7 Ways on How to Soundproof a Wall Between Apartments

Want to learn how you can soundproof a wall between apartments?

Well, I shall take you through some of the best and easy DIY hacks to get you started.

As highlighted in my previous article on dampening bass coming through a wall, you will be soundproofing against something known as impact noise/ structure-borne sounds.

While there are fewer risks (such as hearing loss) associated with impact noise than airborne noise, it can be quite stressful, especially when the source of noise is adjacent to your bedroom. (Source)

Luckily, there are different ways on how to soundproof a wall between apartments that are both simple and affordable.

Let’s get started.

Ways on How You Can Soundproof A Wall Between Apartments

The first and most important step I have always recommended for anyone wishing to soundproof their home against neighbors’ noise is having a chat with the neighbors.

If your neighbors play bass music that keeps on sending vibrations through to your apartment, then why not talk to them about the problem?

In most cases, the neighbors may not be aware that they are being a problem.

And a simple chat with them could save you tons of hours and effort trying to soundproof your apartment wall.

Be polite and ensure that you don’t annoy the neighbors in the process.

If you’re not confident enough to talk to them, then why not involve the management or use this guide to learn how to talk to the neighbors.

If this fails, then it’s time to get your hands dirty.

1. Seal All Gaps and Cracks

There are two types of sounds- (airborne and impact noise) when it comes to soundproofing.

The biggest culprits that will allow airborne noise to leak between apartment walls are the gaps and cracks on the wall.

Even small cracks that cut across the walls can be of major concern to leaking noise.

Shared wall elements such as sockets will also act as a medium through which noise travels.

Therefore, it’s always essential to deal with the cracks and gaps before undertaking any other step in soundproofing a wall.

You will need something like Green Glue Soundproofing Sealant or Acoustic Caulk.

If green glue isn’t available in your country, you can try using these 5 Green Glue Alternatives.

Green glue is also perfect for soundproofing against impact noises.

It’s used in almost all DIY soundproofing activities, like in my previous article on soundproofing basement ceiling or even when soundproofing a ceiling without construction.

It does convert the vibrations caused by impact sounds into negligible amounts of heat energy.

2. Hang Acoustic Foam Panels

If you’ve read my previous articles, you’ve probably noted that I’m an avid recommender of acoustic foam panels.

Well, acoustic foam panels have wedges and are popular in recording studios, cinema halls, concert halls.

They’ve become a popular thing in the DIY soundproofing community past few years thanks to their effectiveness in noise reduction.

They are super affordable and highly effective in soundproofing.

However, you need to note that they require careful installation or won’t be effective in dealing with the noise problem.

For that reason, why not check out my step-by-step guide on how to hang acoustic foam without damaging your walls?

3. Hang Mass Loaded Vinyl

Even though I don’t fancy things hanging from my wall in my apartment, I wouldn’t mind the small inconvenience they may cause as long as they do what they’re designed to.

Mass Loaded Vinyl is one hell of a tough a$$ soundproofing material that you won’t ever regret purchasing.

As the name suggests, this material got MASS that blocks are bass vibrations.

Live next to a kid playing hip-hop music?

Worry no more as MLV will deal with the problem quickly.

If you’re a beginner in DIY soundproofing, don’t worry, as the material is super easy to hang on the walls.

4. Add a Layer of Drywall

This method works like a charm, and I’ve always recommended it for all impact noise soundproofing projects.

This method works 100% and can be implemented even when soundproofing against footfall noises from your KING KONG neighbor living upstairs.

However, it’s important to note that adding a layer of drywall is a process that requires a bit of professional expertise.

If you’ve never dealt with drywall material and resilient channels, then I’d recommend you consult an expert.

5. Rearrange Furniture

This is one of the simplest and yet effective methods that won’t cost you a dime, just like soundproofing a door with household items.

Here’s what you should do:

First, identify the common shared wall- obviously, that’s the wall you should emphasize.

Then move heavy furniture such as portable closets, bookshelves, or against the wall.

You should also stack up a large library of books or clothes- the concept is to ensure that you add more mass against the wall, such as to weaken sound vibrations as they travel across the wall.

In case the wall is in your bedroom, then move your bed as far away from the wall as possible. Btw check out my guide on the quietest bed frames on the market today.

6. Mutex Soundproofing Material

Mutex soundproofing material comes almost last on my list as I’m not entirely convinced of its effectiveness.

It’s a product that hasn’t been “tested” in the real world, and hence its effectiveness is something that I’m not 100% sure about.

According to the manufacturer, this product actually soundproof against airborne and impact noises in similar concepts as mass-loaded vinyl and acoustic foam panels.

Have you ever tried it? Please let me know in the comment section.

7. Hit or Miss Soundproofing Products

I’ve dug up the internet and found some astonishing products that people have recommended.

Unfortunately, I didn’t find any scientific data to back up these claims- and that’s the reason I’ve dubbed these products as hit or miss soundproofing products.

They include:

  • Soundproofing Paint
  • Egg Crates
  • Wallpapers
