Soundproof a Kid’s Room: 4 Best Ways

So you have decided to soundproof your home, and just like any part of it, you also want to soundproof your kid’s room, right? Soundproofing a kid’s room is something which could be very necessary, especially if you are living in a big and noisy city.

Beautiful kids room

Your kids should be able to get a beautiful and long sleep, just like any kids should. But if you are living in a noisy area, that could be practically impossible. Although during my childhood, I did not live in a noisy area, now I am living close to the city center of Stockholm, and I am starting to realize how necessary soundproofing can be.

I am not a father myself yet, but I have hands-on-experience in soundproofing. Therefore, I have decided to use my personal experience to create a guide on soundproofing a kids’ room with the best and yet most cost-effective methods possible.

To soundproof a kid’s room, you will need to soundproof the room’s door, windows, ceiling, and walls. You will find it easy to do with the right guide.

If you are living in a noisy part of the city and you are planning to soundproof a kid’s room then you need to check this guide. Alright, let’s get started!

Methods to Soundproof a Kid’s Room

Soundproof a Kid’s Room Door

I have decided to start with the door because many people forget to soundproof the door the way they should. They fail to realize that the door is where most of the noise pass through.  Maybe there are some people out there that might not agree with this, but if you have the same opinion as me, then let’s just start with the door.


Install a Moving Blanket

The best option you have is actually to replace the current door that perhaps is very hollow and thin with a wooden door like this one on Soundproof Interior Door e-commerce. It could do the trick.

Nevertheless, being aware that your kid’s room might already have a wooden door or maybe that is not something you are looking for, I would suggest you install a moving blanket to the existing door.

There are many low-cost soundproof blankets available on the market. Most of those moving blankets have fiberglass fibers that are widely known for their excellent sound absorption. Therefore, people often use them when soundproofing a door.

There are two ways to soundproof a kid’s room door with moving blankets: to hang them on the door or pin them to the door.

Hang the Moving Blanket on the Door

Step 1

To be able to hang these blankets, you should use three grommets on one edge of each blanket. Starting with the large cutter and wood, use a hammer to drive the cutter through the blanket and into the wood. This procedure should result in giving you a hole the right size for the grommet.

The grommets come in two halves. The first half is designed to go through the hole, and the second half goes over the top with the material sandwiched in between, and then it’s crimped together.

Step 2

Place the grommet that goes through the hole on the bottom anvil and then place that under the blanket through the hole. Place the other half of the grommet on top with the curved side up. Use the punch head and a hammer to round over the center part of the grommet, crimping the two halves tightly together.

Step 3

Once the grommets are in place, cut the rope into nine-inch long segments, and seal the ends. The rope is looped through the grommets and held with a knot.  The loops of rope can now slip over the studs on the spring clamps and can hang the moving blanket on the door! That’s it!

Pin the Blanket to the Door

As previously mentioned, there is also another way to install moving blankets to the door of the kid’s room, and that is to pin it. I prefer this than to hang it because this way, it will cover all the gaps and be more effective in soundproofing the kid’s room.

I believe that everyone knows how to pin things; that’s why I am not going to get into too much detail. I will only recommend you to use small nail pins rather than drawing pins because the first ones are way stronger and are less likely to fail.

On the other hand, if for whatever reason you can only use drawing pins, then make sure to use plenty so the blanket won’t get detached easily.

Seal the Holes and Cover the Gaps

Another important thing that people often forget when soundproofing a kid’s room door or any door, in general, is to seal the holes and cover the gaps. Regardless of which option you might choose for soundproofing a door, there always will be some gaps between the door and the floor.

If you forget to seal those gaps, then you can’t say you have done an excellent job because the noise will leak through them, and both sides can hear it. To avoid that, you should purchase this weatherstripping tape on Amazon.

This pressure-sensitive adhesive-backed foam is the simplest weather stripping to add and is relatively economical. Adhesive-backed foam is manufactured in rolls of different lengths and thickness found in both rubber and plastic.

When the door squeezes the foam, the foam will seal out the air. Such weather strips provide an additional cushioning effect that silences door slamming.

Keep in mind that this form of weather can last from 1 to 3 years, but not permanently.

Mini-Guide on Applying Weatherstripping:

Step 1

Choose to work on a hotter day. When the temperature is at least 60 degrees Fahrenheit, the adhesive could be applied much easier and much more effective.

Step 2

Clean the door surface with detergent and water before applying the weather stripping. Make sure there is no dirt or dust left. This should be done so the weather stripping could be applied easier and could stay there for a long time.

Step 3

Cut the strips with scissors, but don’t yet remove the backing paper of the weather stripping.

Step 4

Gradually peel the back paper as you apply to place the adherent moisture strips from one end. If you have a hard time applying it at the start, stretch the foam until the seal between the foam and backing breaks.

Step 5

Install strips to the doorjamb on the hinged foot.

Step 6

Apply two more strips to the doorstop. Try to close the door, in case the corner of it touches the weather stripping, try to trim a top piece of foam on the hinge side.  And there you go!

Soundproof a Kid’s Room Window

Soundproof a kids room window

Another place from where most of the noise comes in and out is definitely the window. Soundproofing the window is especially important if you want to remove all the noise that comes from the outside of your home.

The window is exposed to the outside world more than any other element of the room; therefore, you should make an effort if you want to soundproof a kid’s room window effectively.

There are many different ways on how to soundproof a window, but here I will only list you the most cost-effective ones that can still do the job pretty well.

Buy Sound Dampening Curtains.

Before I start, I would first like to mention that it is not entirely sufficient. However, sound dampening curtains are also a cost-effective way to reduce external noise coming from the window. Also, they are particularly good at lowering the echo from the room.

One thing I can advise is to buy sound dampening curtains that cover the entire window from top to bottom. This helps you get better results in soundproofing your kid’s room. You could use these sound dampening curtains to also decorate your kid’s room. To do that, check out these sound dampening curtains on Amazon that are specially made for kid’s bedrooms.

The most important thing to remember is that it would be best to use this method in combination with others to ensure good results.

Install a Barrier Panel

Another cost-effective way to soundproof a kid’s room window is to install a barrier panel.

So What is a Barrier Panel?

A barrier panel is a standard panel made of acoustic foam that is used to absorb noises and sound reflections. It is often used as a soundproof material.

One thing that I will suggest is to measure the window and then purchase it so you will be sure that it is the right size. What’s more, buy a barrier panel which size will surpass the surface so it will provide an excellent grip for air.

If you are living in a super noisy area and you want your kid’s room to be soundproofed effectively, you can install double panels or use it in combination with other methods. If you want to learn more ways to soundproof a window, then make sure to read this article that took me like a week to put together.

Install an Extra Layer of Acrylic

Installing an extra layer of acrylic to the window is another super option you can use in order to soundproof the baby room window. So now you are probably wondering how it works; to solve that doubt, just keep reading.

First things first, if you want to install an extra layer of acrylic, you should attach a metal frame to your window. When you finish that, you should then go ahead and install that extra layer of acrylic to the window. I will suggest you make sure that you have created an airtight seal as well.

Remember that this will not remove all the noise from the room, but you can use this in combination with the methods I listed above, and you are good to go!

Seal the Window Gaps

Caulking gun

Previously I mentioned that if you want to soundproof your kid’s room effectively, you should also seal the gaps and holes on your door, and that’s what you should do with the window. There are different methods on how you can do that. However, the most common one is to either use weather stripping, just like I explained above, or simply to do that with a caulk.

To do that, you will obviously need a caulking gun like this on you can find on Amazon.  Of course, the caulking gun itself can’t do anything if it is not loaded with caulk. I would suggest you use this on that you can also find on Amazon.

Once you have purchased all that, then it’s time to start working.

Mini-Guide on Sealing Window Gaps

Step 1

The number one thing you should when sealing the gaps on your window is to check for air leaks. To do that, make sure to get some candle and light it right in the corners where you believe there is a sound leak. It’s straightforward; if the flame slightly moves, then there is a gap that you should seal.

Step 2

Obviously, you don’t want to seal the gaps that will stay like that forever without previously cleaning the dust and dirt on your window. So yeah, grab a cloth and do that. 

Step 3

The next thing you should do is to load the caulking gun. To do that, you should break a lock on the top and cut the nozzle at an angle of 45 ° and an opening where the filling will go. Place the nozzle at the top of the cartridge and place the gun into it by moving the base of the canister.

Step 4

This is the final step and here what you should do is to apply some pressure on the caulking gun in order to force the filler in the area causing the leak. After that, just push the nozzle in motion around the joint. Make sure to wipe the remaining caulk after you finish each section. To do that, you should mix water and detergent.

Soundproof the Walls and Ceiling

Install Acoustic Panels

Many people believe that soundproof a kid’s room walls and ceiling could be a challenge, but it really doesn’t have to be that way. Installing acoustic panels as a way to soundproof the walls and roof could be a very time-efficient and cost-effective solution.

There are available in different sizes, colors and, both boards and fabrics so you can be creative and not only use them for soundproofing purposes but also as decorations. Most of them are designed in a way to stop sound bouncing odd hard surfaces, which makes them even more amazing.

If you are having trouble choosing which one you should purchase, I will recommend you take a look at these acoustic panels on Amazon. They are even used in home music studios, something that talks a lot about their efficiency.

Install Thick Wallpapers

Installing wallpaper on a wall

This is something that I will recommend you do in combination with the previous method because thick wallpapers themselves would not be that effective. Yes, it will help you to reduce the noise and decorate your kids’ room, but it won’t wholly soundproof it.

Nevertheless, if you decide to give this method a shot, then here is a great Star Wars wallpaper on Amazon that your kids might love it.

Installing wallpaper is not as complicated as many people think. To help you out, make sure to check out my mini-guide:

Mini Guide on Installing Thick Wallpapers

Step 1

The wall must have a smooth surface. If necessary, you can sand the imperfections, or apply a wall putty or resin on the irregular parts. It is essential that the wall is free of dust so that the adhesive or glue of the wallpaper well adheres. If you want to wash the wall, make sure it is dry before installing the wallpaper.

Step 2

Measure the wall and cut the strips of wallpaper to prevent the paper from moving under its own weight while you are applying it. To ensure that the paper covers the wall, leave at least 4 inches at each end of the wall.

Step 3

Some wallpapers already have their own adhesive; you just have to remove the protector and stick it to the wall. It is not recommended to remove the protector altogether to avoid sticking in unwanted places. If the wallpaper does not have adhesive, you can buy this special wallpaper glue on Amazon.

Step 4

Once taped to the wall, press the wallpaper against the wall with a smooth cloth to remove air bubbles or cracks in the wall. Repeat it until all the walls and ceiling are covered, and that’s it!

Place a Bookshelf Against the Walls.

This does not apply to the ceiling, but it still can help you out with the walls. If you want to soundproof the kid’s room even more effectively, then try placing a bookshelf against one of the walls. The reason why I suggest this is because it will add mass and massive objects are able to resist vibration and reduce sound transmission.

The best thing is that this is entirely free, it does not take much time, and it could also look super decorative, especially if your kid loves reading. And if it doesn’t, then this is an excellent way to inspire your kid to start reading more.

The only negative thing is that it will take some extra space from the room, so I will recommend you this only if the room is more spacious.

Soundproof the Floor

Install Mass Loaded Vinyl (MLV)

Mass loaded vinyl

Mass Loaded Vinyl (MLV) mainly comes in black, which means you’ll need a bit of fabric to cover it and or even paint it if you don’t want your kid’s room floor to be black.

Installing mass-loaded vinyl is not an easy task, but it is one of the most effective ways to soundproof a kids room floor or any floor in general. If you decide to go with this method, then check out this MLV on Amazon. It also comes in different sizes.

To learn to install MLV on the floor, check out this article, it has all the necessary details you will need to effectively soundproof your kid’s room floor with MLV.

Once the MLV has been installed, you should apply acoustic caulking between the different vinyl sheets to seal those spaces, just like I described above.

Buy Interlocking Floor Mats

If, for some reason installing MLV is not something you are looking for, then maybe you should purchase interlocking floor mats. Not only are people often using them for carpeting kids’ rooms, but they are also a great floor soundproofing solution.

Luckily, there are many colorful floor mats like these on Amazon that look super cool, so no kids would say no to them.

Once you get them (make sure to purchase as much as you need to cover all the room), lay them down, and connect them all together.

One thing to remember is that they will not altogether remove the sound, but they can definitely reduce it!

Final thoughts

Soundproofing a room, especially one of your kids, is not an easy task because not only should it be soundproofed, but it should also look cool, right?

I hope that this guide will help you to do that without spending too much money and making enough effort. And most importantly, I hope your kids will love it!
