So, let’s jump right into it.
1. Seal Gaps and Holes
When soundproofing a wall, it is important and far easier to start with any available gaps, cracks, holes and more. Sealing gaps is not the hardest job of the day.
What you need are the right materials for the job and you will be good to go. The most common soundproofing sealant comes in the form of acoustic caulk.
Acoustic caulk is very efficient and effective at gapping any spaces or cracks that appear in walls and joints.
The sealant offers some of the best properties for doing the job. It is flexible and it doesn’t shrink.
Applying acoustic caulk on the surface is pretty easy. Here is a quick process on how to do it:
- Remove any form of dirt from the target surface for the effective application of the sealant.
- You will need a caulking gun to apply the sealant over the gaps and cracks in the wall.
- The last thing, use your fingers or a caulking tool to smooth the caulk evenly on the surface.
Note that you are working in a well-ventilated space. The acoustic caulk comes with a strong smell, which can be very irritating and potentially damaging when inhaled.

2. Set Up Some Soundproof Curtains on the Wall
It is obvious that soundproof curtains are used on windows and doors. However, these curtains can also work well when hung on walls.
Soundproof curtains are designed with acoustic properties. The design of these curtains features thicker and heavy material fabric, which are effective in absorbing and dampening sound waves.
Sound curtains do not block sound. They only reduce its impact once it gets in the room; cutting down on reverberations and echoes.
The result is reduced noise levels inside the house. Sound absorption with these curtains is five times better than using the traditional curtains normally used for aesthetic purposes.
Before you do anything, you will need to install curtain rods on the wall before you hang the curtains. Ensure that you choose long and wide enough curtains that can cover the whole area well.
While these curtains are not going to be your penultimate solution to the noise problem in your house, they help to attenuate sound waves into background noise. Let’s say they make the noise seem like coming from inside a closet.
These curtains are also known as drapes and can be doubled up or quilted to increase density for effectiveness. Soundproof curtains can be used to block out light from filtering into your space.
Installing them is pretty simple – you can do it alone.

3. Apply Weatherstrip to Cover Holes and Cracks
Another method on how to make walls soundproof includes the use of weatherstripping tape to cover existing holes in the wall. Such spaces can be located especially around the windows and door frames.
Fortunately, weatherstrip tapes are relatively inexpensive quite cheap on the market. Better yet, doing the weatherstripping is a breeze, you don’t need to have any special skill-set to undertake the project.
Before you embark on the project, carry out some tests including light tests on your window and door frame. By inspecting the door or window frame from inside in the dark, you notice whether light is leaking through or not.
If there’s light leakage, it means sound waves also use the same path to sneak inside the room. You will have to apply the weatherstrip tape and make sure you are using a strong adhesive to attach the tape.

4. Use Soundproof Blankets
Soundproof blankets, just like sound curtains, use the same principle of density and thickness to exclude sound waves.
These blankets are made using heavy materials. So, they are capable of blocking out sound when applied on the walls.
This is not the best way to soundproof a wall but the method packs a punch. First, because the blankets can eliminate a significant amount of noise at a very small price.
They are also easier to install needing no professional intervention. As long as you get those moving blankets with grommets, hanging them up is never going to be a problem.
Even more, removing them for cleaning is simple.

5. Apply Mass Loaded Vinyl
Mass loaded vinyl or MLV is an extremely effective soundproofing material. Many applications involving thwarting sound waves or noise utilize MLV.
It can be used on walls, ceiling, and doors but today we’re just focusing on walls.
MLV does its work effectively because it packs a lot of mass and density. In terms of structure and design, it is a super-thin material but make no mistake, MLV is very dense.
The rubbery material is also flexible; thus its application is not going to be a hassle at all.
The only downside of the Mass loaded vinyl is its price. The soundproof material is quite expensive in relation to other methods on this list.

6. Try Out Professional Soundproof Foam Panels
Perhaps you have heard about acoustic foam panels. They constitute a professional way of soundproofing walls.
However, acoustic panels are not sound blockers for walls. This is because they are fluffy and porous, hence they still allow sound waves to go through them.
On the contrary, acoustic foam panels only absorb sound waves. The main purpose of these materials is to absorb sound and reduce echoes and reverbs in your room.
So any noise passing through the walls is taken in by these foam panels. Then, the sound waves are converted into heat energy which is dissipated.
Acoustic foam panels come in different patterns and colors. It is up to you to choose what you think would work for the decor of your room.
You might want to call for a professional to help with the installation. Of course, if you are not a savvy in matters soundproofing.
If you are hands-on, setting up these materials on the walls is not going to take you a lot of time. It’s pretty easy.
These Mybecca 12 Pack Acoustic Panels are some of the best on the market. True to professional interior design, these foam panels can be used in homes, offices, theaters among other places.

7. Try Rearranging Furniture in Your Living Space
One question many people ask is oftentimes: what is the best way to soundproof a wall? I usually don’t have a definite answer.
Nevertheless, for effective soundproofing, combining different methods could produce excellent results than relying on one way of doing it.
With that said, the cheapest way to soundproof a wall is just by simply rearranging the furniture in your living space. In fact, you may not spend any money at all.
You can achieve this process by adding more bookshelves and closets in the living space. Add books into the bookshelves and fill clothes in the closet.
Move them closer to the wall – they will create a barrier to block excessive noise leakage into the room.
Second, they block noise pathways hence discontinuing its travel.
If you had your sofas or couches against the problem wall, ensure you move them away from the wall. Place them in the middle of the room or further away. This way, you increase the distance the noise from your neighbour has to travel.
