How to Soundproof a Wall Between Apartments – 10 Best Ways
10 Best Ways to Soundproof a Wall Between Apartments
#1. Fill the Empty Space in the Room with Furniture and Stack them against the Wall
You might think that I am crazy for suggesting this as the first method to soundproof a wall between apartments. But trust me it works perfectly. For this method to work you need to fill the room with furniture and also make sure you need to stack them against the wall for this method to work.
The science behind this method is that usually, the walls between apartments are pretty thin, so adding furniture like Couch, Wardrobes, closets, china cabinet or any type of cabinet or Bookshelves and many other types of furniture could work. When you stack these types of furniture against the wall you make the wall more thicker and denser making it more soundproof between apartments.
One small hack to make this method more effective is that, make sure you add one more layer between the wall and the furniture. For example, add a soundproof blanket or a soundproof curtain in between the furniture and the wall. The blanket or curtain acts as a middle layer which could absorb more sound waves that are trying to pass from the furniture. Even soundproof foam or acoustic foam can work wonder you can add them as the second layer between the furniture and the wall for more effectiveness and soundproofing the wall between apartments.
#2. Use Mass Loaded Vinyl
We all know that Mass Loaded Vinyl is the best soundproofing material there is in the market, then why not use it to soundproof walls between apartments. Mass Loaded Vinyl has multiple application not only used to soundproof walls. Mass Loaded Vinyl can also be used for thermal issue also. These Mass Loaded Vinyl can act as a barrier on the wall which could tackle the outside thermal heat into entering the apartment through the wall. Mass Loaded Vinyl is more of mat kind of material which is very thick and fat and is one of the best soundproofing material ever created.
You can install mass loaded vinyl directly on the wall with the adhesive that is present behind it or you can use any type of adhesive and install the mass loaded vinyl mat on the wall. These mats are not very pleasing to look at so you need to hide it or wrap it around other stuff on the apartment so that it’s not very visible to others.
Some ways to use mass loaded vinyl in the apartment are
- Install Mass Loaded Vinyl on the wall and place furniture in front of it so that it’s not so visible to other people and also acts as an extra layer.
- Install Mass Loaded Vinyl on the wall and cover or wrap it up with curtains.

#3. Install Acoustic Foam Mats
If you are a regular reader of this blog then you would have read about times where I have mentioned about acoustic foam mats. You might not know this but acoustic foam mats are not that good soundproofing material directly, that just make the room more acoustic where the sound signals bounce off the foam mats making it more tender and acoustic. In this case, acoustic foam mats are perfect because as we had declared that apartment walls are pretty thin, so acoustic foam mats makes the sound stay within the room making the apartment wall more soundproofed indirectly or directly.

Acoustic Foams doesn’t cost a lot so it’s affordable and at the same time acoustic foam are know to soundproof the room than most of the soundproofing material that is available.

#4. Install A Layer or Two Layers of Drywall
Installing a layer or two layers of drywall will directly thicken your wall which in turn absorb or soundproof the wall between apartments. A Drywall is made up of gypsum, ceramics, and viscoelastic. But this is not my recommendation. My recommendation is two install two layers of drywall, which would increase its effectiveness and more soundproofing the apartment wall.
One disadvantage of installing drywall is that its not that easy. You definitely need a professional person to install the drywall in your apartment so make sure you hire one.
#5. Paint the Walls with Soundproofing Paint
You think this is a joke, but it’s not. Soundproofing Paint does work and there is scientific evidence for it. These Soundproofing Paint or Sound Deadening paint can reduce the sound by 50% when applied in the apartment.

The paint can also act as insulation to the apartment. Painting the apartment with soundproofing paint is quite affordable and at the same time very effective too.

If you are asking me for a recommendation then get this Sure-Max Thick Soundproofing Blanket. Hang or attach this blanket on the wall so that the sound waves would not pass out from the thin wall.
#7. Look For Possible Holes And Fix Them
This method could sound weird or even funny but its reality. There are holes on the wall which can’t be seen with the naked eye because the holes are that small in size due to the aging of the wall. Other than those minute holes there are holes that are done during the apartment construction for wires and other stuff. These holes can easily let the sound waves to pass through it. So the one solution is to fix them. You need to fix them by sealing the holes on the wall.
