If you are in serious concern on how to avoid unnecessary soundwaves which we call noise then probably searching for the list of soundproofing material which can help you to overcome this issues, if so then here we are with the list of every possible best product which a person needed to soundproofing a house, room or any private space.
Due to increasing traffic, machinery and unwanted noise from a neighbor it makes annoying your peaceful life, if you are a person like me who cheers peace and quiet then probably you are at the right place, where we discuss every problem and the best affordable solution.
This guide is the best of my personal experiences and learning from various issues, I searched the affordable solution online to overcome specific issues and the results were amazing.
So if you just started or already done with the research of soundproofing material this guide will value add to your search.
In summary, here we will learn the basics of soundproofing, what things you need to fix for soundproofing issues and what are the best products for soundproofing.
What is Soundproofing vs Sound Absorbing?
People got confused with these two big terms in sound engineering, so let me clarify to you first that sound absorbing is an element of soundproofing, but how? do not worry will discuss the same in detail but before that let me explain what this sounds all about.
Sound is a sort of energy generated from any source and travels through space by creating pressure. As soundwaves or energy generated, it starts creating pressure to air particles and they start displacing in a wave pattern and the same thing continues till the end unless it got a barrier.
This soundwaves or pressure waves strikes to our eardrum and create the same pressure and later the same will be sensed by the mind and human can experience the types of sound.
But what, if there is a mixture of sounds coming together which has a low-high frequency and not easy to differentiate actual sound? That is call noise.
The only major difference between sound vs noise is, the sound is easy to reproduce however noise is not reproducible.
Well, you got a major difference, so to avoid noise there are two ways and those called soundproofing and sound-absorbing.
Sound absorbing is a way to minimize the echos and improve the sound quality where your main focus is to absorb the soundwaves and minimize the reflections from different sources.
However, soundproofing is a way to create a barrier for soundwaves transmission.
Let imagine, soundwaves are coming from the neighbor house, as we learned earlier if we put a barrier to the transmission path of soundwaves we can stop it to move forward.
Hence using soundproofing you will be able to stop getting unwanted noise, however, sound-absorbing helps you to improve the sound quality by minimizing the echos.
To learn the major differences with the detailed example I recommend to visit and learn the comprehensive guide on soundproofing vs sound-absorbing.
Hence in this guide, we will classify all the soundproofing material based on the categories they belong to such as soundproofing, insulation,sound-absorbing materials, etc.
Before deep diving on buying the soundproofing material, it is better to learn the types of material you would need for soundproofing.
Things matters in SoudProofing material
Soundproofing won’t be possible by buying a product and use it to block the soundwaves it has many more factors to consider.
If talking about the basic learning of soundproofing then make sure you aware of the below key factors which really matters while choosing the soundproofing material.
Mass or density of the Material
Soundproofing’s main idea is to create a barrier that stops further movement of soundwaves or in other words, it helps to block the soundwaves by reflecting back to the original direction.
And the ability of any material to work as a strong barrier depends on its mass or density the higher the mass it has the stronger it has the ability to create a barrier.
So make sure to research this, if your aim is to create a barrier or block the unwanted noise coming from the other side of the area. The best affordable solution for the same is to use Drywall or MLV, later will discuss in detail.
The absorption capacity of the material
Absorption helps to minimize the echos, sometimes even a low-frequency noise due to the reflection from different hard surfaces in the room cause amplify.
You probably heard the music in the bathroom and in a room, both have a different level of amplification in the sound, why? It’s because of the echos.
The best affordable solution to minimize echos is using the acoustic foams, so make sure the material you use is less reflective and have the ability to absorb or trap the soundwaves in it.
Dampening capacity of Materials
Soundwaves is a form of energy that vibrates the air particle coming on its ways, in such a way it proceeds further from one place to another.
While sound energy travels, it creates vibrations to the air molecules which pass through the next material and move forward. So dampening materials help to minimize vibrations.
Such materials dissipate the sound energy by converting them all into the heat waves. The very best example is Green glue will discuss later more in detail.
Insulation ability of the material
Insulation is another primary factor that helps in soundproofing as it provides a strong barrier for the soundwaves to pass through.
If we talk about the Drywalls, which are set on top of the verticle studs will leave a cavity between the verticle studs so the solution to fill them is using the insulating material.
Such material helps to create a strong barrier for the soundwaves coming from the other side of the wall the very best example is Batt, blow-in or Foam spray insulation materials.
Decoupling is the best concept of soundproof engineering where idea is to trap the soundwaves in between the two different environments.
Soundwaves travel faster in solid as compared to air and liquid, why? Because molecules will be closer to each other and if referring steel it is 17 times faster as compared to air.
Usually, in the USA, people use drywall to soundproof a house by placing an additional layer on the existing wall but if it is not enough then using the resilient channel you can cover another layer of the drywall.
By placing another layer will create an empty space between two walls which help to slow down the vibrations of the soundwaves coming from the first solid surface to air then again solid.
I imagine you got a good idea on how to soundproof engineering works and what factors matter for which purpose, so let me highlight all types of soundproofing material available for each category.
Top Soundproofing Material for Affordable solution
We have categorized all the materials based on its use for the above-provided purpose so it would be better to navigate to a specific section and can get an idea on the best affordable products available in the market.
Every product has a reference to buy given for Amazon, so for each product’s latest price and customer review make sure to go through the Amazon itself.
Best Sound Absorbing Material
There are thousands of ways to absorb the unwanted soundwaves which really help to minimize the reflection of the unwanted noise.
As in the house, we have strong walls, glass, or furniture which do not absorb the soundwaves but reflect them back which in result sound amplify and gets more annoying, to avoid this you can use below sound-absorbing materials.
Best Acoustic Foam
If you have heard about the best soundproofing solution in small studios or rooms is the acoustic foams which also known as sound-absorbing foam.
It absorbs the soundwaves and reduces the reflection which depends on the Noise Reduction coefficient (NRC) or the ability of the material.
If you are willing to buy then you can go with the Fomily which has a great customer review and provide 12 Pack of acoustic panel best suits for your private room or a studio.
It is available in varieties of colors and each piece is of 1 square foot and 1 inch thick for better acoustic control. It is well suited for acoustic treatment by noise reduction, reduces waves, and minimizes the echos.
Acoustic foams have been categorized into various forms based on usage, such as flat panel,egg-crate, pyramid or bass trap, etc, to learn more make sure to visit the detailed guide on is soundproofing really works?
Best SoundProof Curtains
The major source of sounds reflections in a room is from the wall or the window or door so the very best concern is the reflection from the window.
If we talk about the noise reduction coefficient (NRC) of the window then approx 95% of the soundwaves reflect back which later amplifies noise to the next level.
Using soundproof curtains you can minimize reflection up to a certain level as it not only helps in minimizing echos but helps in maintaining the heat inside the room.
The denser and more layer the curtain has, it will be more effective in sound absorption and Nicetown blackout curtain is among the most popular curtain available in the market.
It is available in two panels to cover the whole window end to end and each side is around 52″ wide and 84″ long, this is perfect for thermal insulation and energy-efficient and it’s both sides are of the same color.
Selection of SoundProof curtains could be done on various parameters if you are interested in buying soundproof curtains then make sure to visit the detailed guide on best soundproof curtains.
You have definitely heard about the moving blankets which are denser in quality and widely used by people to absorb the soundwaves but is this effective?
Moving blankets are a bit different than a soundproof blanket, but yes good enough solution for sound absorption if you do not have the soundproof blanket.
Soundproof blankets are made of two layers were the topmost layer is a transparent layer that allows soundwaves to pass through and the internal layer is dense enough to trape the soundwaves in it.
Hence you are looking for the best soundproof blanket then the well-known name is Audimute which has NRC of 0.85 which means it can absorb 85% of soundwaves and reflect back only 15%.
It is of larger size as 95″*54″ and includes three metal grommets for easy installation as it is well suited for recording studios, vocal booths or any private area due to its good quality sound absorption sheets.
Soundproof blankets are a bit expensive as compared to moving blanket so if you are looking for a detailed overview of comparison then it is better to check the detailed guide on is soundproof blankets works?
Above three are my best popular choice in case if looking for the solution on sound-absorbing or soundproofing a house, now let focus on other materials
Best Soundproof Insulation
Soundproof insulation is the very best option if you want to stop the transmission of the soundwaves. It actually works as a strong barrier.
Most of the time people having issues from their neighbors due to louder noise and weak partition in between both houses, hence the very best solution is a barrier on the way to sound transmission.
Insulations are of different types such as Batt insulation, blow-in or foam spray insulation where their job is to fill the cavity and block every corner which allows pass-through of sound waves.
Out of three, Batt insulation is one of the most affordable solutions you can have in between the vertical studs behind the drywall. It is made of fibers, mineral wools or cotton, etc.
The well-known insulation is Roxul Acoustic Mineral Wool insulation which is available in 6 pieces with each sheet size of 48″24″*2″.
This is one of the cost-effective and very high NRC ratings, water-repelling, hydrophobic and class A fire rating soundproofing material.
The above suggestion is the affordable solution which is widely used for fixing, floor, wall or ceiling cavities, to learn more about types of insulation make sure to visit the detailed guide on types of insulation.
Best Sound Dampening materials
As explained earlier the main job of soundproof materials are to dampen the energy of the soundwaves by dissipating and converting into heat energy.
Dampening materials reduce the amplitude of the noise and overall minimize the energy of the forward-moving soundwaves. Hence below are the best affordable solution.
Mass Loaded Vinyl (MLV)
MLV is the ultimate way to add the mass to the existing wall, floor or ceilings. We already learned earlier you can create a strong barrier for the soundwaves by introducing a high dense mass on the existing wall or barrier.
But the issue with any mass material is its width and weight if you look for high dense material then probably you have to bear the weight as well.
But Mass loaded vinyl is exceptional in the case which is thinner in quality but has absolute ability to block the soundwaves or reflect back soundwaves.
It is flexible in quality and easy to fold or hang on top of the walls, ceiling or any noise block out areas where it required.
The well known MLV is TMS Mass loaded Vinyl which is perfect for residential and commercial space use and of 1/8 inch of thickness and having various products covering in between 16-100 square feet in total area.
To learn more about the advantage of MLV, how it works and why this is the best affordable solution and what are MLV alternative make sure to visit the detailed guide on what is Mass loaded Vinyl?
You have heard the noise made due to vibrations in the car, home or work locations and that noise you can overcome using the noise deadening floor solutions.
Many houses are made of wooden floors or any engineering floor which may be the reason for the generation of noise such as footfall noise or noise due to chairs, furniture impact on the floor.
Even in some cases, people are getting noise from the person leaving beneath your flat.
The very best solution for such noise is sound-absorbing underlayments by Advanced acoustics which is around 3 *1.25m in size and 2mm thick, which covers the overall 100 square feet area.
It’s one layer that has an insulation value of 24dB and if two layers can help you to dampen around 29db. Its weight is around 5 kg per square meter.
You can glue this acoustic mat directly to plasterboard on the floor or stud or may create a sandwich by putting plasterboard in between two layers.
It works as a dampening material in between the impact on the floor, if sound energy got generated, it will dampen the sound waves.
In place of this, you can also use the soundproof carpet which also helps to overcome the noise generated from the floor as a soundproofing material.
Sound Deadening Paint
Well, many people argue the ability of soundproof paints even I do earlier but the logic is simple if you can coat something on top of others it adds mass to the existing surface.
In a similar way, soundproof paint claims the STC up to 3-7 point which means it could be effective if it works the way manufacturer claims.
The process will be easy to spray or coat every thin surface with paint which will create a reflective surface and help to dampen the soundwaves.
The hy-tech thermal solution is offering Acoustic coat sound deadening paint of 1 or 5 gallons which is made of sound-absorbing fillers.
Which absorbs the sounds and prevents them to bounce back where the noise reduction in the 500 Hz is by 30%. You can use this on top of the drywall, ceiling, walls or plaster wall as a soundproofing material.
Best SoundDecoupling Material
Decoupling is the best way to slow down or trap the soundwaves. As we learned earlier soundwaves can travel faster in solid as compared to air which means the closer the particles will fasten the further propagation of the soundwaves.
Decoupling is the way to interrupt the medium of soundwaves propagation where once it starts from the one layer of the Drywall will enter to the decoupling zone before the next layer of drywall and in such a way vibration will get reduce.
Green Glue NoiseProofing Sealant
Green glue is a viscoelastic component whose primary job is to dissipate the sound energy to heat energy. Its main purpose is to fill the gaps or cracks and to provide noise proofing sealant.
In addition to this, it is widely used between the two-layer of drywall to create a decoupling zone. Where while noise waves pass from the first layer will be dissipated in the decoupling zone by green glue due to viscous nature.
Green glue in the laboratory and in the field stated an STC score of 55 which is more than 50 required for efficient soundproofing.
The very best offered by is Green Glue with 6 or 12 tubes of noise proofing compound. If you want to use this in between the plasterboard or drywall then 2 tubes are good enough for 8*4 ft sheet.
Resilient channel is the best way to create decoupling in between two layers, if you want to put a layer of drywall then it’s better to use resilient channel than screwing this to the existing wall.
Resilient channel is the strip of metal with small holes in it which can be easily screwed against the verticle studs were on top of that you can screw the additional layer of drywall.
This will create a decoupling zone in between both layers of drywall and will be very effective in noise proofing your house or room.
The well-known product seller is Auralex Acoustic who provides RC8 Resilient channel in 25 Gauge metal boxes of 24-8′ lengths.
It is the best fit for drywall and reduces sound transmission as it creating a 1/2″ of an air pocket in between the layers.
You can have sound decoupling by introducing green glue in between the two drywall where the decoupling zone has been created due to resilient hence this among the popular choice of soundproofing material.
Drywall is made of the same material of plaster which we call Gypsum. It is made of fibers, plasters and foam agents.
Drywall is made by grinding the gypsum into the fine particles and then mixed with water to create a slurry that packed in between a two-layer of recycles thick paper layer.
It is the only very best option people use to add mass on the existing wall by setting up a verticle stud and covering that with Drywall. Where the back cavities are filled with insulation materials.
To learn more about how soundproof drywall works and what makes them perfect for soundproofing material it is better to check a detailed guide on what is Drywall?
The other major area from which soundwaves came through is windows, due to the single glazing layer it is not efficient enough to block the soundwaves.
So make sure to install double glazing and create a decoupling in between both layers which trap the soundwaves and in result no more transmission of the sound waves.
Make sure to have different sizes of thickness for both glazings where one should have around 6mm then others should be 4mm in thickness.

Additional Soundproofing Accessories
Above are the major soundproofing material but there are few used for the soundproofing based on their necessities, let me highlight a few of them.
Weatherstripping for Window or Door
Well, the window and Door are the major source for soundwaves to coming into the room because of the small spaces left around the corner of the window or door.
This can be overcome by setting up weatherstripping which you can push hard to the corner of the window and window frame which nowhere left any space to air come in.
In a similar way the same weatherstripping you can use to fill the joints of the door and the door frame for filling every empty space.
If willing to buy weather stripping then make sure to check out 52 feet/16 weather stripping by SAVINA for door or window which is a high-quality material used for preventing wind, dust, sound, insect and designed to reduce noise effectively.
Make sure you push it hard to every corner to avoid any leak left around the corner as if light or air can pass through that means it’s easy for soundwaves to pass through.
Acoustic Sealant for door
Well if we talk about the door which can have cracks or maybe space in between the door or the door frame, in that case, the best solution is to fill that hole which allows getting air to come through.
The best affordable solution of an efficient way is using an acoustic sealant, which enables you to fill all the small holes left around the door.
For that, you can have a Great Stuff window or door 12 oz insulating foam sealant which will be yellow in color and good enough to create an acoustic seal for the empty spaces.
Never miss such small gaps because every time while you do installations then due to joint or mismatch between frame and door it always has small cracks left. So consider this as a primary soundproofing material.
Soundproof Door Sweep
The door sweep is used under the door to cover the gap between the door and the ground which also causes a major reason for noise to come into the house.
To overcome this the best solution is to block that space using the door sweep which are of different types the one which can be easily removed while others can be fixed permanently.
For best product purchase you can go for MD Building Products 1-1/4 inch commercial grade door sweep, this is available with a 36-inch aluminum metal bar with the same length of door sweep.
It has a number of holes that help you to easily fix at the bottom of the door. It is protective against drafts, moisture, dust, and insects and can be used for commercial or residential purposes.
To learn more about types of door sweep and which one is best then make sure to visit the detailed guide on soundproof door sweep.
Well, above are the important soundproofing material required to soundproof a room or house.
My View on soundproofing material
Now every space including room, studio, and office spaces required soundproofing due to unnecessary noise distracting your peace and become the cause of reducing the efficiency in sleep and work.
Using soundproofing materials you can definitely minimize it but how much you can block this will totally depend on the materials and way you do soundproofing.
I have created multiple guides on various ways to do soundproofing a house, room, window, door and many more, make sure to visit them all.
Let our reader know your experience with soundproofing materials so they can decide or block the noise.
