So sit down, take some notes, and let’s get to it!

Table of Contents

What You Will Need

Here is a list of each material you’ll need to complete this project:

  • Constrained Layer Dampening (CLD) materials or sound deadening mats. This will help deal with structure-borne noise.
  • Mass Loaded Vinyl (MLV). These are very flexible, great for vehicle applications. Mass-loaded vinyl will help deal with airborne noise.
  • Closed Cell Foam or acoustic panels if you want to cut corners. This will help to deal with noise rattling.

The approximate cost is $420. This is just an estimate, though, and if you look for the cheapest deals, you can definitely reduce that cost by A LOT.

You can find most of these from places like hardware stores. If you can’t find them from hardware stores, go ahead and look on online stores like Amazon, eBay, etc.

Best Way to Soundproof a Truck Cab: Step-by-Step

So now it is time to finally start soundproofing our truck cab. This should be the BEST soundproofing method for a truck cab.

There are different surface areas of the truck cab you will want to consider for soundproofing.

Here are the steps on how to go about soundproofing a truck cab.

Step 1: Cabin Floors

The cabin floors is the number one thing to prioritize. If soundproofing only one area is your only option, this would be it.

This is because most of the vibration and noises come from the tires of the truck, which are located underneath the cabin floors.

Tires cause structure-borne noise, as well as road noise. Noises from transmission also originate from the bottom.

Here is a step-by-step guide on how to soundproof your cabin floor.

  • Remove all the seats, the carpet, and all the trim pieces. This is to have CLEAR ACCESS to the floor of the truck cabin.
  • Add your Constrained Layer Dampening (CLD) materials or sound deadener. This would be your sound deadening mat. You just have to cover the problem areas, which are thin panels that vibrate the most. Pay special attention to the areas under the feet of the driver and the passengers.
  • Cover the entire floor with Mass Loaded Vinyl (MLV) or something similar to rubber mats. This will help to deaden the airborne noise or road noises.
  • Line the trims on the floor with closed-cell foam or acoustic panels.

After completing all these steps, the floor of the truck cabin should be soundproof. The sound of the tires shouldn’t be a bother anymore!

If structure-borne noise is the only noise that annoys you, then you can stop here. You don’t have to move on to the following steps anymore. 

Step 2: Car Doors

After the floor, the next priority is to soundproof the doors.

Basically, use the same concept as the floor. Add high mass sound barriers and sound-deadening material such as mass loaded vinyl (MLV) and closed-cell foam to the interior of the cab doors.

Just DON’T COVER the windows, because you need them to see when you drive. This means there’s still going to be some airborne noise, but the airborne noise structure should still be significantly reduced.

Once you’re done with this, the car doors are officially soundproof.

Step 3: Back Wall and Roof

After you’ve taken care of the noise coming from the floor and door, the last step is to soundproof the back wall and roof.

This takes on the same concept, with CLD material and sound deadener.

However, if you want to cut corners for your back wall and roof a little, you can skip the Mass Loaded Vinyl (MLV) for the roof. The layers of CLD material and closed-cell foam should do the job.

To save a bit of money, you can opt to use SOUNDPROOF PANELS for these instead of closed-cell foam.

This is the final step to soundproofing a truck cab.

The steps were not so difficult AT ALL!

Tips:

  • Make sure the surfaces are CLEAN before adding soundproofing material like CLD material or sound deadener.
  • Use a SMALL ROLLER when sticking on the soundproof material for a smooth finish.
  • AVOID asphalt-based Constrained Layer Dampening (CLD) material, as most tend to melt in high temperatures.

Soundproofing Challenges

Some would recommend just covering the interior of your truck cabin with acoustic panels. But just to let you know, this is NOT how you should approach this.

You want to look at the different challenges when it comes to truck soundproofing and figure out what material can handle each challenge when it comes to soundproofing a truck cab.

So before we go about soundproofing a truck cab, it’s important to understand the main noise causes in the truck and how to reduce that noise.

Noises can come from different places — from ongoing traffic to the truck itself.

Structure Borne Noise

Structure-borne noise is caused by the interaction between the tire and the road.

When driving, the structure-borne noises from the wheels travel to the cabin through the suspension system. Cars with a good suspension system tend to have less structure-borne noises coming from the wheels.

In most trucks, this is the main problem that will have to be tackled.

To deal with a suspension system issue, you will need Constrained Layer Dampening (CLD) material or sound deadeners.

CLD stretches to control vibrations by converting kinetic energy into heat energy.

If structure-borne noise is the ONLY noise from your truck that irritates you, then you only need to add sound deadening mats to the cabin floor.

Road Noise or Airborne Noise

These are probably the most ANNOYING noise. At least in our opinion. Imagine driving in traffic and hearing all the loud horns of impatient drivers. Sheesh. It’s like we’ve dealt with this EVERY. SINGLE. DAY.

But you can easily fix this problem with soundproofing.

Different from structure-borne noise, airborne noise is mainly traffic and horns. For airborne noise, you NEED sound barriers.

The way to deal with an airborne noise problem is to use a material like Mass Loaded Vinyl (MLV).

Noise Caused by Rattling

Things that cause this sound are interior trimmings and its doors. This requires the most attention.

It can also be caused by parts inside the cabin hitting each other.

It’s kind of concerning if you hear this. So before you go on to soundproof your entire truck cabin, go ahead and check if anything is falling apart in your cab. If all is good, then go on and soundproof.

A sound-deadening material such as closed-cell foam should do the trick for this problem.

Why Would I Want to Soundproof My Truck Cab?

There is a reason, or plenty of reasons, why soundproofing a truck cab would appeal to someone.

Here are some common reasons.

1. Noise-Free Rides

Sometimes, the different airborne and structure borne noises around you when driving can cause such a headache.

If you soundproof the truck cabin, there will be more peace and quiet. This is one of the numerous benefits of soundproofing your truck cab.

This is probably the most POPULAR reason for wanting soundproof trucks.

This reason is mostly for introverts or people who want peace and quiet in general.

2. Conversations Without Disturbing Noises

Aren’t conversations nice? Don’t you wish you could have quiet conversations while driving? Well, with soundproofing, you can.

Soundproofing is one of the ways someone may be able to be more social in their truck.

If you have a friend sitting in the passenger seat, having a quiet truck will be more pleasant if you like to have a conversation.

Building peace and friendships is ALWAYS a good thing!

3. Better Sounding Music

Did you know that sound absorption can increase the sound quality in an area coverage? So one big benefit is that music always SOUNDS BETTER in a soundproof space.

It also won’t be overpowered by loud noises coming from the outside of the truck.

This is great for those audiophiles out there!

4. If You Have a Baby

Some people would be driving a baby around in the truck.

If you are one of them, then you would want it to be relatively quiet. You don’t want to disturb the baby with loud sounds, after all (especially during times when they are sleeping).

What is the Best Sound Deadening Material for Trucks?

You’re ready to soundproof your truck cab…but wait!

There are so many OPTIONS out there! No worries. If you are pressed on deciding what to buy, here are the best sound deadening materials and products you can buy.

Types of Sound Deadeners

There are two types of sound-deadening insulation to consider when soundproofing your truck cab.

Peel and Stick

This type is the easiest to apply because you DO NOT NEED additional adhesives to use it.

It is best for big surface areas of the truck.

Adhesives

Some insulation would require you to use a separate adhesive to apply it.

These are less common and more labor-intensive but provides MORE FLEXIBILITY to work around small corners or oddly shaped areas. They normally come with their own adhesive.

Top Brands

With the amount of brands out there, it can be overwhelming trying to choose which one. So here are a couple of our FAVORITES.

Though if you can’t afford these, other more budget-friendly ones should still do the job.

FatMat

This is a well-known brand in car soundproofing.

They have a variety of soundproofing products designed for vehicles.

If you want to get a sound deadening mat from them, consider the FatMat Self-Adhesive Sound Deadener Kit. This is great for covering all the surfaces you need.

Dynamat

Dynamat has been at the quiet game since 1989, making them an excellent choice for CLD material.

CLD material also makes great products for soundproofing your home.

You may want to go for this bulk pack for your truck. Just using Dynamat to cover all surfaces and do wonders for the noise.

Is Soundproofing Your Car WORTH IT?

It really depends on you whether it’s worth it.

Soundproofing a truck cab can be quite pricey, but maybe the peace and quiet matter more to you than the cost of materials.

There are many benefits to soundproofing a car or truck cab, but ultimately, it’s up to you to decide. Don’t worry, as we’ve listed the pros and cons to help you.

Chances are, if you’re reading this article, you should do it.

You Can’t Completely Soundproof Your Vehicle

For effective car soundproofing, you need to add A LOT of mass to a surface. But it would make the vehicle TOO HEAVY.

Furthermore, you can’t soundproof the windows. To soundproof windows, you would have to block them. And driving without windows is NOT SAFE.

So taking all of that into consideration, you can decide whether you should soundproof your vehicle.

PROS of Soundproofing a Vehicle

  • Peaceful and quiet drives
  • Better conversations
  • Better music quality
  • More privacy

CONS of Soundproofing a Vehicle

  • You don’t hear it immediately when there’s something wrong with your vehicle
  • It’s harder to hear traffic
  • You can’t completely soundproof your vehicle
  • It’s expensive
  • It is a project that requires some effort
  • It will be hotter in the car

Final Thoughts
