There can be several reasons for the disturbing sounds that you are facing in your apartments such as thin walls or inadequate insulation. If you are wondering how to soundproof a wall between apartments, you can begin with one or more of the methods listed below.

Sealing Gaps

The gaps in the apartment walls, even the tiniest of them can let in a great amount of noise and you will not even recognize that it is coming from those places. Make sure to check for these in the walls of your apartment that can be resulting in such noise. 

If you find any gaps on your wall, use a sealant to cover them up.

An adhesive like green glue compound which is a gypsum-like substance can be used to seal those. It is also a soundproofing compound. 

Green glue can basically help in absorbing sound waves to convert them into heat energy. You can clean the area surrounding the holes or gaps and after letting it dry, apply the glue.

Furniture Placement

To accomplish how to soundproof a wall between apartments completely, furniture placement is extremely essential.

The echo effect makes an empty room more likely to release noise. Since there is nothing to block the reflection of noise, it will hit the ceiling and then bounce back on the walls.

Hence, you should stack a row of furniture against the walls to prevent the sound from bouncing through the walls. 

If the furniture items are big and they do not touch the wall behind them, the air gap will absorb the sound rather than passing it over through the wall. 

The more furniture you can stack against the walls without disrupting the decorations, the better the sound absorption. 

Bookshelf Against The Wall

Apartment walls are quite thin. You can place a bookshelf against them to make it thick and dense. Fill it with books so that no space is left for noise to sneak in.

Placing a large bookshelf against the wall and stacking it up can help you solve this problem because it acts as a second wall.

This will not block out the noise completely, but it will significantly minimize the amount of noise coming into your apartment.

Mass Loaded Vinyl

Putting up Mass-loaded vinyl on your walls can save you from noise as well as temperature issues. Mass-loaded vinyl is a coating material best known to soundproof the walls.

  • Tape the seams using duct tape.
  •  Make sure it does not cover your electrical switchboards.

Finish installing drywall

Installing Drywall

Installing layers of drywall can significantly decrease the noise coming in. A drywall is made up of materials like gypsum, sheetrock, viscoelastic, and custard board. 

These materials increase their mass and density which makes it effective to block out the noise sneaking in through the walls. 

You can apply green glue on your drywall and then put another layer of drywall on top. Green glue is effective if applied between two hard surfaces. 

Installing drywall is not an easy job and you will need a professional to do this work however, this is an impressive way if you are wondering how to soundproof thin apartment walls.

Soundproof Curtains

Soundproof curtains are one of the cheapest solutions to the shared wall noise problem. They have acoustic properties that can absorb sound. Another advantage of these curtains is that they provide thermal insulation. 

And when you learn how to soundproof thin apartment walls and decide to opt for this method - you’ll also find out that is perfect if you live in a cold area. 

You can hang these types of curtains to reduce sound transmission and the cold coming from the thin walls as they are heavy and thick.

acoustic foam and panels

Acoustic Foams And Acoustic Panels

You can cover the walls by learning how to install acoustic foam or panels. The acoustic panels are made of polyester material. They also reduce thermal energy from the outside wall surface.

They are designed in such a way that they stop sound from bouncing off hard surfaces.

Even though they do not block out the noise entirely, you will notice a significant difference in the amount of noise coming in.

Soundproof Paint

An affordable way to make yourself a soundproof apartment wall is the use of soundproof paint. Soundproof paint is manufactured to reduce the sound by 50%. This paint is quite viscous and is applied in layers to increase mass resulting in a thicker wall.

They absorb the sound and do not let it flow through the walls. Furthermore, they are inexpensive, easy to apply on the walls without needing a professional, and they also provide insulation to the apartment. 

Foam Padding

Foam padding your walls can provide the required thickness to reduce the sound coming in. Foam padding consists of high-density rubber.

The thickness of the pad makes it effective in order to soundproof apartment walls, especially on how to reduce bass noise from neighbor. These pads can be installed on the wall as well as on the floor.
