How to Soundproof Apartment or Bedroom Door in 2021

1. Mass Loaded Vinyl

Best Option

MLV is the best way to soundproof an existing door.

It’s a door noise blocker and can dampen noise that travels through the air if noise from your hallway distracts you.

A great option for you if you choose to use this method is Trademark soundproofing mass loaded vinyl.

Installing mass loaded vinyl is quite easy just like other DIY methods of soundproofing your bedroom or apartment door in our list.

First, measure the dimensions of your door and cut out the vinyl according to the size. Installing double layers of vinyl on your door would give even better results and transform your door into a sound-reducing door.

The use of mass loaded vinyl is effective but not the cheapest measure to soundproof your door. Another downside to its use is that it always comes in black and may not be your color of choice.

2. Use Sound Deadening Acoustic Foam Tiles On Your Door

Soundproof blankets are a more expensive option to soundproof your door and cheaper alternatives are sound-deadening acoustic panels.

Acoustic panels are available in different shapes and sizes, as well as in different forms including foam and wooden panels.

We recommend the highly-rated Mybecca panels. 

Acoustic panels reduce the amplitude of sound waves, thereby dampening the sound waves that pass through.

This turns your door into a sound-reducing door.
Just like with soundproof blankets, acoustic panels are also easy to install.

Avoid using nails when installing as nails create holes and also damage your door.

Command 17204-12ES hang strip are better alternatives to nails and they are easy to use without leaving holes or residues behind.

3. Soundproof Blanket for Doors

Using a soundproof blanket on your door turns it into a door noise blocker and ensures that less noise can get through.

A good choice of a blanket is Singer safety double-faced quilted fiberglass panel.

Made of fiberglass, it’s great at door noise reduction as it absorbs almost every sound that tries to pass through.

This makes it a good way of reinforcing your door, soundproof wise. Installation is very easy and needs no experience.

All you have to do is hang them unto hooks. The ease at which you can take them down when you want is another appealing feature of blankets.

A downside to the use of soundproof blankets is its lack of visual appeal. It can mess with the beauty of your room and so you might have to take it down often; when you are not disturbed by noise, or when you are not making it yourself.

4. Seal Door Gaps at The Jambs and Header Using a Door Gasket

The function of a door gasket is quite similar to that of a weatherstrip.

It costs more but properly soundproofs your bedroom, apartment and any other door.

By sealing the gaps at the header and jambs of your interior and exterior doors, you can keep out noise, moisture, and even light.

A good door gasket for you to use is the Yotache door insulation and soundproofing tape and the result would be a soundproof door.

It not only acts as a good door noise blocker but is also a heat insulator. This way your air conditioning can work more efficiently.

It’s easy to install, thanks to the strong adhesive back and for environmental safety enthusiasts, this is the product for you.

5. Soundproof Door Sweep

Using weatherstrip and door gaskets takes care of gaps around your door but doesn’t block the noise completely.

This is partly because the biggest gaps that exist in every door are still left open and that is the gap between the door and the floor. Imagine the number of sound waves that can get in through such a gap.

M-D building products 68247 door sweep is not only a good sound absorber, but it’s also sturdy and durable.

It helps you keep insects and dust away, and also prevents the escape of cold air from your room so you can use less energy for your air conditioning unit to keep your room cool.

Unlike weatherstrip and door gaskets, a door sweep is not that easy to install and will take some time to drill and fasten the sweep firmly to the door.

It’s a very inexpensive way to reduce the noise but for better results you should combine it with soundproof blanket or sound deadening acoustic panels.

6. Solid Soundproof Interior Door

Because of the cost of making solid doors, most doors used in homes have a hollow core.

Such hollow doors are very poor at dampening sound and they rather amplify the sound coming in or leaving.

As expensive as solid doors are, they are one of the best doors for soundproofing and constitute the best interior doors for soundproofing.

Apart from the cost of purchase, installing such doors isn’t easy as they are heavy and bulky. So you may need the services of a professional to get it done neatly instead of DIY.

If you still want to make use of your hollow door, you can turn it into a sound blocking door by adding material and mass to it.

You can choose to make use of MLV, wood, or drywall. The idea is to attach this material to your door to make up for the hollow core that it has.

7. Seal The Gap Around Your Door with Weatherstrip Tape

The use of weatherstripping tapes is an easy way to soundproof an existing interior or exterior door.

By installing them around your door and in the gaps around the jamb as well, they deaden sound and ensure more quietness.

If you’re considering using a weatherstrip tape to soundproof doors, we suggest you go for Duck brand self-adhesive foam weatherstrip seal.

Apart from its use to soundproof interior doors and exterior doors too, it also helps with keeping dust, insects, and moisture away. 

Its dimensions of 0.375” x 0.1875” x 360” are good enough for different purposes and apart from its use with doors, you can use it to soundproof your windows too.

When installing a weatherstrip around your door, make sure you apply enough compression.

It’s self-adhesive so installation is easy, but if your compression isn’t enough, there will be a layer of air. This layer of air is a compromise to the door sound insulation and could let sound through.

8. Seal Door Gaps and Cracks Using Insulating Sealant

Locating the cracks and gaps can be difficult especially if they are small.

To locate them, put out the lights in the room and have someone turn on a torch, directed at your door from the other side.

Where there are gaps and cracks, the light will go through and you will be able to see them clearly.

For gaps wider than 1”, we recommend using Great stuff 157906 insulating foam.

You can paint it on it so for uniformity and beauty, you would need to paint it with the same color as your door.

It’s an insulating and airtight sealant and can be used on a variety of doors. You will get a smooth finish after use so no need to worry about disfiguring your door.
And what’s more? You can use it to fill gaps as you soundproof interior doors as well as exterior doors.

For cracks or gaps of less than 1”, we recommend using Red devil 0913 foam & fill.

It’s also a good insulator and can be used to soundproof interior doors as well as exterior doors.

How to Soundproof a Door in 2021 Using Household Items (DIY)

Making use of products from the store can be expensive, and overwhelming for you if you don’t have much to spare.

The good news is that you can DIY soundproof your door without having to bore a hole in your pocket. It won’t be as effective as other methods but it’ll lessen the noise. How is this possible?

In sound blocking doors, you need to understand the way sound travels. Noise passes through your doorway through gaps that exist.

The gaps could be between the door and the doorframe, the doorframe, and the wall, under the door or above it.

Any gap that lets in air at all could let in sound too. To check for the presence of gaps, you could;

  • Put off the lights in the room and have someone on the other side point a torch towards the door. If the light passes through, so can sound.
  • If a candle by the door flickers, it means there is a draft. This means sound can pass through.

1. Use Soundproof Curtains for Your Window and Doorway

Curtains are commonly used on windows but can be on doorways too in sound blocking doors.

Not all curtains are however fit for this, so if you want DIY soundproof doors, look for thick options as they dampen sound better.

Apart from blocking out sound, it also blocks out light and traps heat.

Installing soundproof curtains is not difficult but can be time-consuming. For better results, make use of a slightly bigger curtain for your door frame and have some of the material pool on the floor.

They are not effective on their own to deaden loud sound but reduce the noise to an extent.

2. Use Blankets

The use of blankets is similar to that of curtains. Blankets do not come with grommets so their installation would be slightly different or modified.

You may choose to use a curtain clip that goes over the curtain rod and clips the blanket, or you may install a grommet and use it with your blanket. Another alternative is to nail the blanket to your door.

Just as is the case with curtains, you should make use of the thickest available blanket as thicker blankets deaden sound better.

The blanket should be bigger than the doorway so that it can cover it completely. Having the blanket flowing on the floor will block sound from passing through the underside of the door.

3. Use Pillows and Towels to Form a Draft Stopper

The space between the door and the floor can be a problem. It lets sound through and also allows cool air to escape from the room.

Attaching a pillow or folded towel to the door so that it covers the gap at the bottom when the door closes would help deaden sound that tries to pass through. It’ll also stop the draft.

You can also use towels to make your door thicker if the core is a hollow one. It’ll only make little difference but it’ll make a difference nonetheless. The thicker the towel, the better.

4. Use A Rug

On their own, rugs will not make any significant difference in soundproofing, but when used as reinforcement for other methods, you would notice a difference.

Rugs don’t only dampen the noise; they also make the room more beautiful which makes them a good choice of use.

When choosing rugs, go for heavy ones and keep one on either side of your door to prevent sound from going through.

A good choice of rugs for use in your room is the Safavieh Hudson shag collection.

It’s not only thick but is also very strong and durable. There is no installation process for rugs and you just have to place it where you want.

You can also attach the carpet to the door as a way of thickening it. This way, any cracks that exist on the door would be blocked.

It also serves to make up to an extent, the effect caused by the hollow core of your door.

5. Foam or Yoga Mats

If you have foam lying around that you are not making use of, you could attach it to your door to add mass to it.

Foam play tiles will do great if your kids are done with it. You can also make use of Styrofoam as they would do just fine.

Both materials are easy to attach and with an adhesive spray, you can get the job done. Note however that they are light and not very effective.

6. The Use of Mattresses and Toppers

An old mattress that is not being used can serve to soundproof doors. These doors are those that are not used often but contribute to the entry and escape of sound.

By placing the mattress against your door, you are making the barrier thicker and making up for the hollow core in the door, and the gaps and cracks around the door.

7. Leftover Soundproof Paint

If you have leftover soundproof paint lying around, you could put it to great use by having a good quantity painted on your door.

It seals the tiny cracks that may exist on the door, and also makes the door thicker. The thicker the coat you apply, the more effective it would be in soundproofing your door.

8. Rearrange Your Furniture

Rearranging the furniture in your room can effectively help to lessen noise. By placing the furniture like wardrobes and cupboard against the walls close to the door, you would have deadened any sound that tries to pass through there.

This causes the sound to attempt passing through smaller surface areas and the holes on the door which you would have blocked.

If you have a door that you don’t use, completely blocking it with bulky furniture will increase its mass and help to deaden sound more effectively.
