How to Soundproof Your Apartment for a Better Life

Silent Home Hub Soundproof Your Apartment

In ANY living space, a peaceful environment makes all the difference in the world.

And that’s pretty hard to achieve if you live in an apartment in the midst of a bustling city. The noise can be harmful not just to your ears but to your wellbeing too.

There are too many disturbances in an apartment building. Loud neighbors, car honks, chattering passerby.

Worry no more, there are some SIMPLE ways on how to soundproof your apartment!

But before we dive into this soundproofing article, do note that removing noise sources completely is impossible.

Table of Contents

Take a Realistic Approach

You can turn down decibels by AT LEAST 20 to 30 points, but it’s unwise to think this will solve every noise problem.

Rendering sound completely would mean building a room within your apartment or home. It’s doable, but it’s also a lot of extra expense.

If your apartment is next to a lot of consistent heavy traffic, or noisy neighbors, you could improve the structure to reduce the sound.

However, the best solution also involves moving as far away from the source as possible. Consider changing rooms OR worst-case scenario, move to a different location.

We don’t want you to feel soundproofing your apartment is a lost cause. It’s not a hopeless case, to be honest.

But what you need to remember in soundproofing an apartment are TWO things:

  1. Improving the structure helps. Any way to reduce sound in your living space will produce a noticeable effect.
  2. Invest in tools you can use for yourself that can drown out the noise. (We’ll get into more detail about this later).

Simple Ways to Soundproof Your Apartment

To solve your noise issue and stop those noise complaints from your neighbors, there are 4 MAJOR THINGS you can start with:

1. Re-arrange Your Furniture

We mentioned earlier that you can move away from the source as far as possible. That works.

But you know what else also does? Re-arranging furniture.

If you have large bookshelves, placing them wherever the walls are thin can reduce sound by a small notch. Sofas or couches pinned against thin walls help greatly as well.

You’ll also want to make the most out of upholstered furniture.

Upholstered furniture like suede, microfiber, and corduroy are perfect sound absorbers

Wherever sound is the loudest or can pass through easily is the best place to put furniture in.

Re-arranging furniture works best against noise passing through walls. Other than that, they’re room decor.

2. STC Improvement

STC or Sound Transmission Class is a rating of how well a partition (wall) reduces any sound transmitted through the air. Like music or conversations.

Most of this relates to thin walls, resulting in loud neighbors, music, and parties.

The walls you find in most apartments have low STC ratings because of their construction material. 

  • Walls made of Cinder Block are more likely to let any unwanted noise pass through compared to insulated concrete wall blocks.
  • Similarly, metal studs are better at soundproofing than wood studs.
  • The distance between the studs can also improve soundproofing. 24 inches should improve the STC rating.

For any apartment with low STC ratings, it’s common to hear A LOT of noise complaints.

To remedy this, STC improvements involve door, window, and wall soundproofing.

3. IIC Improvement

IIC or Impact Isolation Class tells you how well a floor can absorb impact sound, such as footsteps.

IIC mostly relates to your flooring. Sadly, flooring is the hardest to improve after construction.

Tile and hardwood flooring absorb less impact noise compared to underlay flooring.

A shag rug or carpet has high IIC ratings and can reduce sound transmission effectively. You can expect a 50% reduction in noise if you use a carpet with heavy padding.

4. Seal All Small Cracks and Gaps

This is by far the CHEAPEST, realistic solution anyone can do for their apartment.

You also won’t have to worry about making drastic changes your landlord may not approve.

You won’t need to break your bedroom wall and neither will there be any damage that needs sealing a second time around.

It’s fairly easy to identify cracks and gaps in your windows and even on a wall.

Even the slightest gaps between your floor and baseboard shouldn’t be taken lightly! Seal ALL cracks in your wall, windows, door, and floor to reduce the noise by a few decibels.

The Next Step: 4 Types of Soundproofing For Your Apartment

In this section, we’ll go into greater detail on how to soundproof your apartment wall, door, floor, and windows.

Wall Soundproofing

To soundproof a wall, this might take extra labor on your part.

If you plan to soundproof every wall in your apartment, that may take some time. Not to mention, professional help as well.

So perhaps, you can start small and focus first on soundproofing a room. Reducing sound transmission is easier for a room.

If your apartment isn’t too big either, a soundproof solution may not be as difficult too!

Here are three ways to soundproof a wall:

1. Add an Extra Layer of Drywall

Your walls probably already have drywall installed in them.

The first layer; however, may not be as thick following that noise complaints are common in your space.

Adding a layer will effectively block noise from passing through.

The term for this is also known as double drywall. Hard surfaces can prevent sound waves from passing through and lower noise levels.

We warn you though. Installing drywall might be easy for some, but there’s a lot of technical work involved here too. 

  • We recommend seeking professional help to ensure you install this right!
  • Stub placement, distance, and using the right tools are essential factors. All of which MIGHT take time for you.
  • If you have a busy schedule, this also isn’t as easy as a simple DIY method.

The good news is, adding drywall only costs a few dollars. Soundproofing a wall with this method is inexpensive but it will require additional help.

Quick note: Before you buy the drywall, make sure you get at least a 5/8 inch thick one. A thicker layer will improve the soundproof effectiveness of your walls.

An alternative to adding another layer of drywall is to put up acoustic wallpapers instead.

2. Install a Mass Loaded Vinyl (MLV)

A mass loaded vinyl looks like a huge black plaster. They’re HIGHLY effective solutions for soundproofing your walls.

They’re also very heavy and dense materials so, be careful when handling them. The effect an MLV produces in reducing noise from passing through is highly noticeable upon installation.

Here’s how to install one:

  1. Measure your wall from top to bottom. Deduct at least 1/8 – 1/4 inch from the total height.
  2. Unroll your MLV. Cut the MLV with the specifications you measured in Step 1. Use a utility knife when cutting.
  3. This third step will need two people. Starting at the upper corner of the wall, apply the MLV over the studs. Your MLV sheet must be straight along with the ceiling. The sheet must also be evenly spaced between the floor and ceiling.
  4. For fastening the MLV, use roofing nails or screws with washers. A pneumatic cap stapler should be fine too. Place fasteners every 8 inches apart side to side, and starting from the bottom to the top.
  5. You can add a strip of PVC tape on the wall seams.

Soundproofing your walls take more effort than you think. But for the love of a more peaceful apartment, it’s worth it.

For safety reasons, consult professional help.

Also, if you don’t install these properly, MLV sheets can peel off over time. All the more reason to have a professional help you when installing these on your walls.

Just in case, here’s a video on how to install MLV on your walls:

Bonus Tip: Using MLV with extra drywall is a highly effective soundproof solution. You’ll be able to reduce sounds passing through your walls if you combine these two methods.

3. Soundproofing Paint

You can cover walls using soundproof paint to reduce the noise level up to 12 decibels. Pretty neat, right?

  • Standard applications for soundproof paint are THREE layers. One layer can reduce between 2 to 4 decibels of noise.
  • For the best applications on your walls, work on critical areas first.
  • Apply the paint on the walls with the highest priority. For example, soundproof rooms are more important than a soundproof living room.

Now that we’ve covered all the methods for soundproofing your walls, the next section will cover doors.

Door Soundproofing

Reducing noise for your doors isn’t as labor-intensive as soundproofing a wall.

Most apartment doors are hollow core doors. Which makes noise transmission easily happen.

To check if you have a hollow core door, a knock should produce an echo sound.

Either way, here are 4 WAYS TO REDUCE SOUND in your apartment door:

1. Green Glue Sealant

The best way to treat apartment doors with a hollow core material is to seal any door cracks and gaps with Green Glue sealant.

  • Turn off the lights and notice any areas where light passes through. These areas are what need sealing.
  • Simply apply the sealant to your front door and you’ll reduce sound fairly well.

2. Door Sweeps/Automatic Door Bottom

Sealing isn’t enough. To treat bottom gaps in your door, door sweeps or soundproof draft stoppers are budget options to reduce incoming noise.

Automatic door bottoms are more effective in removing noise at the bottom of the door. Although, they’re MUCH more expensive.

3. Use a Soundproof Blanket

These sound-absorbing blankets are dense and heavy enough to block noise coming from outside.

Applying them is also extremely simple and easy thanks to their Velcro material.

They’re quite pricey too but will last you a long time.

4. Install a Solid Core Door

This is the most expensive option but also the most effective in reducing noise.

Because of its thick material and layer construction, solid core doors are guaranteed noise blockers.

Window Soundproofing

Since there are fewer windows in your apartment than your walls, reducing outside noise coming from windows shouldn’t be as difficult or strenuous.

Windows are also much smaller so you have nothing to worry about.

Here are two of the best options for reducing outside noise:

1. Window Seal Kit

Using a window seal kit allows you to install a window seal track in front of your existing window.

This separates the two glass layers, creating a dead space and greatly reduces noise transmission.

You can also opt to use them with window inserts along the window frames to fully keep sound waves from entering.

Here’s a video to help you:

2. Soundproof Curtains

These are COST-EFFECTIVE solutions for dampening noise in your apartment.

You can easily hang them on your window and it’s practically a hassle-free, sound-absorbing solution!

If you want to reduce any echo and want an effective sound deadening product, these sound-absorbing curtains won’t disappoint.

Blackout curtains are pretty effective sound barriers in an apartment complex!

Go for brands like Nicetown or Best Home Fashion.

Floor Soundproofing

Floors are the hardest to deal with in an apartment when it comes to noise reduction. This is because of workmanship issues.

Initial floor construction usually uses underperforming IIC rating materials.

Take note that using acoustic panels and anti-vibration pads are NOT the best options for sound reduction. They also won’t protect your floor.

The best materials to use are foam and sponge. Because of their porous nature, they’re PERFECT for reducing sound on your floors.

Here is a list of options to use:

1. Tredaire Colors Red Underlay

Tredaire provides the best underlay if you have a carpet in your apartment and want to reduce different noises.

The material is thick enough to reduce noise from high foot traffic, and any apartment with heavy furniture.

Tredaire comes at a steep price though, so for a budget option go for Carpenter Deep Step.

2. Super Gold Underlay

For laminated and engineered wood flooring, Super Gold underlay is the best option.

It’s perfect for reducing sound and protecting your floor at the same time.

Why Should I Use Underlay?

Using soundproof carpet underlay protects the floor in your apartment and can absorb sound. They also contain foam and sponge materials. 

These make excellent sound reducers thanks to their tiny little holes and protect your floor or carpet too.

Extra Advice: Quick & Affordable Ways For A Good Night’s Rest

But wait, there’s MORE! Damn, right there is.

We’ve covered the realistic approaches and the technical methods to soundproof your apartment (or cope with noisy neighbors at least).

So here are some extra, practical ways you can do:

1. Use Earplugs

Earplugs are lifesavers. They don’t reduce sound in your apartment, but they’re perfect for getting a good night’s rest. 

They’re also the cheapest solution unless you’re serious about moving to a different location.

You’ll need to be a little selective of which earplugs to use though. Not every earplug works well for you.

Above all, you want an earplug that provides the best comfort to your ears.

ALWAYS check the Noise Reduction Rating (NRR) of the earplug you choose.

The higher the NRR, the more effective the earplug. Currently, the highest NRR for earplugs is 33.

Flents Quiet Earplugs are the perfect balance of NRR rating and comfort. With an NRR rating of 29 decibels, these effectively reduce noise to a high degree.

The material used is also malleable and expandable so they’ll fit nicely into most ear canal sizes.

2. Talk to Your Neighbors Politely

Well, there’s always the civil option, right? You can politely ask your noisy neighbors to lower their voices. Or whatever privacy preferences you have for keeping the noise down.

This might be easier to do if you were living with someone. A best friend, perhaps?

This method doesn’t always work, but it’s worth a try out of respect.

If that doesn’t work, talking to your landlord might be more effective.

Although, I’ve heard many experiences of this not going so well for both parties. 

Unless your neighbors are mature and respectful enough, this shouldn’t be a huge problem.

If you hit a dead-end, you can go for earplugs and well, the third option.

3. Invest in a White Noise Machine

Ever wondered about the white noise trend? Sound machines like this are more pleasant than a car honk or shouting next door.

White noise machines are the best distractions to any other noise source around you.

A majority of people use white noise machines to help them fall asleep. Although you can use them in other ways too.

How this works is diverting your attention through the white noise the machine makes.

  • White noise uses ambient soundscapes like a crackling campfire, for example.
  • Other sounds include chirping crickets, ocean/waves, rain, jungle, etc.

We recommend going for the LectroFan or Marpac Dohm white noise machine if you plan on buying one.

Or better yet, give them a go through Spotify Music and connect it to your Bluetooth speaker! Spotify has a ton of white noise to put you soundly asleep.

Final Thoughts

Soundproofing your apartment can be an overwhelming task.

If you are someone with a busy schedule on your hands, you might want to rely on quick fixes first.

  • Any technical alterations to your apartment structure might be better alongside a professional.
  • This will help you save A LOT of time and just enough for completing it during the weekend.

If you have the time and patience, feel free to go all hands on deck.

Just remember there is no such thing as a perfect noise-free environment.

Unless you take drastic measures like building a room within another room for your small home gym or small home office, these can be doable noise-free projects.

Ultimately, using all the methods mentioned here and the quick fixes can exceptionally help reduce noise.

We hope all these ways to soundproof your apartment was helpful!
