How to Soundproof a Room Without Damaging Walls

A room should be quiet and peaceful regardless of the hustle and bustle of the environment. However, this is becoming a challenge as the world gets busier and noisier every day.

Whether you’re trying to sleep or complete some tasks in your home or office, you may need a quiet environment. This is where soundproofing a room comes in.

Soundproofing your room has some notable plenty advantages. The noise remains within your doors but doesn’t get into the soundproofed room to distract you.

The best part concerning it is that you soundproof a room without damaging or tearing down your walls.

If you are looking for efficient ways to soundproof your room without damaging the walls, you’ve landed on the right page.

Here are the best ways to soundproof a room without damaging walls:

  1. Build Another Wall in Front of the Existing One

If you got space, one of the most effective ways to soundproof a room is by building a new wall in front of the existing one.  The two walls should not be attached to avoid transferring sounds from the original wall.

The new wall should be attached to the floor and the ceiling rather than the original wall.

When you put up another wall, there is an increase in the mass of the walls. Mass is an essential aspect of soundproofing as sound is transmitted through vibrations.

When there is a collision between the sound wave and the wall, there must be sound transfer.

In this case, there is no medium to transfer the sound as it cannot be transferred through thicker walls. Having soundproofed the room effectively, the original walls remain undamaged, which gives this method an upper hand.

  1. Seal the Gaps

Sound waves pass all possible openings, such as the gaps on the walls. Even the smallest gap on the wall is enough to transfer a large amount of sound. You need to seal the gaps and cracks for the effective blocking of sound waves.

You can use acoustic caulk to seal the gaps, cracks, and holes on the walls. You can also seal the open spaces around the outlet and switches. There is simple wall insulation gasket foam that is purposely made to fit around the outlets and switches.

Once you seal the gaps and cracks, your walls will be more air-repellant, which will deter the sound waves from passing through the walls.

This method will help in noise-canceling in a room and help maintain a good state of the wall rather than damage it.

  1. Add Blow-In Insulation

You can decide to use blow-in insulation, which is loose, low-density cellulose and is usually made from recycled newsprint.

This method is one of the most effective and quick ways of soundproofing a room without tearing down the walls. You can add it to the walls immediately after the construction of the room.

When you add blow-in insulation into the wall, it increases the effectiveness of sound absorption. The cellulose traps the sound waves, and their energy drained, weakening the sound before reaching the other end.

Unlike other forms of insulation, blown-in cellulose insulation also fills all the little nooks and holes, which could be the entry of noise. This method is also a cost-effective way of soundproofing your room.

Blow-in insulation is available in varieties. Depending on your preference, you can get it in loose, wet, and with high density in packs.

Here’s how to install Blow-in insulation:

  1. Hanging Soundproof Blankets Against the Wall

The use of soundproof blankets is one of the most common methods you will encounter in the soundproofing industry.

Soundproofing blankets are used to block noise from outside and block those from outside from hearing you.

When buying these blankets, you should get the ones with grommets to avoid damaging the wall while installing them. Grommets are tiny eyelets that help one hang the blankets on the wall.

These blankets are not only limited to effective soundproofing but are also excellent thermal insulators. They help in increasing the room temperature and prevents energy from leaking.

They are usually thick and act as a second layer of your wall. The second layer keeps your room quiet and free of cold.

Therefore, when choosing the best soundproof blankets for your walls, you should consider buying the thickest to ensure effectiveness.

Soundproof blankets are available in various designs and colors. You can come across those with flowers on them and minor details which fit your room’s décor.

You don’t have to be scared of what effects the blankets will have on your room décor as you can improve your room’s look by buying what suits your home.

  1. Install Acoustic Foam Panels

You can also install acoustic foam panels that significantly absorb sound waves in any room.

Acoustic foam panels are designed to weaken the degree of sound that travels through your walls. They are also favorable as they improve sound transmission in the room installed.

These soundproofing materials are capable of absorbing sound waves and transforming them into heat. This means that you can use them as thermal insulators as well.

You can get acoustic foam panels in different shapes, forms, sizes, and colors. These give you a choice of selecting the best that fits your room décor.

You can improve the panels’ visual appeal by hanging them in different positions, like alternating patterns.

When it comes to application, you can apply green glue on the back of panels and stick them on the wall. But you’ll need to be very careful to avoid damaging the wall.

  1. Apply Acoustical Wallpaper

The use of acoustic wallpaper has gained popularity these days. This method creates no damage on the wall as it’s simple to install and favorable in terms of cost.

You can opt for this method as it’s visually appealing, which means it can easily fit in the décor of any room. You’re likely to get these wallpapers in different sizes and colors.

Acoustic wallpapers are not made from paper-like standard wallpaper. It’s constructed in two different layers, whereby the top layer is made of regular wallpaper.

The underneath layer is usually made with latex or various acoustic materials. Multiple thin layers improve sound dampening, making the wallpaper more effective.

Hanging wallpapers on the wall does not damage the wall and help eliminate the room’s sound and not from outside.

  1. Place Furniture Against the Wall

Any space in your room provides an avenue for sound waves to jump around and propel energy, making them seem louder than they actually are.

Using furniture and other items available in your home, you should be able to make a change to the sound waves coming from your walls.

You can place your largest, hardest, and heaviest furniture around the wall of your room. These large items will effectively stop the incoming sound waves and eventually deter them from reaching inside the room.

When placing the furniture around the wall, you should be careful to avoid them coming into contact with the wall.

This prevents vibrations from quickly transferring from the wall to the furniture, which may amplify the sound waves. You also don’t want to damage your wall’s painting.

If you have large and hard furniture placed in the room, you can use softer furniture to absorb the waves that make it to the room.

Anything soft you add to the room helps in reducing the noise.  These soft materials can be couches, curtains, dolls, pillows, amongst others.

  1. Paint the Walls with Soundproofing Paint

You might be wondering how soundproofing paint works. Its true soundproofing paint works, but it depends on the frequency of the sound.

It’s one of the most favorable soundproofing methods when dealing with low and medium frequencies, and you don’t want to tear the walls.

The paint is usually thick and has proved to be most effective when applied several times, resulting in several layers.

You can easily apply the paint as there are no trained skills that are required. The paint is not much different from traditional paint as it can serve as décor.

The only evident difference is its soundproofing capabilities. Therefore, your soundproof paint cannot damage the wall but somewhat improves it.

  1. Place Wall Tiles Acoustic

Placing wall tiles acoustic is one of the easiest soundproofing ways that you can use to sound dampen your room.

This method is cost-effective and does not only serve in soundproofing by reducing echo and sounds but has insulating power. This means you can use it for thermal insulation in the room.

Acoustic wall tiles are odorless and lightweight, which makes them an ideal solution to soundproof thick walls. Their size is also small, which facilitates its mounting on the wall.

These tiles come with everything you require to mount them, and they have adhesive on the backside for easy installation. The adhesive glue facilitates installing the tiles without damaging the wall.

  1. Add Mass-Loaded Vinyl

Mass-loaded vinyl (MLV) is a material used to soundproof and comes in thinly rolled sheets. It consists of metal particles to achieve a greater density that makes it effective in soundproofing.

Mass-loaded vinyl can be installed on the wall using adhesive glue, which helps it sticking on the wall without tearing the wall. You should avoid nailing it on the wall as it will damage the wall.

When you install mass-loaded vinyl, there is an addition of mass on the existing wall. This ensures maximum soundproofing as there is the creation of another layer that improves transmission loss.

The mass increased creates a reliable sound blocking for your room. You can also use MLV as a thermal insulator.

When installing the mass-loaded vinyl, ensure that you cut them tightly around the outlets and switches.

  1. Put up Soundproof Curtains

Another efficient way to soundproof a room without damaging walls is using soundproof curtains.

Soundproof curtains offer a lovely and pleasing way to deal with noise in your room without damaging anything. They are cost-effective, reliable, and are very easy to hang.

  1. Cover Walls with Sound Absorbing Fabrics

You can also cover your wall with sound-absorbing fabrics to block noise without damaging the wall. You can mount these fabrics on a track system along the wall.

Sound absorbing fabrics are usually up to 100 yards without a joint. When mounted on the wall, you can have a jointless wall covered by a beautiful acoustic fabric.

Sound absorbing fabrics are offered in various colors and print patterns, which gives you options according to your personality and room décor.

  1. Become Creative with Furnishings

When your room has more space, sound waves have an opportunity to move around and within. The more the waves move around your room, the more noise they produce. The walls amplify the noise and become louder than it is.

To limit the space of sound waves, you have to become a little bit creative with your furnishings. For instance;

You can place tall bookcases and dressers along the wall and hang paintings on the wall. You can also put house plants alongside the wall and other decorative materials you got in the room.

These will help to block the space where sound waves move around and stop them from bouncing back in the room.

This method ensures that your wall is not damaged in any way, and at the same time, you will have achieved soundproofing in the room.
