an aggravating and costly mistake.

Fortunately, these challenges are simple to avoid with the right amount of research. Below, you’ll find everything you require to take into consideration before spending your hard earned money on a soundproofing material.

How to Install Sound Deadening Material?

Sound deadeners generally come in four different forms:

  • Insulation
  • Mats
  • Foam
  • Sprays
  • Floor: – remove the carpet, and then proceed to clean the floor thoroughly. Apply the deadener only after the floor is cleaned. Once applied, and then put the carpet back on.
  • Roof: - remove the cloth headliner and thoroughly clean the roof with rubbing alcohol. Apply the sound deadener and put the headliner back in place.
  • Trunk: – remove all items you have in the trunk and any floor fabric or carpet. Apply the material after cleaning the trunk.
  • Firewall: – dismantle the dashboard and then proceed to clean. Apply the deadener and then reassemble the components you separated.

How to Remove Sound Deadeners?

Just because a sound deadener is uncomplicated to install doesn’t mean it’s easy to remove. In fact, this is the case for many products, particularly those that boast easy installment.

While the amount of time it takes to remove the material depends on the type of car, the process shouldn’t take more than an hour when utilizing the correct tools.

Utilize about 20 pounds of dry ice, sprinkle enough to cover the tar. Afterward, gently tap it with a rubber mallet or small hammer.

Many people end up heating and scraping the material in order to remove it. However, not only does it take a lifetime to remove, but it also creates an enormous mess.

Type of the Insulation Material

There are various types of materials utilized in designing sound deadeners. They absorb or insulate against noise in different ways. Being aware of their differences will assist you to know the perfect sound deadener to use in different areas of your car. The major types of noise insulation materials include:

  • Damping Mats- These mats are most common and are perfect for application on panels.
  • Insulators- They’re generally made of fiber cloths. They’re great for absorbing noise from beneath the car carpets.
  • Foam- Foam is most effective for deadening reverberations in the cabin. Foams are typically available in form of sheets.
  • Sprays- Sprays are suitable for application in areas where mats cannot be utilized. They’re also the least common noise deadeners.

Weight and Flexibility of the Material

Different deadeners weigh differently. Preferably, opt for a lightweight material for an uncomplicated installation. Lightweight materials are effortless to fix since you’ll not exert much energy and effort to fit on any surface. A significantly flexible material will allow for easier installation. You’ll easily bend it around irregular car surfaces, something which is extremely common about cars.

Thickness of the Sound Deadener

It’s pretty obvious that thickness matters a lot with regard to insulation against noise. Thicker materials are much better at deadening sound than thinner ones. You can even make use of multilayered material for enhanced sound deadening.

Size of the Material

Different sound deadeners come in tons of different sizes. The size you should purchase should depend on the extent of the area you’re planning on insulating. Some of them come as rolled mats such that you can cut out the size you require. That means that you can cut them however you want in order for them to fit a certain shape. Others come as pre-cut sheets although the size of the sheet to purchase should also depend on the area you need to cover.

Method of Noise Isolation

Before you make a decision, you should know the method of noise isolation that the material utilizes. First, you need to know that soundproofing is not the same as sound absorption. A soundproof material reduces outside noises from entering into the car. Such noises will include traffic noise, wind, humming of the tires as well as road vibrations. Thus, if most of the noise is coming from outside, a soundproofing material will work much better.

Materials that absorb noise generally absorb noise from within the car such as rattling of the trunk, loud motor, and cabin noise. If most of the noise in your car is coming from the inside, then you should probably opt for a material that absorbs noise.

Nevertheless, you can also integrate the materials. For example, you can utilize sound absorbing materials on the cabin and trunk and use soundproofing material on the doors, roof and floor.

Is it Odor-Free?

As mentioned earlier, materials that don’t function well in high temperatures are more prone leave behind foul odors when exposed to the heat. However, that doesn’t make them the only materials that can develop a smell.

Many other materials develop strong odors during the installation process and even after the adhesive have been applied. While this may only last for a limited period of time, it still isn’t the most comfortable situation.

Plus, some materials have a persistent odor, even if faint. For instance, a couple is known to have the scent of a newly paved road.

Does Heat Impact the Material?

Many different sound deadeners don’t react well with the heat, which makes them a bit impractical for people living in warmer climates.

When these deadeners come into contact with high temperatures, their materials can melt; leave behind terrible odors, or more.

However, soundproofing materials with adhesive tend to work extremely well in hotter weather, with the heat not having a significant impact on their effectiveness.

Final Recommendation

Ultimately, if you’re searching for a good and reliable sound deadening mats for your car, I’d stick to Dynamat or Noico. Those two are the most well known and also the best soundproofing for cars on the market by far. However, Noico is certainly the more affordable and even the thicker option — it’s definitely the fan favorite.

Of course, that’s not to say that the liquid insulation and the other materials you can utilize to minimize the noise in your car are in any way bad. Still, we clearly know more about the effects of sound deadening mats than we do about any of the other materials I’ve mentioned. So at least when you decide on purchasing Noico, you’ll know exactly what to expect.

Final Verdict

In conclusion, it’s clear that there’re many different types of sound deadeners to choose from. Avoid selecting a material based on price alone. Purchasing a material just because it’s cheap and affordable may lead you into choosing a low quality sound deadener.

Again, an expensive material doesn’t necessarily mean that it’s a superior product. Thus, you should always balance between price and quality. Hence, consider other key factors such as size of the material, thickness, flexibility, and method of noise isolation among other factors mentioned previously. By keeping this guide in mind, you’ll automatically stand a better chance of getting the perfect automotive sound deadening material as well as the best soundproofing for your car.

Also, remember that each material comes with its own unique benefits and some disadvantages. Thus, invest in the material that provides the kind of features you require and the shortcomings you can live with for the best sound isolation in your car. That way, you can enjoy improved music in your car while being in a much more comfortable car environment.

Hopefully, this article has helped you be more informed and aware on the subject of automotive sound deadening materials. No matter which of these materials you end up selecting, you’re driving experience is sure to improve dramatically once you have them put in.
