Soundproofing a room sounds like an intimidating job, only to be left to professionals. However, you can do it yourself easily and cheaply. You can use different approaches when figuring out how to soundproof a room cheaply. You need to know everything to keep noise pollution at bay successfully.
Fun fact: It is impossible to survive in the world's quietest room for a long time because you will go crazy. It's too soundproofed; some people heard blood flowing in their veins.
Identify the Source of the Noise

Before I decide to soundproof a room, I must know where the sound comes from. This way, I can target the source of sound waves and use the cheapest methods to mitigate the situation. This is better than soundproofing the whole house or your entire bedroom to keep the sound out.
So, how do the sound waves travel in or out of the room?
How Does Sound Enter or Leave a Room?
How Sound Travels
Sound is a form of energy. For energy to be transferred, it needs a medium to travel through. Sound waves can travel through solids, liquids, and air. Additionally, they travel fastest in solids and slowest in air. This information is helpful when choosing which soundproofing option to use.
There are two types of sound pollution; impact noise pollution and airborne noise. First, we define sound as a waveform that has a wavelength and transmits energy.
Impact Noise Pollution
When sound hits a surface, we end up with impact noise. You can identify impact noise by touching the wall to feel sound vibrations.
Airborne Noise Pollution
When sound waves travel through the air, and you hear it, this is airborne noise. This can be sound from the radio or noise outside.
What Is Soundproofing?

A bulletproof material prevents a bullet from going through. Similarly, soundproofed surfaces block sound waves and prevent them from passing through.
We create soundproofed spaces through acoustic treatment, which is the process of improving the acoustic quality of a room. While undertaking acoustic treatment, we can either use insulation or absorption.
Sound absorption works by converting sound waves into heat and other forms of energy. Absorptive materials function the same way wave breakers do on some beaches. They dissipate and reduce the wave energy of the sound vibrations.
On the other hand, sound insulation prevents sound from passing through.
If noise pollution comes from inside the house, it is better to use solutions that absorb sound. On the other hand, if the noise pollution comes from outside, it is better to use sound insulation.
1) Interior Sources of Sound

Sound from within the space you are in can be a distraction too. Most of the time, we assume that noise coming from outside is the only form of noise pollution. However, here are some interior sources of noise that you may want to watch out for.
- Machines and appliances like the blender or the washing machine
- Kids playing in another room in the house
- Media equipment like the radio or the tv
- Gaming room, etc.
2) Exterior Sources of Sound

External noise is the hardest to deal with because there is hardly any way of controlling it. Most of the time, adjustments must be made to minimize sound pollution entering the house. Here are some external noise sources.
- Traffic noise
- Children playing outside
- Businesses
- Noisy neighbors
- Wind
- Aeroplanes etc.
Come up With a Soundproofing Plan

Once we have established a noise disturbance we must deal with; it is time to devise a plan. The first thing to do is make a diagnosis. Next, there are two important questions to ask.
i) Where Is the Sound Entering from?
While it can be clear where the sound is coming from, the path it uses to enter the house is never too obvious. You need to diagnose how the sound is getting into the space. The sound could pass through the window frame or the door if it is interior and airborne.

In some cases, noisy neighbors' sounds might be airborne and impact. For instance, when the music is so loud, the low-frequency sounds might cause vibrations to walls, while the mid frequencies will cause airborne noise pollution.
ii) Is It Being Reflected?
Like light reflection on a mirror or a bright surface, sound can be reflected when it bounces on flat and hard surfaces. However, unlike light, the sound is further diffracted, which can bend around corners. This makes sound reflection difficult to deal with and is why you need sound-absorbing materials when undertaking acoustic treatment.

When soundproofing, the main focus should be on three major areas; floors, ceilings, and walls.
Soundproofing Floors

The floor reflects a lot of sounds and can leak them to downstairs neighbors. There are different ways of soundproofing the floor effectively. Here are some effective ways.
a) Rugs, Carpets, and Rug Underlays
When soundproofing the floor cheaply, it is better to use day-to-day solutions. Typically, the best way is to get heavy rugs and carpets. Carpets absorb sound waves well because they cover a large house surface.

Interlocking floor tiles will get the job done. First, however, we have to be mindful of the materials the tiles are made of. Foam tiles look just like normal tiles and look good when used in the room. Plus, they will dampen sound properly compared to normal ones.

Cons:
Windows
Image Source: majesticglass.com.au
Windows are the first suspects when it comes to noise pollution. So the first thing to keep the noise at bay is to use heavy, soundproof curtains. Ideally, the curtains should touch the floor to ensure efficient soundproofing.
On the other hand, blinds work fine and can be a smart option while keeping the sound out. The advantage of using soundproof curtains or blinds is that they can be replaced and moved anytime. However, you can learn other ways of soundproofing windows that are more permanent.

Weatherstripping Doors and Windows
Image Source: hgtv.com
Weatherstripping is sealing any openings that may lead to air or water leaks. These spaces can include the tiny cracks that doors and windows leave along the frames. Plus, this practice can seal any cracks that sound might bleed through.
You can weatherstrip using different materials, including:
- TPE
- EPDM
- TPO filler blend
Cheap soundproofing foam strips can work when weatherstripping. The disadvantage is that the foam strips wear out quickly.

Adhesives are easy to work with because the application is like that of super glue. This makes the 3M weatherstrip adhesive a convenient choice to use when soundproofing because the application is simple. The weatherstrip adhesive works for doors, windows, and cars when keeping sound out.
Pros:
Cons:
Walls
Walls lead to most of the sound pollution in a room because they reflect the sound already coming into the house. If the walls are properly soundproofed, the sound coming in will be dead on arrival. There are foolproof ways of soundproofing walls, and here are some.
a) Soundproof Wallpaper and Mass Loaded Vinyl
Soundproof wallpaper will reduce noise easily because walls are vertical and create a barrier which sound eventually comes into contact with. Plus, the right choice can add to the aesthetics.
Mass-loaded vinyl is a great alternative to use instead of wallpaper. The vinyl is good enough to use in a music studio or a movie theatre. The material is flexible and easy to install.
1) XINOBO Texture Wallpaper

Pros:
Cons:
b) Acoustic Foam/Acoustic Panels
Acoustic panels are probably the most common soundproofing solutions around. You will see these acoustic foam tiles in recording studios mostly. The foams not only absorb noise, but they scatter unwanted sounds, making the room even quieter.

Pros:
Cons:
c) Sound Deadening Paint
Image Source: forbes.com
Sound-deadening paint will absorb noise coming into the house to a degree. I would not say the paint is the greatest soundproofing solution on the market. Plus, it will stop the sound from bouncing around the walls to disturb the room. However, you are not getting a completely soundproof house.

This paint is ideal for use in spaces where acoustic treatment, such as churches and offices, should not be obvious. The paint is discreet, and that is why I love it.
Pros:
Cons:
d) Blankets
Image Source: acousticalsolutions.com
Sound blankets are a great choice if you use your house for creative purposes involving sound. The sound blankets can cut down on noise to a great degree. The biggest advantage is how flexible the blankets are. As a result, you can use them as a sound booth, which other soundproofing solutions can not do. Plus, the blankets are portable too.

e) Acoustic Caulk for Cracks

Cracks and wall gaps are notorious for letting in unwanted sound. While sound absorption is a great way to keep sound at bay, locking sound out is an option. Acoustic caulk and spray form will prevent sound leakage and entrance, keeping your space private and quiet simultaneously.

Soundproofing the Door
Image Source: vufold.co.uk
The door is one of the biggest weaknesses in keeping sound outside. After all, it has space all around it. However, there are more than 25 foolproof ways of soundproofing doors, and here are some cheap options.
a) Door Sweep
Image Source: ubuy.ke
Door sweeps are very convenient. You do not have to make any major changes to the door if none at all. In addition, the sweep will block noise efficiently because it is beneath the door where the most sound comes through, especially the low frequencies.
1) Holikme Door Sweep

Holikme has the best solution to sound escaping into the house underneath the door. The sweep has two layers which do a great job keeping sound out. In addition, this sweep might be one of the easiest sound acoustics to install because you only need to slide it underneath the door.
Pros:
Cons:
b) Door Upgrade
Image Source: acousticalsurfaces.com
When converting your room into a studio, or when you get new noisy kids or neighbors, you can change the door entirely. You can replace it with a thicker option with space between the front and back panels. In addition, you can put soft materials between the panels to make the door soundproof. This solution can be costly and difficult to achieve, but it is surely one of the best.
What Can You Do Instead of Soundproofing a Room
1) White Noise
White noise is a consistent noise in a given frequency range synonymous with that of a radio that has lost its frequency. It sounds something like "ssshhhhhh."
Image Source: Tubefilter.com
When you have tinnitus, one of the remedies is to listen to loud music to drown the noise you hear in your ears. This same approach can be taken when dealing with external noise. For example, white noise sound machines give out the sound of rain and other white noises. You can further regulate how much noise you want to hear.
You can use white noise machines in the shower and other places. Drowning external noise is a great solution which was my first step to getting rid of external noise. You can get the best white noise machine for your office to boost privacy and focus.
2) Rearrange Furniture/ Noise Reducing Furniture
Image Source: housebeautiful.com
An empty room will reverberate sound more than a fuller one. Empty walls will do the same once you have identified that sound comes from a particular point and behaves in a certain manner. For example, you can place a bookshelf right opposite the music system. Likewise, you can move the couches near the wall.
You can intentionally make your furniture manage the noise levels by changing the upholstery to soft materials. Also, having throws on seats reduces the noise tremendously.
Factors to Consider When Soundproofing a Room Cheaply
1) What is the most prominent source of the noise?
Image Source: todaysparent.com
It would be pointless to soundproof your house if you never knew where the sound came from. Unfortunately, it is rare that sound comes from only one spot. Therefore, you must decide the specific sound you want to do away with most.
Knowing the point where sound enters the house will inform the soundproofing method to be used.
2) How Is it Entering/Leaving the Room?
Is the noise pollution airborne or impact noise? For example, if the noise enters the house through the door, how should you mitigate the situation?
Most of the time, we only soundproof when experiencing disturbances. However, sometimes we cause noise by practicing the drums in the middle of the night. One factor you must consider is ensuring your sound does not leave the house. The advantage of soundproofing is that once you soundproof for incoming sound, the outgoing sound will be taken care of.
3) Cost of Buying Sound Reduction Products: Are there Alternatives?
One free way of reducing noise can be having a conversation with a noisy neighbor to play music softly, and maybe they could understand. This way, you never have to touch the existing wall.
Image Source: elledecor.com
Otherwise, you can use everyday items like egg boxes, heavy blankets to block noise, old mattresses, and many more. Your first home studio will probably have soundproof blankets on the entire wall before you upgrade to professional acoustic foam tiles.
4) Does Installation Require Professional Help
Image Source: housebeautiful.com
When it comes to installations like changing the whole door, you must get professional help. However, sliding a door sweep underneath the door or sticking egg cartons on the wall should be a fun thing you can do by yourself or with your partner.
Conclusion
Noise can be one of the most disturbing things when in the house. However, you do not have to use expensive solutions to have a quiet room because there are many cheap soundproofing options. We discuss them extensively.
