Shut Out The Noise!

How to Soundproof a Door

A door is the most critical part of soundproofing a space, whether in your house or workplace. Arriving at home implies entering a peaceful environment where comfort should be your closest ally, but what if your neighbors are noisy?

The door is, without a doubt, the largest entrance in most locations, and it is the one that anybody would try to soundproof first. So, today we will learn to soundproof different doors and the materials you can use to easily soundproof them.

So, let’s get going.

How to Make a Door Soundproof?

In this section, we’ll go through each of the various causes of door noise and attempt to identify the most cost-effective way to soundproof the door in the process.

Seal the Cracks and Holes in the Door

Holes and fissures mainly cause acoustical leakage. Identifying these flaws and cracks is the first step. If the door is quite old and you haven’t fixed it in a while, you may find many of them. Therefore, you will need to use extreme caution in this case.

Turn the lights on in the room on the other side of the door; you are trying to soundproof to find out whether any gaps are allowing the sound to enter the room. You must then enter the space where you are soundproofing the interior door. 

Lock the door and extinguish the lights. After doing this, you ought to be able to see the light slipping through the crevices and into the pitch-black room.

A door seal may prevent these common openings and fractures from occurring. It is a simple and affordable method of soundproofing a door.

Make sure you have sealed and closed the door as well.

Bolster the Door’s Weight

The door’s mass is critical since it acts as a sound absorber and a solid material for reshaping. Without any bulk, noise may readily infiltrate through the crevices and holes, even when you’ve stopped it before it leaves your house.

This method of soundproofing a door is thus more effective. For example, using solid materials like plywood, drywall, or MDF will give the door more heft (medium-density fiberboard).

However, you must choose a material that complements the door. Since failing to do so would result in an odd and unsightly result, the door will also be difficult to shut. Hence, search for a complementary substance.

Insert Soundproofing Foam

Soundproof foam is a substance that absorbs sound to lower noise levels. Soundproofing walls, ceilings, and doors are possible with this product.

When you can’t sleep due to the noise, it’s a horrible thing. Noise pollution is a significant issue. Using soundproof foam will prevent noise from entering your room and waking you up at night. The best approach to obtaining a good night’s rest is to use this method.

Therefore, you can also use soundproof foam to soundproof your door. To do this, an excellent place to start is by accurately measuring your door. Finally, purchase a piece of soundproof foam the same size as your door next.

Next, you’ll have to trim the foam to match the door. Put the foam in the center of your door and secure it. To prevent outside noise from entering, make sure it’s well sealed. You’ll likely have to fill out four to six applications and ensure to keep air voids to a minimum. When applying the spray foam insulation, go slowly and patiently.

You can use an under-door sweep if you want to keep noise from coming in or out of your home. With this method, you can soundproof a door at a fraction of the cost. You will seal the bottom gap with the help of a door sweep, and the noise from the next room won’t be as loud. A door sweep has the added benefit of keeping bugs out of the home.

Temperature regulation is the third justification for a door sweep. In the summer, the cracks and gaps of the doors cause the temperature to decrease slowly when you turn on the air conditioner, which leads to extra power consumption.

Using rubber door sweeps can also stop the loss of hot air within a room. Ensure that you get the proper one for your door’s size. Because if it is the wrong size, it won’t fit correctly and won’t work to block the noise.

Then, using the included screws, you must fasten it to the door. Ensure that the sweep touches the floor entirely.

Because if it doesn’t, the sounds will still come through. It may not be a big concern if you live in a quiet area. However, it might be a significant problem if you reside in a bustling metropolis.

Install Weatherstripping Between the Floor and Door

Using weatherstrips to tighten a wobbly door is an excellent soundproof method. Weather strips come in a wide variety of forms. Furthermore, they may reduce noise levels by up to 50% and are of foam, rubber, or vinyl material.

Weatherstripping is a standard solution for bedrooms, home theaters, and other areas where noise is an issue. They are straightforward to put in. Some things to think about while selecting door weatherstripping include material thickness, construction type, and the method of fastening it to the door.

You can install weather stripping to a door may be installed in a variety of ways. The adhesive is the most frequent method since it adheres to the door and the floor. Another option is to secure the weatherstripping to the door and the floor using a clip system.

Finally, you may use screws to affix weatherstripping to the door and the floor.

Install a Solid Core Door

Today, most interior doors in every house are hollow core doors. Mostly you will find that the only doors with a solid core are those going outside of the home. They are either in the front or the rear (exterior doors).

Pounding on a door can determine whether it is hollow or solid. The hollow door will produce an echo and shake if you bang on it, while a solid one won’t. Typically, thin sheets of wood comprise a hollow core door.

In contrast to a hollow door, a solid wood door is totally solid. It is far more difficult for sound waves to get through a solid door. When it comes to sturdy doors, some people believe that only steel doors are solid doors, but this is not always the case. A wide variety of solid wood doors would fit right in at your house.

Add Door Gaskets

Since door gaskets are more costly than weatherstripping, this is the approach to employ if you want a higher level of quality. When placed, a door gasket closes up any openings between the door and the frame.

Door gaskets are permanently attached to the top and sides of the door jamb for a reliable, long-lasting seal. High-quality neoprene is the standard soundproofing rubber in these products.

Placing a Soundproof Blanket

You may use soundproof blanket to prevent noise from entering or exiting your room. If you reside in a crowded city and want to reduce the volume of the noise, this may be useful. Studies have shown that the soundproof blanket is a good noise absorber.

Find the correct size for your door before using a soundproof blanket. It is then time to connect it to your door using the screws that come with it after you have determined the proper size. Make sure the blanket is entirely on the floor. If it doesn’t, the noise will still be there.

Use of Acoustic Panels

One of the most flexible soundproofing options on the market is acoustic panels.

You may attach acoustic panels to the front of the door using glue and nails or screws. You can prevent sound waves from entering by placing them in such a way. You can improve soundproofing further by using acoustic panels, as studies affirm.

Due to their low cost and wide availability, acoustic panels are an excellent option for home and business use. Furthermore, they may block a broader spectrum of frequencies than conventional soundproofing materials. The main drawback is that they are more expensive than traditional options, such as soundproofing blankets.

Soundproofing your bedroom door (which is most likely hollow) is easy and may be done in many different ways. Moreover, blocking or absorbing noise is necessary when you cannot control it directly.

Use Rugs

Try to reduce the noise around the source as soon as possible. For example, a tile or wood flooring in the kitchen, living room, or dining room prevents the sound from getting absorbed. A simple solution to this problem is to acquire several low-cost kitchen rugs and one large rug for your living or dining area. Rugs will absorb the sound before it reaches your room.

Use Sound Absorbing Foam or Fiberboard

A layer of thick sound-absorbing foam or 3/4-inch medium density sound-deadening fiberboard cut to the dimensions of your door may make a significant difference. Four wood screws are all you’ll need to secure the foam or fiberboard to the bedroom door. Put washers around the screw heads before installing the foam on your door. The washers are required to keep the screw heads above the foam piece.

Use Door Gaskets

You can seal any door area susceptible to sound leakage by using a set of detachable door gaskets. They are mounted on the door’s frame as a noise barrier and prevent unwanted sounds from entering.

Use Soundproof Curtains

Another option is to hang thick curtains over or to the left and right of your entrance to reduce noise; studies have proven that they serve the purpose. Therefore, when you’re ready to bed for the night, pull the drapes over your door’s front or sides to assist in muffling and absorbing noise.

How to Soundproof a Hollow Door?

Following are some of the easy DIY methods to soundproof a hollow door:

Increase the Hollow Door’s Mass

You should give the door as much weight as you can. You can only block sound waves effectively by bulk. The best option for soundproofing Hollow Doors is sound deadening foam. Your door can open and shut properly thanks to this straightforward installation, which is often less than an inch thick.

Soundproofing projects may benefit from the usage of acoustic foam panels. The purpose of acoustic foam panels is to absorb sound rather than block it out. In addition, these panels prevent the room’s sound from leaving.

Mass-loaded vinyl soundproofing barriers comprise salts, sands, and tiny metal particles, making them more ecologically friendly than standard soundproofing materials. Contractors use MLV barriers in drywall and plywood constructions. However, if your door’s hinges aren’t strong enough, you may not be able to install them.

Fill the Door’s Gaps

The space between a door’s bottom and the floor reduces a room’s soundproofing. Purchase a door sweep or draught stopper to remedy the issue. Not only will it assist in filling the bottom gap and stopping unwanted outside noise, but it will also help improve the thermal insulation of the space.

Use Soundproof Curtains or Soundproof Blankets

You may hang acoustic curtains in front of your entrance by installing a simple curtain rail above it. Pull them shut when you close the door to limit the noise. Blankets designed to block out the sound are also an excellent option. The denseness of the material prevents sound and air from passing through it. It is something you can do by yourself.

How to Soundproof a Garage Door?

You may use the following methods to soundproof a garage door:

Fill in the Gaps

It’s advisable to seal the holes surrounding the garage door with weatherstripping so that air or noise can’t go in or out. Foam insulation, vinyl, or rubber are all suitable options. Rubber seals are the finest choice for steel doors.

Use Sound Deadening Mats

When it comes to steel door roll-ups, sound-deadening mats are an excellent choice. It’s more probable that they’ll work on your metal door if they’re successful in dampening the sound in your automobile.

Seal the Windows in Your Garage Door

You can solve reoccurring garage door noise issues by installing window plugs such as weather-strips, acoustic panels, or acoustic foam panels against drywall or garage walls.

Install Panels of Acoustic Foam

Installing acoustic foam panels over your garage door might help keep noise from escaping and enhance the acoustics in the area.

The acoustic foam at the doorway bounces sound waves back into the room, where they are absorbed and dampened, helping to keep sound from escaping while simultaneously enhancing the room’s acoustics.

Buy as many acoustic foam panels as you need to cover the garage’s walls completely. Make use of spray adhesive or green glue to fasten the panels to the wall to complete the installation. Make sure to obtain any essential measurements first, and then trim the material to size using a utility knife if you need it to suit the door.

How to Temporarily Soundproof a Door?

Carpets or Thick Curtains

Follow these methods to temporarily soundproof a door:


In soundproofing, adding bulk is one of the most important criteria. The object’s mass absorbs sound waves as they travel through your solid core doors, preventing them from reverberating. Non-elastic mass is preferred, although anything solid and heavy will work. Considering how excellent carpets are in soundproofing, it’s usually a good idea to have some on the floor while trying to keep things quiet. Carpet is so effective because of its weight, which is due to its many materials.

To begin, fill up the opening at the bottom of the door with carpet. You can prevent a lot of noise from getting in via the interior doors.

Use Thick Curtains

Installing thick curtains in front of a door is a quick and easy way to soundproof it temporarily. In a manner comparable to that of windows, this is the simplest method to add bulk to a door, and doing so will result in some degree of sound absorption.

How to Soundproof a Barn Door?

Here’s how you can soundproof a barn door:

The Hole and Gap-Sealing Weatherstrip

Weatherstripping will cover any minor gaps or holes in your barn door, keeping undesirable sounds out. Weatherstripping not only fills in the cracks and holes but also aids in the reduction of a room’s energy use. It saves you money by keeping the room at a comfortable temperature for a lengthy period.

An Additional Layer of Wood

You know that the more substantial and thick a door is, the less sound it will let flow through it. Therefore, we recommend that you may add extra wood to your barn door to make it thicker. You may cut plywood or fiberboard to size. However, before you begin cutting, take the necessary dimensions. Fiberboard is a superior choice if you have to select between the two.

Glue a coat of green glue compound to the rear of the barn door after the pieces of fiberboard or plywood are ready to be used. Next, gently connect the panels. Screw nails into the door’s outside corners to ensure the panels don’t fall out.

For a final touch, you may add soundproofing paint to the door if desired.

How to Soundproof a Closet Door?

These methods will help soundproof your closet door:

Invest in Acoustic Panels

Acoustic panels may help absorb noise. The ease with which you can install them and the effectiveness with which they absorb unwanted noise make acoustic panels an excellent choice.

You’ll notice a reduction in unwanted echoes and lingering frequencies when installing acoustic panels in your closet.

Install Bass Traps Made of Studio Foam

Foam sound absorbers, known as “studio bass traps,” are designed to capture low-frequency noises in recording studios. Recording studios utilize them to improve the sound. In the corners of your closet, low-frequency vibrations from a kick drum or subwoofer may reverberate throughout the room. As a result, you’ll get a muddy, indistinct sound that’s annoying to you and your neighbors. Using foam bass traps prevents these undesirable outcomes from occurring.

Repair the Holes

Sound uses cracks and holes to get in. As a result, you should check your closet for any holes or cracks in the walls, ceiling, or flooring. You can use weatherstripping or acoustic sealant to fill up any holes or gaps in your closet wall or door.

How to Soundproof a Sliding Glass Door?

You can try the following methods to soundproof a sliding glass door:

Fill Up All the Gaps

If your sliding door has developed cracks due to age or exposure to the elements, the first step is to seal them. Make sure there aren’t any cracks in the seal that might let outside noise in.

You need to approach the door cautiously with your hand. For example, you may tell whether there is an incursion by feeling the chilly air (especially in colder areas).

A millimeter gap may significantly impact the amount of noise you can hear from the outside. Therefore, you need to use a specific soundproofing caulking to ensure it is completely sealed.

Reduce Noise With a Door Sweep

Installing a little door sweep on the bottom of an inside sliding glass door is another wonderful option for securing the bottom of the door. For example, if your kitchen connects to the laundry area through a sliding glass door and your washer and dryer make a lot of noise, you can add a sweep to keep it quiet.

Soundproof Curtains

Assuming your sliding glass door leads outside, you already have a curtain blocking part of the noise that comes from the outside. You may also use a thicker soundproof curtain to block light and, more crucially, noise.

How to Soundproof a Door Frame?

Follow the methods to soundproof a door frame:

Door Gasket

Gaps in the sound path amplify the sound. A gasket is a good option if any spaces are under or around the door frame. They’re simple to put up and do a great job of blocking out any noise around the door.

You must install the door gaskets once you have removed the door frame. No more sound will come in through the open gaps after you’ve lined up the internal gasket and closed the door frame properly. You can find door gaskets in a wide variety of styles and prices.

Gap Foam

When using gap foam, you must use a thick recipe. As the gap foam develops, it builds up in bulk, forming a formidable barrier between your room and the rest of the world outside.

Foam the inside of the door first, then work your way out, ensuring to fill up any gaps along the way. Most hollow doorknobs have holes running through the middle; therefore, this is an excellent solution.

How to Soundproof Metal Door?

Here’s how you can soundproof a metal door:

Door Sweep

Weatherstripping is an effective method if you want to block sound from cracks and holes surrounding the door. However, what about the most crucial entrance, the area under the door and floor? Door sweeps comprise materials that absorb sound and prevent insects from entering a home via doors.

Be mindful, however, that the installation process for this kind of soundproofing is not quite as simple as that of the gasket or weatherstripping. Therefore, to secure the sweepers to your floor, you will need to use a screw and drill.

The use of door sweeps may help you save money on your energy bills since they stop air from your air conditioner from leaking out of the door gaps.

Door Gaskets

Door gaskets and weatherstripping both function similarly to achieve the same end effect. The gasket is a little bit more costly, but it is also more effective. It is the primary difference.

A gasket works much more effectively on a metal door for the magnetic strip to have a good hold on the door and effectively block out any outside noise. However, this method does not need as little effort as the weatherstripping, and it takes a little more time.

Noise-Cancelling Blankets

Soundproofing blankets are constructed of fiberglass and may be draped over doors to block out noise temporarily before being pulled down and stored away when they are no longer required.

The aesthetic value of these soundproofing materials is low, which is a significant drawback to using them. Regardless of the benefits, it may provide, you may not want it displayed anyplace in your workplace if you have a refined taste.

Final Words

Follow the procedures outlined above to lessen the amount of noise entering your home and eliminate those noisy neighbors driving you crazy!
