How To Soundproof A Door

Why soundproofing a door is essential?

Doors are also the source of the most noise, making them an integral component of any acoustical care.

A doorway is an enormous gap in a wall and the weakest link for soundproofing. The space around the door sometimes leaks noise. And since the gap at the bottom of the door is always much more comprehensive than the gap around the edges, even more sound will leak in. The fact that most interior doors have a hollow core adds to the issue. Even the doorknob mechanism will make particular noises.

Both of these problems can be solved by soundproofing your door.

Door soundproofing often has the additional advantage of providing temperature insulation. Many of the soundproofing equipment and products often have insulation from extreme temperatures. As a result, your newly soundproofed space would almost certainly cost less to heat and cool.

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

In a variety of circumstances, a soundproof door is needed.

You’re a home worker: A soundproof door can be a lifesaver if you work remotely and need to focus, particularly if you have a tight deadline. A soundproof door is almost necessary if your job requires sound recordings or video production. However, barking dogs, screaming neighbors, honking cars, crying children, and, yes, even mooing cows are all possible distractions. A soundproof door allows you to block out the outside world and concentrate on your job. According to research, reducing conversational disturbances — the noise of human voice — improves productivity by 48 percent and decreases stress symptoms by 27 percent in the workplace.

You have noisy neighbors: There’s nothing like noisy neighbors to put a damper on an otherwise perfect living environment. If you’re always hearing your neighbors shouting, playing instruments, or blasting music, a soundproof blanket for a door is a great way to get some much-needed peace.

If you play an instrument, blast your music, play your TV game at maximum volume, or need to use sound features while working from home, soundproofing your door is a good idea. The neighbors will be able to enjoy peace as you work, practice, or have fun.

How do you soundproof an existing door?

Complete soundproofing of a door necessitates substantial modifications to the current door frame as well as time-consuming building. The door and its assembly will weigh anywhere from 300 to 500 pounds. For specific budgets, buying a solid-core or acoustically rated door is also prohibitively costly.

So, what’s the best way to soundproof a door? Here are some cost-effective, time-saving, and energy-saving alternatives to soundproofing a door.

How to get a soundproof interior door?

The hollow cores of most interior doors allow a significant amount of noise to enter. Try a few of these suggestions to solve your dilemma.

You can install a wooden panel yourself if you don’t mind a small home project. Purchase a big, smooth sheet of plywood that is approximately the same size as your door and is at least half an inch thick from your local hardware store. Break a hole in it where the doorknob would need to go. Apply a generous amount of solid glue to the back of the plywood sheet and firmly press the sheet’s glue side against the door. Fix the plywood to the door with wood screws. The screws will hold the plywood in place, allowing it to absorb sound. Fix the plywood to the door with wood screws. The screws will hold the plywood in place, allowing it to absorb sound.

If the sound is escaping around the sides of your door, consider installing soundproofing rubber around the perimeter. Soundproofing rubber is usually a thick form of neoprene, the same material used to insulate wetsuits from the cold. You’ll have to pry the molding off your door if it already has it. And, along the door’s sides, apply the soundproofing rubber. Fill in small holes and cracks with acoustical caulk or an insulating sealant to provide even more sound protection. Turn off the lights in the room and check for light coming in from the outside if you’re unsure where the cracks are.

Install soundproofing rubber and weatherstripping: When installing soundproofing rubber, make sure to fill in the gaps between the door and the doorframe. Weatherstripping, which is widely used to insulate doors and windows from the elements, is one of the simplest ways to do this. Basic weatherstripping deteriorates over time, but higher-quality variations are available for long-term soundproofing. Remember to apply enough pressure to the weatherstripping around your door. It is due to the pressure that an airtight soundproof door seal can form and obstruct sound waves.

Add a door gasket: Door gaskets are more costly than weatherstripping, but they are usually of better quality. A door gasket, like weatherstripping, fills in the gaps between the door and the door frame. To provide a quality, long-lasting seal, door gaskets are permanently fixed to the door jamb’s sides and top. They’re also made of high-quality neoprene, much like soundproofing rubber. Adjustable door gaskets are also available; because doors sometimes warp or are otherwise not perfectly square, adjusting the gasket for the best fit is a valuable feature.

Add a door sweep: This move is critical for closing the enormous gap that many doors have at the bottom. You can fill your door with all the gaskets and paneling you like, but if there’s a gap at the bottom, a lot of sounds can leak through. Place a door sweep on the bottom of the door to close the gap and obstruct sound waves to avoid this from occurring. Soundproof door sweeps require some effort to install (a drill and screws are required), but the vast improvement in soundproofing is always well worth it.

Install an automatic door sweep: If you want to go all out, you should install an automatic door sweep. A hidden flat-spring mechanism regulates the movement of this type of door sweep. When the door is open, the sweep remains above the floor’s level, but when the door is closed, it drops to form a secure, soundproof seal with the floor.

If adding several soundproofing features to your door seems like too much effort, consider adding an acoustic door panel. These panels are a step up from gluing a sheet of plywood to your frame, but they’re not as costly as high-end soundproofing blankets made of fiberglass. They are available in various materials, ranging from the most popular — foam — to solid wood. They effectively soundproof the door by reducing the amplitude of sound waves that pass through them. You can either nail them to the door or use adhesive strips to prevent damaging it.

How to insulate the interior door?

  1. Cut the door to the correct length.
  2. Clamp stiff boards to both sides of the bottom.
  3. Fill the hollow door bottom with expanding foam insulation.
  4. After the foam dries, trim off the excess with a utility knife and rehang the door.

DIY methods to soundproof a door

Although closed doors do an excellent job of blocking out noise from outside the room, cracks between a door and its casing or threshold allow some sound to pass through. To properly seal these holes, you’ll need to mix and match a few different tactics. You’ll always hear some noise if you add weatherstripping but don’t have a tight-fitting threshold. If you secure all of the areas and surfaces listed in this guide for how to soundproof a door thoroughly, you’ll get the best soundproofing possible.

Determine the space’s requirements—whether it’s just enough noise to fall asleep or total silence for your basement recording studio—and then choose one of these three approaches.

Method 1- Seal the door with spring-metal strips

Install new spring bronze weatherstripping to improve the door seal and prevent noise from entering through the cracks. This form of weatherstripping does the same job as standard vinyl or stick-on foam weatherstripping, but it does so more effectively and for a more extended period—up to 30 years. It’s beneficial for exterior doors, which must be dependable to keep water and bugs out.

Method 2- Seal the door with rubber stripping

Rubber weatherstripping, like metal weatherstripping, is meant to seal and block not only draughts but also noise. Although there are a few different forms of rubber weatherstripping available, the one with adhesive backing is the easiest to use (and the one we’ve covered here).

Method 3- Replace the threshold

Daily traffic can wear down or loosen your existing threshold, which is the raised part of a doorway that serves to cover the line where the flooring meets between rooms while also isolating sounds. Unwanted noise can be kept out of the house by installing a higher threshold, which you can find at your nearest home improvement shop.

Method 4- Install an MLV sound barrier

A mass-loaded vinyl (MLV) mat may provide serious soundproofing for those seeking peace. MLV hung on the back of the door significantly decreases the noise that would otherwise pass in, including its common usage as a vibration cushion under the carpet. This promised silence comes with a hefty price tag: It costs upwards of $60 for a roll from acoustics-focused online stores (approximately $2 per square foot, depending on weight, length, width, and thickness), which is always more than you need for a single door. The thickness varies from 1/16 to 14 inches, with thicker being optimal for sound absorption.

How to soundproof a metal door?

Metal doors present a technical problem since drilling through them is more complicated. Use these suggestions to soundproof a metal frame.

Door thresholds are made of neoprene with rubber protrusions that help fill in gaps at the bottom of closed doors. They attach to the doorway floor rather than the bottom of the frame, unlike door sweeps. If you have a carpeted floor, a threshold at the bottom of the doorway is essential, as even the best door sweep will not completely seal the door with carpet. Some thresholds are flat, while others rise to form a double seal with a door sweep when the door is closed.

Use a soundproof blanket: While soundproof blankets, which are usually fiberglass, are expensive, they absorb sound well and are simple to mount. Suction hooks should be placed on the back of your door, and the soundproof blanket should be hung from them. Soundproof blankets are also a reasonable choice if you don’t need a permanent solution, so you can hang them when you need them and take them down when you don’t.

Vinyl panels, either acoustic or mass-loaded, are simple to use and mount. You may purchase a sheet of vinyl and cut it to match your door’s measurements. Use adhesive strips to protect it. While mass-loaded vinyl panels do not always increase your door’s aesthetic appeal, they help situations where functionality is paramount.

How do you soundproof an interior door?

Maybe you’re an aspiring musician who wants to record a song. Perhaps you’re a YouTuber looking for a quiet location to record audio for your next video. It’s also possible that you’re just sick of hearing the sound of cars or noisy neighbors at all hours of the day and night.

There are various reasons you may want to soundproof a space, especially near the door. But do you think you’ll be able to pull it off? Professional soundproofing, after all, will take days and cost tens of thousands of dollars.

1 Use blanket

It’s so easy, but it’s so powerful. Using blankets to close the crack at the bottom of your door, as amateurish as it might seem, can be an effective way of blocking out some sound. You also don’t have to spend any money. Wad up some blankets you already have and tuck them underneath your door.

2 Acoustic Panels 

Foam and fiberglass are the two most common forms of soundproofing acoustic panels. The former will help suppress echoes, while the latter works to block noise completely. Although foam is less costly, fiberglass provides a more soundproofing bang for your buck. It not only blocks out sound rather than merely reducing echoes, but it also blends in with many new minimalist interior design schemes.

2.Door Seal kits

As we’ve seen, one of the most efficient ways to soundproof a home and reduce noise levels is to seal it off from outside noise sources. While blankets are a less costly choice, they are far from the most powerful. On the other hand, door seal kits are inexpensive and efficient at producing the type of tight seal needed to minimize noise.

A door seal kit comprises three parts: a neoprene door jamb, door bottoms, and a threshold. The latter two will be discussed as separate options further down. When the door is closed, the rubber basket in the jamb will create a seal. These seals go on the inside and outside of a door frame, as well as the top.

3.Automatic door bottoms

Let’s talk about the bottoms of doors now. When a door is closed, a flat spring mechanism is concealed and triggered by pressing a neoprene seal against the door or threshold.

This choice is appealing because it is automatic and does not necessitate any additional effort. Some of the other items on this list, such as blankets, require you to put them in place and then remove them before you can use the door.

Furthermore, automatic door bottoms have a more secure seal than alternatives like door sweeps and blankets. They can also be installed in several ways, giving you a lot of flexibility in choosing how to minimize noise and soundproof your room better while keeping your door in mind.

4.Door Thresholds

Door thresholds (also known as door saddles) are mounted on top of the floor below the door, as discussed in other methods. This is also another element that aids in the creation of a seal. A neoprene bulb can be attached to them. This helps with misalignment problems and creates a closer seal by removing gaps under the door caused by uneven alignment. A threshold may also be used in combination with door bottoms and jambs to form a double seal on both sides of a door.

This is how professional recording studios work.

5.Cover holes and gaps

This one is easy and straightforward, but it’s powerful nonetheless. Sound enters your home through holes and openings, so seal them up. Although you won’t be able to solder your door to the floor or your window to the windowsill, patching cracks and doing some simple home maintenance will help minimize the amount of outside sound that enters your home in the first place.

6.Soundproofing curtains

Putting curtains over your window, as odd as it might seem, maybe another inexpensive way to block out sound. Ordinary curtains, on the other hand, would not suffice. You’ll need to invest in sound-absorbing and sound-blocking curtains. As a result, soundproof curtains are also thicker than standard curtains.

Although soundproofing curtains can be effective against medium and high frequencies, they are far less effective against low frequencies.

7.Barn door Sliding doors

Thickness is one of the most critical considerations when building soundproof doors. Anyone who has lived in a college dorm knows that thin walls and doors do not effectively block out sound, which can be a nightmare. Barn doors, on the other hand, are good and thick. Even so, you still don’t want to turn your house into a barn, which is where barn door sliding doors come in handy.

These doors are a good compromise between heavy, bulky barn doors and thinner alternatives. They suit better with many decor schemes and slide securely into place, providing the all-important sound-blocking seal.

8.How do you soundproof door easy?

  1. See all the gaps and the cracks.
  2. Use Weatherstripping tape on the door.
  3. Use door gaskets.
  4. Use a soundproof blanket.
  5. Use a door sweep.
  6. Place a rug.
  7. Get some soundproofing curtains.
  8. Dampen the noise on the other side.


There are numerous reasons to soundproof a room, as well as numerous methods for doing so. When attempting to soundproof a room, the two fundamental guiding principles are to block out external sound and establish a tight seal in the process. It’s also a good idea to minimize echoes with acoustic paneling improvements if you’re trying to soundproof a space to increase recording efficiency.

Whatever your justification for soundproofing your home, you’ll be able to enjoy the peace you deserve by following one or more of these measures.
