Best materials for soundproofing a room and walls
The best soundproofing option for walls and rooms without spending a huge amount of money is just to add mass to the walls, in the form of foam panels and blankets.
This is by far the cheapest and fastest way of soundproofing a room, and anyone can do it!
In general, there are a few types of soundproofing materials you can choose from for example:
- Foam panel type products (listed below) these are sometimes adhesive large foam panels you attach to surfaces
- Sound insulation bats: Wooden or sometimes plastic batons of material you can put in corners of rooms
- Architectural soundproofing materials: This includes things that are done to change the structure or makeup of the house or room, like changing the walls or adding insulation inside the walls themselves (These materials are almost always more expensive)
- Acoustic coatings and sprays: These are the more modern soundproofing solutions and are essentially spray on coats of rubber usually, and can be a very effective cheap soundproofing solution for a lot of rooms
Here are the best soundproofing materials in no particular order.
You can also find links for places you can buy these things as well.
If you’re looking for something else, you might find our list of the best sound DEADENING materials more useful.
It explains the difference between the two.
Soundproofing foam or acoustic foam is one of the most popular items used for soundproofing walls.
These foam panels not only block out some level of sound but also improve the sound quality in a room.
Most of these panels are made from polyurethane.
Polyurethane is one of the best materials out there to reduce background noise and acoustic interference
Soundproofing foam or acoustic foam usually comes in various sizes, shapes, patterns and designs.
It is believed that the patterns on these foam panels can make a big difference depending on your soundproofing needs.
Some of the most common patterns are pyramids, wedges, mazes, waves, egg cartons, etc.
For easy installation, read this guide on how to hang acoustic foam without damaging walls.
- NRC: 0.95
- Material: Polyurethane
- Dimensions: 12“x12“x0.4″
Bubos Soundproofing panels are some of the densest soundproof panels on the market with 230kg/m3 density.
Density is the factor that determines the strength of a sound barrier.
These Bubos panels are made from high-density and eco-friendly polyester fiber sound deadening material.
They are flame retardant, odorless and non-toxic so they are safe to use in your home and around children and pets.
Bubos panels come with an NRC rating of 0.95 which puts it among the best soundproofing foam panels you can find.
They are great for reducing and absorbing noise.
Installation is quick, easy and does not require the use of any special tools or materials.
Thanks to their lightweight and bendable nature, they are easy to shape and cut to size.
All you need to attach the panels to the wall are nails, spray adhesive or 3M double-sided tape.
They can stay securely attached to a wide variety of surfaces so you can use them in almost every room in your home.
Bubos soundproof wall panels are also corrosion and fade-resistant.
- NRC: 0.90
- Material: Polyester fiber
- Dimensions: 2″ X 12″ X 12”
The A2S acoustic panels are one of the best when it comes to durability and quality.
Place them on walls, doors, windows, ceilings, floors and other areas in your home, studio or office to improve the acoustics.
These high-quality 2-inch thick sound foams feature a professional studio equipment technology design that allows them to have an NRC rating of 0.90.
They can mitigate SLAP, flutter echoes, waves and reverb to improve the acoustics in a room.
Best of all, they are SGS certified and rated Grade B on the fireproof scale.
This means that these panels will not fuel a fire but may help to reduce its intensity.
A2S acoustic panels come with adhesive stickers for installation.
All you need to do is apply the stickers to the back of each panel and place them wherever you want.
Do keep in mind that the adhesive stickers are best suited for use on smooth surfaces.
Try to avoid using them on rough surfaces as they may not keep the panel securely in place.
Another type of product that can be used for soundproofing is soundproofing blankets.
Before soundproofing blankets, there were moving and packing blankets.
These products are similar in how they tackle sound.
Moving blankets have been used for many years for soundproofing.
This is because these products are thick, dense and heavy which makes it hard for sound waves to pass.
One of the biggest differences between moving blankets and soundproofing ones is that soundproofing blankets may come with grommets along the edges.
It all comes down to personal preference so you could either choose a moving blanket or a soundproofing blanket for your soundproofing project.
- Material: cotton batting with polyester binding
- Weight: 2 ¾ pounds
- Dimensions: 21.3 x 17.9 x 16.8 inches
The Sure-Max Soundproof Blankets are moving and packing blankets.
However, due to their thickness and size, they can be used for soundproofing.
These blankets are made with thick cotton batting and polyester binding
The thickness of these blankets helps with sound dampening since sounds have to travel through them before reaching your ear.
Suremax Blankets come in a pack of 12 so it should be enough for a small room or wall.
- Material: polyester
- Weight: 8 pounds
- Dimensions: 78″L x 72″W
The Boxer Tools Industrial Blanket is a multi-purpose blanket that helps to dampen noise and vibrations.
It has a metal grommet every nine inches on one side.
This way you can hang it easily if you wish.
If not, you can use them on walls or floors.
While they may not be the most attractive-looking blankets, they are quite efficient.
This blanket is made from industrial strength polyester and the filler material is a combination of polyester and cotton.
It is also double stitched so it will stand up to normal wear and tear better than other blankets.
Sound Absorbing Panels
Some people don’t like the LOOK of the spiked and pointed foam panels we listed above. The reason the foam panels above are spiked is to better absorb the sound because the sound gets ‘trapped’ in between the foam wedges (They’re not just spiked for no reason).
Sound absorbing panels are almost as effective. A sound-absorbing panel that’s flat will still absorb WAY more sound than no foam panel at all!
- NRC: 1.0 out of 1
- Material: 100% jute
- Dimensions: 24x48x2 inches
The ATS Acoustics Panel is great for controlling unwanted reverb and echo.
They have a superior NRC rating of 1.0 out of 1.
When sounds are absorbed by this panel, they are trapped forever.
100% jute covers the solid internal wooden frame and gives the panel a pleasing aesthetic to match almost any decor.
This ATS Acoustic panel will reduce reflections from the hard surfaces in a room.
It is 2-inch thick which is great for sound dampening projects.
Resilient channels are used to decouple your drywall from the internal structures of buildings.
They improve the soundproofing abilities of walls and ceilings.
If you want to add them to existing walls, you’ll need to strip the drywall and replace it with a new one.
The best time to use them is if you haven’t put up your finishing layer of drywall on your walls or ceilings.
After you add your soundproof insulation in the wooden grid inside your walls, you’ll need to screw the channels into the studs.
Usually, you screw them to the studs perpendicular to their direction but if you’re installing them on walls, then you’ll need to place them horizontally.
This way when you install your drywall, the screws will pass through the channels instead of the studs.
Installing resilient channels can be a bit tricky so if you’re aren’t sure about doing it yourself, hire a professional.
- Material: Steel
- Weight: 1.1 pounds
- Dimensions: 96 x 2.38 x 0.5 inches
The Auralex RC8 Resilient Channel helps to reduce sound transmission.
It is made from 25 gauge steel and designed for durability.
This particular channel is used to hang drywall instead of attaching it to studs.
It should be installed horizontally at the bottom of walls with at least 2 inches or less in between.
You can hang up to 2 layers of 5/8” drywall as well as a layer of Auralex SheetBlok on the RC8.
It creates a ½” air pocket between the layers.
This mechanical decoupling will improve the STC rating of any wall or ceiling.
The RC8 comes with 24 8” pieces per box which are more than enough for one wall in a small room.
Acoustic caulk can be used for sound dampening while sealants can be used when adding the finishing touches to your wall.
Acoustic caulk can also be used between layers of drywall or plywood to increase their STC ratings.
Acoustic caulk and sealants can both seal off or plug the space where air can pass through.
If air can pass so can sounds.
They can also be used for sealing cracks and gaps around doors and windows.
Check out more in the best acoustic caulk review guide.
- STC Rating: 56 in a drywall/single stud wall

Auralex Acoustics acoustical sealant is a water-based sealant that can reduce sound transmission.
It can be used on walls, ceilings and floors.
When used correctly, it can achieve an STC rating of 53.
It comes in a 29 oz caulking tube which means you’ll need a larger than normal-sized caulking gun for applying the caulk where you need it.
If you have an open-plan house, then soundproof room divider curtains are a great solution.
It can be useful if your bedroom isn’t separated by a wall from other areas of the house.
These room divider curtains come in all different styles and sizes with grommets along the top edge.
You would need to set up a ceiling rod to install them.

It can be used almost anywhere in the office where you need a private and quiet space.
The most successful soundproofing projects start from within.
During construction, you should include some type of insulation inside the wall and ceilings.
While the primary purpose of insulation is to prevent air from seeping through surfaces, it also helps with soundproofing.
Insulation also adds mass and absorbing properties to your walls.
- Material: Fiberglass
- R-value: 4.7
- Length: 25 ft
This fiberglass insulation works great under floors and in between walls.
It has an R-value of 4.2 which means that it can resist heat flow.

Installation follows the same instructions as other foam panels.
Soundproof drywall or fake wall – Best for creating fake walls
Adding drywall on top of an existing wall can be very effective in your soundproofing process.
There are five types of drywall according to their purpose.
This type of drywall is the cheapest you can find.
However, it is not the best when it comes to soundproofing.
If you do choose to use this, stuff the inner layer between the existing wall and drywall with some soundproofing insulation and place acoustic panels on the outside of the drywall.
Mold resistant drywall
If you’re soundproofing a room with lots of steam like your kitchen, this type of drywall is best.
Moisture resistant drywall
As the name suggests, moisture-resistant drywall is best for rooms where water can come into contact with the drywall.
The bathroom is a great place to use these.
This type of drywall will not prevent a fire but it can buy you a bit of time in the event of one.
It is the best choice to use in garages and stairwells.
Soundproof drywall has a higher transmission class than the other types.
However, its effectiveness depends on the soundproofing methods you implement before installing it.
This type of drywall comes in several thicknesses and thicker is always better.
There’s quite a bit of doubt when it comes to soundproof wallpaper and paint.
Some believe that soundproof paint can improve the amount of noise in a room.
However, the results aren’t promising.
You can use soundproof paint to create a soundproof barrier before adding acoustic panels and others soundproofing products to your wall.
The reason why some people believe soundproof paint works is because it contains latex.
Rubber products are often the go-to for soundproofing around the house.
Latex, like acoustic caulk, settles into tiny cracks and gaps in the wall and maybe that’s why there is a slight reduction in sound transmission.
- Material: Water-based
- Application: brush, roller or hopper spray gun
- Size: 5 gallon
This sound-deadening paint helps to dampen ringing, echo and tinning noise in a room.
This is because it is a heavy-bodied, water-based flat latex paint with ceramic microspheres and sound-absorbing fillers.
This helps it to reduce sound transmission and provides insulating benefits as well.
This soundproof paint is environmentally friendly and non-toxic so it can be used anywhere in the home.
Application is easy and all you need is a brush, roller or hopper spray gun.
In the event of any spills, simply clean with just soap and water.
Soundproof wallpaper like soundproof paint has some effect but not very much.
However, people still use them since they do have some soundproofing properties.
These products are usually made from closed cell polyethylene foam which has some sound-absorbing properties.
Soundproof wallpaper is essentially very thin acoustic panels.
While they may not absorb sound as well as acoustic panels, they get extra points for style since they come in various decorative designs.
- Material: PE foam
- Pack of: 11
- Covers: 64 sq. ft
These Art3d foam wallpaper can help to improve the acoustics in a room.

Best materials for soundproofing floors
Sound dampening materials are things that aim to just add mass usually to the floor to make the sound bounce off and reflect back into the room.
This gives the dampening effect that reduces the amount of sound that escapes and enters the room.
The most common types of dampening materials are mats, sprays (usually rubber) and rolls of material.
Mass loaded vinyl or MLV is great for adding mass to your walls, ceiling and floors.
It is fairly thin and flexible so it doesn’t add unnecessary bulk wherever you use it.
MLV’s primary purpose is to add mass to block out sounds completely.
It is very effective and one of the best products you can use if you hope to achieve the best soundproofing effects.

What is a soundproofing material?
If you’re wondering what soundproofing materials are, here are some basics.
In this section, we’ll talk about what soundproofing materials are, how they work and how effective they can be.
First off, you need to understand sounds before you can understand how soundproofing materials work.
Sound is a type of energy and energy is a result of things vibrating.
Once created, that energy has to go somewhere.
In the case of sounds, the energy travels away from its source and makes objects and the air around us vibrate.
The energy then reaches our ears making our eardrums vibrate and we can hear the sound.
In other words, a sound starts at its source, travels through several different media then reaches our ears.
If you want to soundproof a room or wall, etc, you will need to stop the sound somewhere along its journey.
Interrupting the chain of events from the time a sound is created to when you hear it can significantly impact the level of sound that reaches your ear.
Soundproofing is the process of reducing sound pressure from the sound source to the receptor.
This is where soundproofing materials come in.
Soundproofing materials make soundproofing possible.
Several construction materials are believed to have noise reduction characteristics.
However, you need to pick the right materials for your soundproofing project.
Every soundproofing project is different and you’ll need to choose materials based on different transmission modes and noise frequencies.
Another factor you need to take into consideration when choosing soundproofing materials is where you are going to be placing them.
Let’s take a look at some properties of soundproofing materials that can help you decide which one is right for your project.
Sound absorbing material vs soundproofing material
There is a bit of confusion when it comes to soundproofing and soundproofing materials.
One of the most common misconceptions is that sound absorption is the same as soundproofing.
Unfortunately, that is not exactly true as sound absorption is one of the many elements of soundproofing.
The difference between sound-absorbing material and soundproofing material Is simple.
Sound absorbing material is used to improve the acoustics of a room while soundproofing material prevents sound from going in or out.
Sound absorbing materials help to reduce reverberations and the echoing of sounds already present in the room.
They cannot stop a sound from entering or leaving so they may not be the best for soundproofing on their own.
However, you can use both soundproofing and sound-absorbing materials if you want complete sound isolation.
Principles of soundproofing
Soundproofing may sound complicated and that is because there is a lot of misinformation that can create confusion.
There are just four soundproofing principles when you consider the physics of sound transmission.
These principles along with the techniques and materials used for soundproofing are more than enough to make sure your project is a success.
The four basic principles of soundproofing are:
Any material that is solid, heavy and thick will block sound.
Some people are annoyed by airborne sounds like voices.
If you are one of those people then you will find that this approach is the most effective.
You can use furniture to add mass to the walls if you’re not ready to purchase any soundproofing product.
This way you can test out how adding mass to the walls can help to block sounds.
If convinced, you can then try to Mass Loaded Vinyl under or over your drywall.
Do keep in mind that adding mass isn’t effective if you’re dealing with impact noises.
Damping sounds can be achieved with damping compounds.
These damping compounds have a unique property that allows them to convert sound energy into heat.
This stops the sound in its tracks and makes it disappear.
Green Glue is a perfect example of a dampener.
Silicone caulk and even some automotive soundproofing materials have similar properties.
For best results, the damping compound needs to be applied between two stiff panels like drywall or plywood which needs to be screwed together.
This is done so that when a sound hits your panels and damping material system, it triggers shearing forces between the rigid panels and creates friction in the damping layer.
This chain of events converts sound energy to heat thereby eliminating the sound.
Damping is the best method if you’re dealing with low-frequency noise.
Decoupling is the most effective method if you find that sounds are being transmitted through the structure of a building.
Introducing gaps in certain parts of the structure make interrupting sound vibrations so much easier.
The coupling is best done during the construction phase. It is possible to do it after but it is a far more complicated scenario because you will have to remove existing walls, floors or ceilings.
Resilient channels are best for decoupling your drywall from the structure of the building.
Resilient channels are effective at dealing with low frequency and impact noise.
This is because sounds will vibrate uselessly against the channels instead of passing through the walls.
Decoupling is highly effective but it requires planning and professional installation.
If you are going to have it done be sure to take your time and hire someone who knows what they’re doing.
Decoupling done right is great but having it done poorly can worsen low-frequency noise.
The last soundproofing principle is absorption.
Absorption does play a role in soundproofing but it isn’t as effective as the other soundproofing principles.
While ineffective on its own, combining it with the other soundproofing principles will give you the best results for your soundproofing project.
You may be already familiar with some of the most absorbent soundproofing materials like acoustic foam.
acoustic foam comes in various sizes, shapes and colors.
They are best used to improve the audio quality inside of a room rather than blocking sound.
Just like acoustic foam, soft pieces of furniture can also work for sound absorption.
The four principles of soundproofing work independently but they complement each other well.
If you apply one of these soundproofing principles for your soundproofing project and are still not satisfied with the noise reduction, try applying another.
Combining one or more of these soundproofing principles will give you the best results possible.
