How To Soundproof A Room Cheaply {5 DIY ways}

What if I told you that there are feasible DIY ways on how to soundproof a room cheaply from outside noise? Might it sound impossible?

Adding furniture and natural decor to your space is one of the simplest ways to mask unwanted noise in a room and soundproof it.

Sound bounces off hard surfaces such as hard flooring or existing blank walls.

By using soft, natural fabrics or upholstery, you can absorb sound vibrations rather than having them bounce around the room.

When you consider all the potential soundproofing solutions, it’s easy to see why people are skeptical. But it’s not impossible.

I’ve always wanted to build a studio of my own.

But the cost of building the room is prohibitive for me.

So I started doing some research on ways to soundproof a room cheaply.

This article will discuss what you need to know about soundproofing a room cheaply and easily!

Before we discuss cheap ways to soundproof a room, let’s understand what soundproofing is

What is Soundproofing?

How To Soundproof A Room

This is a process of reducing external noise in your home or office. And it is ideal for people who live in places where there is much noise.

There are various ways of soundproofing your home; you need to assess the type of noise you need to block and the materials required.

For instance, you will need less soundproofing if you are looking to block out the sound trees ruffling in the night than blocking traffic noise.

When you soundproof a room, you need to follow the rules that air can’t penetrate, and sound can’t get through.

And it would be best if you worked on minimizing vibrations as much as you could.

Four Basic Principles for Soundproofing a Room

How to soundproof a room will depend on first knowing the four basic principles of soundproofing a room from outside noise.

For example, you may want to soundproof a room from outside noise if your bedroom is next to a busy road or train track.

Or perhaps you have a home office that you need to soundproof for security reasons.

These include:

Airtight and dense walls

If you are looking to block noise from getting into your house, you’d better thicken the walls with dense and heavy materials.

This is because it’s hard to move a heavy object; thus, adding an extra layer of mass onto walls helps in soundproofing your room.

You can do it yourself by adding a cupboard or a bookshelf and lining it with voluminous books. Alternatively, you can buy soundproofing materials or insulate your walls.

Sealing and increasing the mass of the wall

Sealing all gaps in your room blocks external noise from getting into your room.

Therefore, ensure that you seal any cracks in your windows, doors, and walls to make your soundproofing project successful.

Sound travels by air, so any gap that can let in the air can allow noise penetration. Make sure that you’ve sealed all holes and cracks, especially in your windows and doors.


Decoupling is the process of separating different surfaces, such that walls, ceiling, and floors are not in touch with anything that allows vibrations to pass through.

Most people tend to use resilient channels as they use up the sound energy allowing minimal sound to make it to the walls or ceiling.

Decoupling walls helps prevent vibration from moving from one room to the next, and that’s why many people use drywall and wooden studs to avoid vibrations from traveling from one room to the next.

Using soft materials to absorb the noise

After soundproofing and ensuring that no outside noise can get into your room, the next step is dealing with the noise inside the room.

Since sound waves bounce off the walls, you must line your room and ceiling with absorbent materials so that they can absorb the noise.

Soft and absorbent materials trap the sound waves, making them lose energy.

Some of the most famous soft, porous materials for lining your room include acoustic foam and fabric soundproofing panels.

You can also use paintings, tapestries, and other fabric materials.

Investing in noise cancellation systems

You can buy noise cancellation systems such as the ANC (active noise cancellation).

They are considered to be high-tech soundproofing solutions.

The device works by producing its noise opposite to the one coming into the room, and as a result, the two cancel out each other resulting in a quiet room.

This technology is pretty expensive and is best suited for noise coming from home appliances in your house.

However, the device has a challenge canceling out noise from outside.

Factors to Look Out for When Soundproofing Your Room

Soundproofing your room isn’t as complicated as people make it.

This is because you can soundproof your space by rearranging the furniture.

However, you should be aware of what to look for when assessing your home before soundproofing.

Some of the things to watch out for include:

  • The source of the noise or sound: Once you know the type of noise you are dealing with, you’ll be better equipped to deal with it.
  • Where it is getting in from: Once you know the entry point, you will know whether to add an extra wall mass, seal the gaps and cracks or decouple your room.
  • The reflection: If it is reflected after noise penetration in your room, you’d better consider soundproofing techniques where you soundproof your headboard and footboard walls.

Therefore, filling your space with furniture helps block the noise.

Some of the furniture that will help you soundproof the room include bookcases, tables, sofas, and wardrobes.

Most people living in urban areas, especially in apartments, take soundproofing very seriously.

Most prioritize soundproofing the walls and floorboards.

It cannot be enjoyable for light sleepers.

To deal with it, consider covering every inch of your floor with heavy rugs and carpets that are cost-friendly.

The heavier the rugs and carpets, the more effective it is at reducing and absorbing the sound.

You can use rugs if you live in a rented apartment, but installing a carpet is much better if it’s your own house.

The benefit of this is that they are cheap and are designed to mold themselves into the gap.

Alternatively, you can use metal or rubber seals, and apart from providing mass, they also absorb the noise.

When shopping for door seals, consider the following:

  • Will the seal fill the gap?
  • Will the door function normally?

Cracks in the walls and windows are another source of noise pollution.

Although they are made of chemicals, ensure that they do not affect the surface they contact.

Choose a sealant that can be painted to avoid altering your room’s aesthetics.

Not only does acoustic sealant prevent noise entry, but it also helps dampen sound waves and add mass, thus improving soundproofing.

5.    Cost-friendly soundproof curtains

Curtains are great for keeping peeping toms outside.

Similarly, they can be used for soundproofing as they dampen the sounds.

So make sure to hang thick and densely woven curtains to help absorb external noise.

They are also effective in blocking out the light.

To get the most out of your curtains, get ones that are bigger than your window.

Also, ensure that the rods are positioned a few inches above the window and have a larger frame. Ensure that the curtain is long to cover the bottom and more comprehensive to cover the sides.

The extra curtain fabric helps trap noise from the outside from entering through the window, and the rods will prevent the material from reflecting sound waves.

Instead, it diffuses and absorbs it.

Soundproof curtains have different shades on the inside and outside, and most often, the outer part is dark.
