How to soundproof a room from outside noise

Soundproofing a room from outside noise doesn’t have to cost much and can be done in a few simple steps. 

To soundproof room from outside noise, follow these steps below:

Check the windows 

Windows are one of the biggest culprits that allow sounds to come into your home.  

Check to see if there’s a draft around the window frame. 

if there is a draft, you will feel a slight breeze which means that noise comes in as well. 

You can also check to see if any air is getting through the windows when they are closed.

You can move your hand around the perimeter of the window or you can use a candle to see if the flame flickers. 

Just be extra careful if you do use the candle method. 

The other test you can perform is to check to see if the glass is too thin to keep sounds out.

If that is the case then you may have to get new windows or double pane windows. 

While it is best to get double-paned windows, it can be quite expensive so you can opt to install window inserts instead or other cheap alternatives. 

Window inserts can be another layer of glass or transparent acrylic. 

If you are working on a shoestring budget then you can seal gaps around the window with acoustic caulk.

Modify the walls

The walls also play a big part in allowing noise to come into the home. 

Just like windows, they are cheap and expensive ways of soundproofing the walls. 

How to keep sound out of a room with damaged or thin walls?

If you want fully soundproof walls then it would be best to tear the existing wall down and add some sound blockers. 

This process can be time-consuming as well as expensive so unless you have the budget for this, you have to look at other ways.

Interior walls can develop cracks, holes and gaps over time which allows outside noise to get in easily. 

One easy fix is sealing those gaps and cracks with caulk sealant. 

You will find that some walls are thin which makes them transmit outside noise easier so adding mass to the wall can help you stop outside noise from coming in. 

Drywall is a panel made out of sound-absorbing material and can be used in interior walls or ceilings. 

All you do is add an extra layer of the drywall panels to enjoy their soundproofing properties. 

However, adding a double layer of drywall will further reduce the amount of noise coming in. 

You can also add MLV to the walls as well.

If installing drywall or MLV is way out of your budget then you can try hanging some heavy quilts, soundproof blankets and wall decorations to the affected wall.

  • Purchase more than 1 for Free Shipping
  • Effective for sound absorption (0.85 NRC Rating), NOT for blocking sound
  • Improves sound quality in a room by reducing sound echoes and reverberation

If the look of a soundproof blanket on the wall turns you off then you can choose some acoustic foam.

They may not block sound fully but they can absorb some of the sound coming in from outside.

You can also try to move some furniture around in the room since the basic idea is to create a barrier between the room and the source of the noise.

Soundproof the door

Most interior doors now are usually hollow on the inside which means that they do not block sounds as much. 

If you find that there is a large amount of sound from outside getting into the room then the door is probably the reason. 

You can get a new door with a solid core and have that put in place. 

However, replacing the door can be expensive and you will also have to find a professional to get it fitted which will incur additional costs. 

A cheaper way to soundproof your existing door is to use a soundproof blanket. 

Soundproof Blankets are usually thick and have many layers that help to block out outside noise.

You can simply hang the soundproof blanket at the back of the door and secure it in place with tacks or adhesive. 

Another reason doors allow noise to come into the room is because of the gap at the bottom of the door when the door is closed. 

You can use a door sweep to block this gap left between the door and the floor.

Alternatively, you can use some weather stripping at the bottom as well. 

Other areas where sounds can come into the room are through any gaps and cracks around the perimeter of the door and door frame. 

Use either weatherstripping tape or acoustic sealant to seal these gaps and cracks. 

Work on the air vents

how to keep sound out of a room

Noise from outside can also come in through air vents.

Air vents are basically large holes in the wall that allow fresh air to come in freely which means noise comes in as well.

If you find that you don’t necessarily need your air vents then you can block them entirely using filler spray. 

In some instances, you should not block air vents if you wish to have access to some fresh air or if they help with the way air flows through your home.

If that is the case, then you will need to soundproof the air vents instead. 

You can create a sound maze or a honeycomb-like structure in the vent the trap sounds. 

Both these structures can reduce noise and maintain airflow at the same time.

Insulate the ceiling and floors

Soundproofing the ceiling and the floor may not be necessary in order to get rid of outside noise. 

If you are living in a house then your upstairs and downstairs neighbors are probably family members or roommates. 

However, if you live in an apartment building you will definitely need to soundproof both the ceiling and floor. 

This is because the noise from upstairs can be quite annoying, especially impact noise. 

To soundproof your ceiling you can choose from several options. 

The first option includes a drop ceiling to keep sound out of the room.

If you do go with a drop ceiling you can also choose some acoustic hangers as well to further block out sounds. 

This is because acoustic hangers reduce the noise from vibrations in the suspended ceiling. 

The other option involves placing acoustic panels on the ceiling as well to keep noise out of the room.

Tackle the outside

There are a few changes you can probably make to the outside of your home to reduce the amount of reaching you. 

You can make changes in your yard if you have one.

While it may not do much, you can transplant some tall and bushy plants or trees close to the windows. 

This will not prevent the sound from reaching you but it may soften loud and harsh sounds as they pass through the foliage.

The other option is to build a tall fence which is a bit more efficient especially if your house is in line or lower than your existing fence. 

If you are going to be building a fence or fixing your fence, try to build a thick fence so that it can absorb some of the impacts of deeper bass sounds. 

You can also add MLV to the fence so that it can be twice as effective at blocking out sounds. 

Other options include putting in a small waterfall so the sound of water will kill other sounds or at least make them quieter. 

Other Options
