How to Soundproof a Room from Outside Noise {8 Ways to Quiet a Noisy Room}

Have you ever tried to sleep on a train, plane, bus, or similar? Guess what, it isn’t easy. That’s why you might want to soundproof your room from outside noise.

Soundproofing a room from outside noise can be a tricky task.

Poorly soundproofed rooms allow noise to seep through the walls and ceiling, causing a disturbance for those inside the room.

Things like snoring, noisy neighbors, and car alarms can make sleeping uncomfortable.

While it may be easiest to move to a new home, a few things can be done to soundproof a room from outside noises.

When people hear of soundproofing, they think it’s expensive.

But it doesn’t have to be, as some soundproofing methods can reduce the level of noise or eliminate it.

This article explores some of the ways you can soundproof your room from outside noise.

But before that, let’s understand how sound travels?

Noise is transported by soundwaves, so as long as there is air, noise is inevitable.

The amount of noise in your room will depend on the type of furniture.

For instance, if your room has more elements of steel, then the noise will be loud.

This is because sound travels faster (approximately 15 times faster) through steel than air.

That’s why many houses are made of dense and heavy materials, such as concrete or timber, as they help block outside noise.

How Do You Soundproof Your Room From Outside Noise

1.    Check the windows for cracks and gaps

Cracks and gaps found in your windows can be the most significant entry point for outside noise. So check all the windows in your room for gaps and cracks, and start your soundproofing project from there.

There are several ways you can soundproof your windows, and each method has its level of effectiveness.

Alternatively, you can choose to combine several soundproofing methods for maximum noise elimination.

  • Window frame inserts sealing

Many windows are made of a single pane, and this allows noise from the outside.

You can prevent outside noise from getting inside by outfitting your windows with a second pane. This helps you create a double wall, with an airspace in between the two panes; thus, blocking the noise.

However, the amount of noise stopped depends on the tightness between the new window insert and the old one.

So, be keen when measuring and installing the inserts while leaving as much space as possible.

This soundproofing method is not cheap, so if you are working on a budget, this is not for you.

  • Window plugs

If you are not big on house lighting, you can use window plugs instead of glass.

They are easy to make and do a great job of keeping noise outside.

  • Caulk sealant

After checking your windows, you may notice gaps between the frame and the walls or some cracks in the windows.

And these cracks and crevices let in noise.

So you can use caulk sealant on these gaps. Alternatively, you can use weather stripping.

  • Rubber gaskets

If you find that your windows are not closing correctly, you can use rubber gaskets.

They are thin strips of rubber and are self-adhesive.

You need to attach the window frame to ensure that the windows are closed tightly, thus not letting noise inside the room.

2.    Soundproofing curtains

You can also choose to use soundproofing curtains.

So choose curtains made of thick and heavy materials, as they effectively absorb the sound.

Note that these curtains will also block light from getting inside, leaving you in darkness 24/7. Thus best for use during the night.

3.    Check the walls

You must check your walls to ensure no gaps or cracks, and afterward, if there are cracks, seal them using caulk.

However, if your walls are thin, the best way to soundproof is to tear them down.

Then build up again while installing sound isolation clips and a new layer of drywall.

This most is the most effective, but also the most expensive.

However, if you don’t have the funds, stick to caulk sealant and supplement with other methods to minimize the noise as much as possible.

Alternatively, you can add another layer of drywall, and this will help you block outside noise.

You are maybe wondering what drywall is.

It is a panel made of sound-absorbing materials, and it is primarily used in ceiling and interior walls.

Adding drywall reduces the amount of noise getting n from outside.

Keep in mind that this method is expensive.

Some of the cheaper ways to keep noise outside include using heavy quilts and paintings and hanging them on the sides that the wall is thin.

Although these methods are not as effective as dry walls, they keep noise outside of the room.

You can also rearrange the furniture inside the room, such that you place bookshelves along the wall.

Place your sofas along the walls instead of the center of the room.

When you soundproof a room, you aim to create a barrier that the noise cannot gain entry.

4.    Seal gaps on the door

You will find that most doors have a gap at the bottom and top part, which act as the point of entry for outside noise—so depending on where you are living, looking for soundproofing methods that can minimize the amount of noise getting in.

First, you need to seal the gaps by using an acoustic sealant.

Apply it between the frame and the walls.

You can also use weather stripping foam tape.


And if the door is thin such that it’s letting all the noise in, you should look into installing a new and heavy door.

And ensure to add a lock door seal kit around the edges as it provides no gaps to let air and sound in.

If you don’t have the funds to purchase seal kits, consider sealing the gaps using blankets. However, these methods are not permanent and don’t improve your room’s aesthetics.

You can also choose to use a rubber door sweep, and since it’s not effective on its own, install rubber gaskets on the inside on the part where the door meets the frame.

Together they seal the gaps, ensuring that no noise gets in from the outside.

5.    Soundproof your air ventilation

Noise also gets in the room through the air vents.

So when you are soundproofing, don’t forget them.

Air vents are holes made in the walls, and they let air flow in freely.

If you find that your room is well aerated without the vents, you can choose to seal them entirely by applying drywall.

However, if they help supply the room with fresh air, you can find other ways to soundproof them.

The most common method of soundproofing air vents is by applying a good sound maze.

This is where you use pipes to absorb the noise from the outside while ensuring air still flows in the room freely.

You can also use quality soundproof blankets and place them at the mouth of the vent.

Ensure that the absorbent side is against the mouth of the vent to absorb the noise coming from outside.

6.    Insulate your floor and ceiling

If you live in an apartment, noise from your neighbors can be irritating, especially when you need to relax, sleep, or concentrate on work.

And as such, you will need to insulate your floors and ceilings.

You can soundproof your floor by placing heavy mats, carpets, and rugs.

These will help reduce the echoes.

However, these are not enough to get rid o the noise.

So before placing your rugs and carpets, consider layering your floor with carpet liners to help absorb the noise.

For your ceiling, you can consider using soundproof padding as they are effective with soundproofing.

It’s advisable to use double layers for maximum efficiency.

7.    White noise generator

You can also use a white noise generator.

This is a device that combines different sound frequencies, and as such, it merges the noise getting in from the outside and cancels it out, leaving with a single sound that is pleasant to your ears.

So if you are sleeping, get yourself a white noise generator device for a peaceful and restful night’s sleep.

8.    Soundproof outside your house

Do you live in your compound?

Are you looking to minimize the amount of noise reaching the inside of your home?

If yes, consider planting tall and bushy plants around the perimeter of the house.

Although it won’t be as effective as other soundproofing methods, the foliage will absorb most noise.

You can also build a tall and thick fence around your house, and you can enhance its effectiveness by using MLV (mass-loaded vinyl).
