Is It Worth Sound Deadening a Car?

If you are still in doubt about the benefits of using sound material in your car, hopefully, this section will help you overcome your doubt. The idea of sound deadening a car might cross each car owner’s mind at least at one point in time while driving through a busy road.

The loud noises that interrupt the calmness that we crave in our vehicles make us uncomfortable during traveling. And that is why sound deadening a car is actually worth it! There might be certain benefits of soundproofing your car, but it cannot be denied that there are certain disadvantages too!

In this section, we are going to discuss both the pros and cons of installing sound deadeners in cars. Have a look below…

Pros of Installing Sound Deadener in Cars:

  • Reduce Road Noise: Most of the road noise is caused by car engines, tires, exhaust noise, etc. And it can drain the sound of your communication or music system inside the car. Luckily, the car sound deadening material covers all the road noise that comes while driving.
  • Improves the Acoustics of the Car: If you are thinking whether it is worth deadening a car, then know that it definitely is! Using a sound deadening material in your vehicle ensures the car cabin works as a speaker enclosure for your car speakers by sealing the gaping holes and reducing the resonance. This way, the acoustics of the car is also increased!
  • Make Driving Comfortable: The material of a car deadener also works as a good insulator. Thus, installing sound deadening in the car not only ensures that you have better soundproofing but also makes your ride a comfortable one!
  • Reduces Rattling: When the car moves, rattling and vibrating of the car panels are very common. But when you install a car deadener in your car, it makes the car panels dense and thus does not contribute to rattling too much. This is also one of the significant benefits of sound deadening insulation of the car.

Cons of Installing Sound Deadener in Cars:

  • Weight Increment: Even the best automotive sound deadening material for cars would come with a weight that adds more mass to the car. And it is likely that if your car is more weighty, it will consume more fuel. Thus, this is a disadvantage of installing a car deadening material in your car.
  • Labor-Intensive Installation Process: The installation of the deadening material takes a lot of labor and time. Sometimes it can take days to complete the installation process, which is definitely one disadvantage of the sound deadening process.
  • Deadeners Cannot Be Reused: While installing; the sound deadeners take both time and effort to be installed; one disadvantage is that they cannot be uninstalled and reused if you are changing your car or if they are damaged. So, it is a one-time usage material and, thus, not too cost-effective.

How to Choose the Right Sound Deadening Material for Cars?

When buying a sound deadening material, there are certain things that you must look out for to make sure you pick the right choice. And to help you choose the best deadening material, here we present the essential things to consider before buying an automotive sound deadening material for cars. Get going…

Types of Sound Deadening Insulation

This is one of the most crucial things to look for in a sound deadening material for cars. Sound insulation is of two types; the sound absorbers and the sound blockers. The sound blockers are meant to block the getting in and going out of any kind of noise from the surrounding space!

While the sound absorbers are the types of insulation that ensure the sound that gets inside the vehicle becomes softened and gets absorbed after that.

Most deadeners have both these properties, but some may be specific. So, when you are picking up a sound deadener material for your car, you better look for the best option from these insulation types.

Types of Sound Insulation Materials

The automotive sound deadening materials decide their effectiveness in controlling the sound that gets in. There are four types of materials that are considered best for the purpose.

  • Deadening Mats: These are the most effective and popular choice amongst car owners to prevent extra noise inside the car cabin.
  • Sound Dampening Sprays: often the left out material, the sprays are only used if at all regular placing mating is not possible inside the car cabin.
  • Foam Insulation Products and Woven Fiber: the combination of these two types are also often used when people need extra sound cancellation, even after placing deadening mats.

So, choose your material types wisely to get maximum efficacy!

The Thickness of Sound Deadening Material

The thickness of the deadening material matters, of course, when you are trying to think how to choose the right automotive sound deadening materials for your car! When selecting a deadening mat, look for a thicker one.

As we all know, the thicker the mat, the better sound-canceling it will provide inside the car cabin. But if you do not find a thicker mat upon searching, then you can also settle for multiple thinner deadening mats that would deliberately serve a purpose.

All you need to see is the sound is blocked with thicker deadening material and not a thinner one for best results.

Shape and Size of the Sound Deadener

The shape and size of the material are also very important things to consider when buying a car sound deadening material. When you are going to buy a sound deadening material for your car, you first know which is the best-suited size for the purpose.

car sound deadening material

Like if you have a bigger vehicle, you will need a bigger size and vice versa. While some sellers prefer to sell the deadeners as sheets or patches, some have them rolled up. The rolled-up ones need to be cut according to the size of your car cabin floor, and that can be time taking. Going for the sheets or patches is a good option if you have a small car to deaden.

The Odor of the Sound Deadening Material

You might find it a weird criterion when choosing the best sound deadening material for cars and trucks, but yet it is one of the significant factors to look at! When traveling in your car, you would simply not be able to tolerate a bad smell, right? And placing a sound deadening material that would protect you from loud noises and provide you a foul smell instead would not be a nice thing to get in exchange, right? So, choosing such materials that have the finest odors is always a good idea over choosing a foul-smelling material just to save a few bucks. Apart from protecting you from loud noises, it will also ensure you breathe fresh!

Weight and Flexibility of the Sound Deadening Material

Are you still wondering what to look for when buying a sound deadening material for cars? Well, this one last thing is good to consider if you are looking for more options! The weight and flexibility of the sound deadeners decide a lot about its installation process. The lighter the weight of the deadener, the more easily it will be installed. The same applies to the material’s flexibility; the more flexible it is, the easier it is to install. Also, when you buy a lightweight deadener, it makes your vehicle less heavy, resulting in less fuel consumption. So, now you know which are the things to look out for when buying a sound deadening material for your car!
