Even with a brand new car, there are some unwanted sounds that no one wants to deal with when they are driving around. It gets particularly noisy on highways, but it can be a bit of a problem in residential areas as well.
One way to kill those sounds and have a much better experience overall is to soundproof a car.
While manufacturers are doing quite a bit to make sure that the car sounds pretty good right off the lot, there are others who are going to want to take it another step.
In this article, you get an opportunity to see exactly how much it costs to soundproof a car in various ways.
Some will work for specific situations better than others, which is why there is no one-size-fits-all setup. It’s important to try a few things and see if it ends up being best.
Doors can be one of the most frustrating parts of a car when it comes to sound. It’s one of the easiest ways for sound to enter, and manufacturers don’t always put the best type of material to kill sound in there automatically.
Soundproofing material that is very popular for doors includes using a mat, spray, or some type of foam.
All of the solutions work to a certain degree, but it’s recommended to opt for the latter two, since it can be hard to lay a mat down just right.
Keep in mind that it is generally recommended to treat all four doors in a traditional car. If there are any compromises, at least soundproof the front two doors.
Soundproofing the Trunk
Another vulnerable area for sound is the trunk. Since it’s not shaped the exact same way as the other parts of the car, it might not have the same type of soundproofing materials already installed.
That’s when a person needs to take it upon themselves to make sure that the sound is not too much to handle on a regular basis.
A trunk is a much easier spot for people who want to use mats since the whole area can be lined with the sound deadening pieces.
If it is done from the very beginning, it can make for a very easy process in general. They are going to mostly stay in place, but use some adhesive that’s easy to clean up to put it up against any sides that need extra treating.
Mats are easy to put all around the trunk, and they stay mostly hidden during regular use.
Soundproofing the Interior Floor
Road noise coming from below is one of the biggest complaints people have when they are driving.
A brand new car can be a little problematic with the interior floor, as there is so much noise coming from below.
Road noise and heat will do a lot of damage, so that’s when reflective insulation options are the way to go.
Soundproofing car mats will be very effective in controlling sound. As well as the mat, using reflective insulation underneath is going to help even more.
It looks a lot like tinfoil, but it’s going to help with deadening the noise that is inside the vehicle. Not only that, but it also helps as a way to control temperature even more with another barrier.
That means the car will stay warmer in the winter, and cooler in the summer.
The great thing about applying anything to the ground is that gravity can be used as a pretty convenient way to keep everything in place.
All it takes is a little bit of adhesive or Velcro to keep it all in place as well so that everything is not moving around.
Treat it well, and sound-absorbing mass insulation will last for a very long time. They need to be a little bit durable since so many people are stepping on it all the time, but it does the job the way it should.
Make sure not to leave any gaps on the ground, because it will really hinder the soundproofing performance of the material.
Try to cover the entire area and use up as much material as possible so that everything is protected. That way, there is no need to go back and make any changes along the way.

Anyone really looking to enjoy music will definitely benefit from soundproofing. One of the reasons why people have to turn up their speakers so much is because there are so many distracting noises drowning out what they want to hear.
You end up being the distracting driver that everyone else hates because the music is way too loud.
This benefits both the driver and everyone else, because the volume doesn’t have to be as high to get even better sound.
Way too many people invest in brand new speakers for their car, only to skimp on something like soundproofing.
