Why do you need to soundproof your car? If you do, what is the most affordable way to do it?
When you hit the road, soundproofing your car is the next best thing you want to do if you never want to ride in a noisy car. But more importantly, road noise is an annoying element while driving.
Using sound-deadening materials for your car is the best way to mitigate the sounds you hear around. We are not recommending a sound-free car but a vehicle that will eliminate nasty road noise while driving.
Most car owners would place carpets and foams to soundproof the trunk, but others use cost-effective materials. Why?
- DIY car sound-deadening materials are readily available.
- Car owners prefer DIY car sound deadening to save on cost.
- Car soundproof DIY saves you more time.
To know how to sound deaden your car, investigate where those noisy sounds originate.
The main component where the sound comes from is the engine. A roaring engine sound could mean that there is insufficient fuel going to it.
That’s why it creates a harsh, rocking noise. Damaged mufflers or dirty spark plugs also cause a pesty sound.
PRO TIP: Lubricating the car engine and its components helps in reducing rattling noise.
Poor road quality
Bumpy roads or roads with cracks and uneven surfaces add to the irritating noise in the car. Rough roads cause traffic. Poor traffic causes noise pollution.
Why? The sound of engines and horns from nearby cars is quite loud when your vehicle isn’t soundproof.
Because car tires rotate, they initiate sound with friction against the road surface. Air pockets trapped in between tire treads and pavement pop out due to pressure. Not fully inflated tires create a loud noise.
How Can You Get Rid of These Unwanted Noises?
The answer is simple: install car noise insulation materials.
Soundproofing your car can be done in different ways. How?
- Lay sound deadening pads on the floor.
- Stick insulation pads on car doors, including boot doors.
- Choose the best sound-deadening materials for cars.
Sound deadening materials for your car can be installed DIY. And this is a cheaper version to make your automobile soundproof. But before you make your hands dirty, it is better to be enlightened about how a soundproofing material works.
First, you need to know what to look for in sound deadening material.
- Sound isolation purpose: Sound-deadening materials can either serve as a sound blocker or sound absorber. The description of sound isolation is relatively intuitive. And obviously, you want both functions if you wish to get away with rattling sounds.
If you are more concerned about the type of sound that will resonate inside your car, meaning, if you are keen on enhancing the sound of your car speakers, you would prefer a sound absorber. Of this type, music from your speakers will sound better, with a more thumping bass sound.
- Type of material: Sound insulation materials also come in different styles or feels. The usability of these materials may overlap in terms of absorption levels of resonance, sound waves, and vibrations.
- Mats—These sound insulators are laid to cover car floors and panels.
- Foams—Can be used along with a soundproofing mat or placed underneath the carpets. They serve as sound deadening pads because they absorb sound. However, foams are thicker and bulkier, adding weight to your car.
- Sprays—Sometimes, laying mats and foams is complicated for tricky areas, such as doors and farthest corners and crevices on the car floor, so sound deadening spray insulation is another option for such situations.
Spray insulation is also excellent for sound deadening when used in dampening machines, but it isn’t as effective as foams and mats for softening irritating sounds.
Of the three types of materials, mats and foams work in many ways. Aside from isolating sound, they also serve for keeping the temperature inside your vehicle.
While we aim to emphasize cheaply soundproofing your car, we will persist in recommending DIY car sound deadening.
PRO TIP: Having the right soundproofing product will do the job of making your vehicle quieter.
1. Noico Car Sound Deadening Mat – For Car Engine
Noico Car Sound Deadening mat is a 2mm, 36 square feet mat made of butyl rubber and foil for automotive sound deadening and heat insulation.
Noico Solutions manufacture this product. Each box contains nine sheets with 29.5 x 19.5 inches that can cover a maximum area of 36 sq ft. The package does not include a sound deadening roller.
You can only install the mat from the interior side of the car. Before affixing the mat:
- Make sure that the surface is clean and dry.
- Rub the surface with a cleaning agent to have better adhesion.
- Conduct a test fit before peeling off the protective film.
- Flatten the mat along the surface using your thumb and a roller to ensure no air bubbles are present.
The butyl rubber and aluminum foil mat insulate and deaden sound effectively, as its density and thickness enhance its absorbing power on sound and vibration.
This car insulation mat is cost-effective as it is 20% cheaper than its competitors; it is 1.5 times thicker for better insulation with its 80 mil feature and an optimal weight to achieve maximum soundproofing.
The Noico Car Sound Deadening Mat is easy to install, self-adhesive, and comes in a metallic finish.

Excessive noise comes from different sources, whether these are airborne noise, car parts noise, or road structure complications that affect your cognitive function even in driving.
While you have control over our automobiles, you can reduce the impact of unwanted sounds by opting for soundproofing materials that won’t hurt your budget.
By now, you have compared the best deals in sound-deadening materials for your vehicle and have known how to DIY car sound deadening.
However, as most of the products come with a kit, it is more likely to avail a sound deadening roller easily. Nevertheless, it should never be a problem since most of these materials have quick and straightforward installation manuals to follow.
The next best thing to learn is to carefully remove interior parts such as seats, speakers, and other components to access the entire car floor. Then, when you’re all set, start reducing road noise for good.
