The Doorway to Silence: How to Soundproof a Door Effectively? (2023)

If you are fed up living in this noisy world, and planning to seal your home from this noise nuisance, you have come to the right place. Here I am going to discuss how to soundproof a door.

Living in a populated city, many reasons irritate a person. One of the reasons is loud noise. And I have found that doorways are among the top reasons to get pass through the noise.

So how to soundproof a door? 

Keep it structurally strong enough to stop noise by replacing it with a solid core door or by adding soundproof blankets, mass-loaded vinyl, or foam panels to the original door. Then, seal the gaps with an insulating sealant or weather-strips, door sweep to prevent air leaks.

There are numerous other methods for soundproofing a door, which we will cover later in this guide so that you can select the most appropriate method for soundproofing a door.

When a lot of people think of soundproofing, the first thing that came to their mind is a high-tech recording studio that removes every whisper of background noise. However, soundproofing is very helpful in making life relax and comfortable.

Soundproofing can make life much quieter and calmer, whether you live in a noisy building, want to be able to listen to your radio and TV at full volume without disturbing others, or need a quiet place to concentrate and relax.

Studies have also found that reducing noise pollution has beneficial effects on our health, decreasing our risk of heart disease, diabetes, and more.

According to the Guardian reports, living near a noisy road is linked to a 25% increase in depression cases, so finding ways to reduce noise pollution is important for our basic well-being, as well as our comfort and happiness.

So you can see, soundproofing is very important, and the solution to soundproof doorways are easy and simple and of course, cheaper than other solutions because you are dealing with existing doorways only.

Below, in this guide, we will go over why soundproofing a door is a good idea as well as some helpful tips on how to soundproof a door. Along with that, we’ll learn about some myths and legal issues concerning soundproofing a door.

Hence, just stay with me and go through each step one by one and in no time you will get rid of this noisy world.

Why Soundproofing a Door Is Important?

If you’re thinking about soundproofing your door, you might be wondering if it’s really worth it. After all, the majority of the room is made up of the walls, ceiling, and floor. You might be surprised at how much noise comes in through the door!

Here are six reasons why a door should be included when soundproofing a room:

1. Doors are often the source of the most noise issues. Since doors are full of gaps, sound can be passed through the gaps quickly. Whether it’s the space under the closed door or the hollowed interior, you’ll always find that a door will let in more sound than any of the walls and floors together.

2. For the same reason, you should consider soundproofing. It will solve all the issues to keep the sound inside. Consider if you’re setting up an at-home music studio, everyone outside your room will hear everything through the door. But you can limit and block sound from escaping by implementing a few of the suggestions below.

3. Soundproofing also provides various benefits like controlling the interior temperature. Because air isn’t moving as quickly through the gaps in the door, you’ll be able to adjust the temperature with a thermostat. If you want to keep your wooden music instruments in good condition, you’ll need to go through this process.

4. Soundproofing your door can also help your soundproofed room’s air quality, humidity, and comfort. Insulating the door keeps pollutants and moisture out, making the space more pleasant to work in or relax in.

5. Soundproofing a door is excellent for security and privacy purposes also. Nobody can hear what’s going on inside, so you won’t have to worry about them listening in. It also allows them to pass by without being bothered by the vibrations of deep bass in recording studios.

6. It adds value to your house. When it comes to selling a home with a soundproofed room, most people will be willing to pay a little more. Producers and people who play drums or guitar at home will love these types of renovations.

Also, there are various situations when a soundproof door will helpful.

1. Work from Home:

If you work from home and need to concentrate, a soundproof door can be a lifesaver, especially if you have a tight deadline. A soundproof door is almost necessary if your work involves sound recordings or video production. However, distractions such as barking dogs, yelling neighbors, honking traffic, crying children, and mooing cows can all get in the way of your work.

And a soundproof door allows you to block out the outside world and concentrate on your work. According to studies, removing conversational distractions such as the noise of human speech increases the productivity by 48 percent and reduces stress symptoms by 27 percent in the workplace.

2. You have noisy neighbors:

Nothing ruins an otherwise perfect living situation like noisy neighbors. If you’re constantly hearing your neighbors yelling, playing instruments, or blasting music, a soundproof door is a great way to get some much-needed peace and quiet.

3. You are the noisy neighbor:

If you play an instrument, listen to music loudly, play video games at full volume, or need to use sound features when working from home, consider soundproofing your door. As a result, the neighbors will enjoy peace and quiet while you work, practice, or have fun.

As you can see, there are several reasons and situations that why you should think about adding soundproofing materials to your door. Never leave it out of the equation! You’ll just end up trying to repair it later, which will cost you more money as prices rise.

How to SoundProof a Door?

Now we will find every possibility that can cause noise through doorways and try to find optimum solutions to soundproof a door.

1. Block Any Partial Gaps or Holes in the Door

If you have completed soundproofing your room and there is a single hole or crack anywhere in the room, all of your hard work and money will be wasted.

As I said before, it is true in the majority of cases with doors; if you have a door in the room, you will almost certainly have some cracks or gaps in the end corner of the door.

1.1 Check the gaps with the flashlight

The first thing you have to do is identify the cracks or holes around the corner of the door which can be done by lighting the room from one side and identify the gaps from the dark side.

For you, the point of focus is now the area through which light passes. As a result, an insulating sealant can be used to fill those larger cracks.

Some of the links below are affiliate links, meaning, at no additional cost to you, I will earn a commission if you click through and made a purchase.

How to Soundproof a Door

I would recommend you to use Green Glue Insulating Sealant which comes in a variety of colors, to fill large cracks, and then wiping the area clean once the insulation is complete.

If you have a very small crack, another option is to use Great Stuff Big Gap Foam, which is can be very helpful for getting rid of that noise passing gaps.

This time, I’m assuming you’ve finished filling small cracks or holes and there’s nothing left around the door’s corner.

1.2 Weather Stripping

While I was looking for another way on how to soundproof a door, I found that weather stripping can also be a great way to seal the cracks and holes in the door.

How to Soundproof a Door

This strip is simple to attach to the door’s corner and can close every gap that allows noise to pass through. But before applying the soundproof strip, just make sure that the surface is clean and dry.

Also ensure that you have a variety of sound-absorbing materials on hand, such as fiberglass, which can block more sound waves. Also, it should be fit in such a way that it is self adhesive to door corners.

I would recommend you to use Door WeatherStripping Foam which I feel is the best product for the given situation. It is ideally designed for waterproofing, windproofing, and insect resistance, but you can experiment with soundproofing a door; it won’t cost you much.

1.3 Install Door sweep

As I have suggested before, now you have filled all the gaps and corners permanently but one thing which is remaining is the gap between the floor and the door, which is the largest gap that needs to be filled.

How to Soundproof a Door

Hence for this, the best solution is ‘Door Sweep’ which not only will keep noise out, but it will also keep insects and dust out of your room.

Another advantage of door sweep is temperature control. Because of cracks and gaps in the doors, the temperature drops slowly when the air conditioner is turned on during the summer months.

Rubber door sweeps can help keep the hot air inside a room from escaping. Also, it’s not as simple as filling cracks; this Door Sweep requires drilling screws and a one-time installation to provide a permanent solution.

However, when it comes to choosing a door sweep, there are a variety of options available, some of which are brush-like and others that are made of closed foams.

It should be made up of multiple layers to prevent sound from entering the room while also allowing you to keep cool air inside.

You can check out Suptikes’s soundproof door Sweep, which has excellent customer reviews and is multilayer, waterproof, and capable of reducing sound 5X times.

1.4 Installing Acoustic Door Thresholds

How to Soundproof a Door

Acoustic door threshold is an alternative to the door sweeps. They are designed to keep noise out from beneath the door. Even if every gap is  sealed and the best heavy mass vinyl sheets are installed, the space beneath the door frame is crucial.

Door thresholds and door sweeps are only distinguished by the fact that thresholds are installed on the floor rather than on the door. This means you won’t have to drag the door sweep across the floor as you open and close it. 

Thresholds are ideal for hard surfaces that make an irritating noise when a door is opened with a door sweep. You can check Frost King Oak Wood Threshold which will be ideal for this situation.

2. Altering the Surface of the Door

If the door is still not soundproof after blocking all gaps and holes, we will need to alter the surface of the doors. Most of the time, this occurs when the door has a hollow core inside.

And since heavy mass blocks the sound better than anything else, we must add a layer to the door’s surface to block the sound. You can soundproof your door using any of the methods listed below.

2.1 Add Mass Loaded Vinyl

 As I previously stated, heavy materials are the best at absorbing sound, hence heavy sheets of vinyl can be used to keep noise out of the door. Most doors, particularly those with a hollow core, dampen rather than block sound.

How to Soundproof a Door

Mass-loaded vinyl can be installed within the door’s centre or on the inside of the room door. It normally requires the use of sound-dampening glue, which often reduces noise. Remember that no form of glue can completely block sound; it can only absorb a portion of it!

I would recommend Soundsulate Mass Loaded Vinyl made with the highest quality materials for superior strength, durability, and flexibility.

2.2 Install soundproof blankets

It doesn’t appear to be the best option for on how to soundproof a door, but it is one of the alternatives if you have hollow doors that aren’t strong enough to block sound waves.

How to Soundproof a Door

Yes, we’re not talking about replacing existing doors; instead, we’re talking about how to soundproof existing doors. Hence, you can buy a sound-absorbing door blanket to hang on the other side of the door where the noise is coming from.

Because of the fiberglass materials and sound-absorbing capacity, it can absorb sound waves. If you have a thin door with insufficient sound-blocking capacity, this is a quick and easy solution. It is also easy to install and remove.

Therefore, I would recommend you to have a look at the Audimute SoundProof blanket that is easy to install and have a thick black coating, and effective at absorbing sound waves.

2.3 Add Soundproof Foam Panels

Soundproof foam panels are an alternative to soundproof blankets. It serves the same purpose as a blanket, but it will be more lustrous and attractive than a blanket. It is one of the best choices among all while figuring how to soundproof a door.

How to Soundproof a Door

Depending on the tiles, you’ll need to use screws, staples, or glue to secure them to your door. Use adhesive Velcro pads on the back of the foam tiles and the wall if you live in a rental property. Make sure they’re secure, or they’ll fall off when the door opens and closes.

This solution is ideal for all types of doors. You can buy 12 Pieces of Acoustic Soundproof Foam in various colors and stick them or hang them with clips.

Hence, you can get Velcro pads to hang on the doors, which are simple to install and can accommodate foams.

If you want to stick to the doors permanently, I would recommend Polymat Stick which is an adhesive spray that is easy to apply and can soundproof a door.

2.4 Install a solid-core Door

How to Soundproof a Door

Another option would be to install a solid core door to keep the noise out. Hollow doors are much worse for sound insulation because they lack mass. However, you can significantly reduce the noise by installing a new solid wood or metal door.

Although wood is much more dampening than blocking, it is still an excellent choice. Metal doors are excellent at deflecting sound waves in the opposite direction, but some fire codes prohibit the use of heavy metal doors inside.

2.5 Installation of Roughs on the Floor

The simplest and most straightforward way to reduce noise from doors is to install a rug. Rugs do not require any installation or labour; simply buy one and place it on the floor.

How to Soundproof a Door

Rugs should be placed on both sides of the doors, particularly on the opposite side of the room from where the noise is coming from. Rugs can absorb sound waves, reducing echo and decibel levels to some extent. But it cannot block the sound completely.

The thicker the rug, on the other hand, the more sounds waves it can withstand, and this is the easiest way on how to soundproof a door.

You may also place a rug inside the room near the door to absorb any sound that passes through the doors.

I recommend searching Amazon for the best SoundProof Rug because I found one which is Hudson Shag Collection Rug or you can also look for other stylish options.

2.6 Coat it with Sound-Absorbing Paint

There is another way to soundproof a door that is by coating it with sound-absorbing paint. Get the sound-absorbing interior paint and choose the one that matches the color of your existing doors as closely as possible.

To use it, follow the directions on the container. It will go on similarly to regular paint but may appear a little thicker.

External noise can be reduced by almost 30% with a sound-absorbing paint coating. Noises from inside the room will not be able to escape through the cracks in the paint.

Remove the door from the hinges and apply several coats of paint outside.

2.7 Insert Soundproof Curtains

You seem to have heard a lot today about how to soundproof a door, but if you still need to soundproof a door, you can install a SoundProof Curtain.

Soundproof curtains on the other side of the door will work fantastically; preferably, soundproof curtains will work as sound deadening.

Therefore, place a short curtain rod directly across the back of the door. Hang a heavy sound dampening fabric curtain or acoustic curtain from the rod. Also if the curtains are thicker, all echo caused on the other side of the door will be absorbed by the curtain.

This is a particularly good option for renters who may not be able to make significant changes to the door’s surface or hardware.

To see if the drapes affect how the door works, open and close it several times after it has been installed. If there was an emergency and you needed to leave, try opening the door quickly to see how the drapes affect the door.

So I would recommend you to check out the WUFENG Door Curtain, which has high material oxford cloth, cold-resistant, and heat insulation, and capable of reducing sound 2X times.

Legal Codes and Requirement

We’ve discussed various methods on how to soundproof a door. Soundproofing is fantastic unless you are breaking any laws or regulations. However, you’d be shocked by how many issues music studios, homeowners, and apartment tenants face while attempting to reduce noise.

Let’s have a look at some of the legal issues:

Soundproofing a Rental

You won’t have to worry about this section if you own a house. Those who rent an apartment, a house, a storage unit, or a garage, on the other hand, should read it thoroughly.

Always check with your landlord before beginning any soundproofing, even if it’s as simple as installing a door sweep. If you start breaking rental agreements, you could face stiff penalties and even get evicted.

Non-permanent solutions, such as hanging a soundproofing blanket over the door, are usually acceptable to landlords, but you should never start drilling or breaking open a door without first getting their approval.

Fire Codes and Regulation

Everyone, regardless of whether they live in a rental or own a home, should be concerned about fire codes and regulations. Many cities, counties, and states have their own set of rules for what is and isn’t permitted.

Soundproofing may violate fire codes because some methods make a door heavier, making it more difficult for someone to escape a burning room. Another reason is that it may interfere with the proper operation of fire and carbon monoxide detectors.

Although soundproofing with the methods listed above is normally appropriate, you should always contact your city’s fire department before beginning any renovations. You could potentially save time, money, and stress!

Myths about Soundproofing a Door

We’ve all tried improvising to reduce the amount of noise in the house. There are dozens of soundproofing solutions available, whether you want to reduce noise from upstairs neighbors or avoid annoying your family with loud music.

Unfortunately, the majority of them are ineffective. The explanation for this is that although these techniques absorb sound, they do not fully block it out. When you soundproof a room or a door, you’re attempting to absolutely eliminate all sounds.

Here are some myths about soundproofing a door:

1.  Regular paint or glue won’t be able to block out sound. There is no science behind blocking sound with these materials because it requires mass and density to do so. That’s not to say they don’t help with soundproofing, but there’s no reason to believe that painting a door or gluing the hinges will make it soundproof.

2. Rugs reduce noise in a room by a small amount, but they do not soundproof it. As I said earlier above that rugs stop the noise to some extent. And many people have tried to block out noise from a loud garage or noisy neighbors with thick rugs. Unfortunately, a rug will only reduce noise by a couple of decibels.

3. Incoming sounds are not completely blocked by egg cartons. They’re also very useful for reducing echoes around the room, so don’t hesitate to use them for that. Egg cartons, on the other hand, will not block out noise from a door. They’ll just avoid echoes with a lot of basses.

4. A room cannot be soundproofed with ordinary blankets, cardboard, foam blocks, or insulation. Again, if you want to reduce noise coming in or out, these are all excellent options. If you use such light, thin materials, you’re probably not going to be able to soundproof the room.

Soundproofing myths have cost homeowners tens of thousands of dollars. Soundproofing is often confused with sound reduction and dampening. The above suggestions mentioned in the methods section are the only solutions you can use if you really want to block out all noises.

Final Solution to Replace the Door

We’ve learned a lot about how to soundproof a door in a variety of ways, but if you’re still unsure about any of them, there is only one way.

If the existing thin door is causing you problems, you will need to increase your budget and purchase a new door. But, to be completely soundproof, that door will require some of the above modifications.

Still, soundproofing a door does not require the purchase of a new door. Soundproofing blankets, vinyl boards over the top, and door sweeps are all options. If you’re mechanically inclined, all the choices are pretty simple to install. Make sure you don’t screw up the job.

And if you don’t want to make any customizations yourself, you might contact a professional to add foam tiles or vinyl inside or outside the door for you.

There’s no doubt that building a soundproofed door yourself is less expensive than hiring a specialist. If you’re on a budget, then see if you can handle the project yourself. None of the ideas on the method list would take more than an hour to complete, so why not give it a shot and save some money?

FAQs on How to Soundproof a Door

1.  What is the best interior door for soundproofing?

An interior door’s soundproofing capabilities are proportional to its mass. Solid core doors are the best because they are extremely dense and heavy.

2.  How much do soundproof doors cost?

Soundproof doors are costly, expect to cost anywhere from $1000 to $5000. Solid core doors, on the other hand, are less expensive and better for soundproofing. But Quality is an important factor in pricing.

3.  Are barn doors soundproof?

A solid core barn door will provide better sound insulation than a hollow core interior door. They are typically more soundproof than other types of doors because they are heavy, weighing 200 pounds or more. In terms of sound deadening, any door made of solid wood or even foam core will perform far better than glass or hollow core doors.

4.  Does a solid door reduce noise?

A solid core door has a significant mass, which is necessary for soundproofing. As a result, a solid core door aids in noise reduction.

5.  Does putting a towel under the door block sound?

A rolled-up towel can be used as a homemade draft stopper, which can be placed under a door to dampen noise from air gaps. It helps to diminish the volume of sounds by closing the gap between your door and the floor.

Conclusion on How to Soundproof a Door

A door is the safest way to keep noise from coming in from the outside, and it is also needed to keep all potential sources of sound waves out.

Therefore, it will be a good idea to keep an eye on all of the above factors and try to implement each one as needed.

If you live in a noisy area or have a small house with different rooms for different purposes, such as a hall for watching TV or listening to music, a room for gaming, and others for office work.

Then keep the focus on doors, and try to minimize as much echo as possible with rugs, curtains, and filling holes and cracks around the corner or door.
