11 Effective Ways to Soundproof a Closet

If you are a musician, then practicing your guitar (or any other musical instrument) in a garage makes it nearly impossible to hear yourself, and your neighbors will hate you. Soundproofing a closet could easily be the most important thing you can do for your home studio. 

How to soundproof a closet? Hang drapes or thick curtains on both sides of the door of a closet. Insulate the walls by adding some sound-deadening material such as acoustic panels or foam tiles. To minimize sound leakage, seal the cracks in the walls, ceiling or flooring by applying acoustic sealant.

Soundproofing is important if you need quiet space for recording audio or making music. There are many different ways to soundproof a closet. In this article, I’ll give you some practical tips on how to soundproof a closet.

How to Soundproof a Closet?

How to Soundproof a Closet

To soundproof a closet, weatherstrip the door to block noise from entering the closet. Additionally, install soundproofing materials on the walls such as insulation and soundproofing foam. Also hang heavy blankets on the inside of the door to muffle sound from outside the closet.

Soundproofing a closet is a fairly simple process. While it will not completely eliminate sound, it will significantly reduce the amount of sound that travels through the walls of the closet. Here are some great ways to reduce the noise coming into your closet and escaping from your room.

1. Soundproof the Door using Weather Stripping 

Soundproof the Door using Weather Stripping

If you want to soundproof a closet, it’s best to start with the door. This is because the door is the most likely part of the room to make noise. This will help keep noise from leaking out into the rest of your home and prevent unwanted sounds from entering your closet.

Quick Tip: For better results, use foam weather stripping around the top and sides of the door for maximum noise reduction, and use a metal weather strip on the bottom of the door to seal out air leaks.

You don’t need to install heavy-duty rubber strips along the sides of your doors or even put foam gaskets around them. 

Just buy some stick-on weather stripping at any hardware store, cut it into strips and apply them along the edges of your doors where they touch the frame.

Here are some steps to apply weatherstripping to the door:

  1. Measure the width of your door frame.
  2. Buy enough foam weatherstripping for each side of the door frame. 
  3. Cut the foam weatherstripping to size using scissors or a utility knife.
  4. Remove any existing old weatherstripping from both sides of the doorframe using a putty knife or paint scraper (if necessary).
  5. Use silicone adhesive to secure one end of the foam weatherstripping inside one side of the doorframe (this prevents it from moving around once installed).
  6. Stretch out the foam weatherstripping across both sides of the doorframe so there are no gaps between pieces or sections.

2. Seal the Cracks and Crevices

Seal the Cracks and Crevices

The first step is to seal any cracks or holes in the walls, floor or ceiling. This is an important step because it will prevent any sound from escaping or entering through these areas.

Quick Tip: Sealing closet joints will help prevent sounds from traveling through the walls.

You can fix cracks, gaps, or holes by using any one of these methods below:

Caulking 

The most basic method for soundproofing a closet is to seal up all the cracks and crevices with a caulk. 

Caulking works well when it’s used correctly because it creates an airtight seal that prevents sound as well as any moisture from entering the crack or hole.

You can buy caulking at hardware stores or home improvement stores. The best type of caulk has silicone in it, but there are also high-quality acrylic caulks available if you want something that’s more affordable.

Acoustic Sealant

Acoustic sealant is another great product to seal cracks. It is a type of flexible, synthetic rubber material. It’s a thick, adhesive substance that fills cracks and holes in walls, ceilings, floors and other surfaces. 

The sealant is made of latex or vinyl and is available in liquid form or as an aerosol spray.

Sealing cracks with acoustic sealant will not only reduce noise pollution but also improve the overall quality of your home’s insulation system.

Spray Foam

Spray foam is a great choice for sealing cracks, because it is easy to apply and doesn’t require any special tools.

Spray foam works by expanding when it comes in contact with air. This creates an airtight seal around the edges of the cracks in your walls and floors. The foam expands up to 30-60 times its original size, so it fills in gaps quickly and completely.

The spray foam will last longer than caulking or other types of sealants, which tend to dry out over time and crack again.

3. Soundproof the Walls using Mass Loaded Vinyl (MLV)

Soundproof the Walls using Mass Loaded Vinyl

Mass loaded vinyl (MLV) is an excellent choice for soundproofing a closet because it’s made of a dense material that absorbs noise. The MLV has mass and weight, so it can absorb energy vibrations from sound waves. 

This means that when sound hits the MLV, it bounces right back out instead of traveling through the material and into your room.

The material can help reduce noise from outside sources, such as outside traffic, as well as noises from within the home.

Here’s how you soundproof a closet with Mass Loaded Vinyl:

  1. Remove all items from the closet. You’ll want access to both sides of the wall while you’re installing MLV.
  2. Remove the existing drywall from the walls of your closet (if necessary).
  3. Cut new pieces of mass loaded vinyl large enough to cover each wall in your closet
  4. Apply spray adhesive to the backside of each piece of mass loaded vinyl and press firmly against the wall until it sticks
  5. Repeat the steps for each wall in your closet.

Quick Tip: You can install drywall over your Mass loaded vinyl, but you will have to install studs first if the closet doesn’t have any.

4. Cover the walls with Acoustic Panels or Foam Panels

Cover the walls with Acoustic Panels or Foam Panels

Cover the walls with acoustic panels or foam panels. These are both effective at blocking out sound, but they do have different uses. 

Foam panels are more effective at blocking out lower frequency noises, while acoustic panels are better at blocking out high-frequency noises. 

If you have a lot of noise coming from a particular area, such as someone talking loudly in the next room over, then you might want to use foam panels because they will be more effective at blocking out those sounds.

Here are is the main difference between acoustic panels and foam panels:

Acoustic Panels

  • Acoustic panels are made of resilient materials that absorb noise and prevent it from traveling through a wall or ceiling. 
  • They’re made up of layers of insulation and acoustical materials, like fiberglass or mineral wool, which reduce the amount of sound that passes through.
  • They’re also affordable, come in many sizes and colors and can be cut to fit any size opening. 
  • The downside is that they don’t cover a large area, so if you want to cover an entire wall or ceiling, you may need to buy several panels.

Foam Panels

  • Foam panels are another option for soundproofing a closet. These are typically made from polyurethane or polystyrene foam, which helps block unwanted sounds by trapping air inside its cells. 
  • Since the air is trapped inside its cell structure, it can’t vibrate and make noise when you shut the door.
  • They’re available in different thicknesses and densities, which makes them ideal for different applications. 
  • Some foam panels come with adhesives already attached so you don’t have to worry about adding glue yourself.
  • Foam panels can be used to cover large areas of the ceiling or the walls.

5. Add Bass Traps

Add Bass Traps

Another thing you’ll want to do is add bass traps into the corners of your closet. Bass traps can be made out of acoustic foam or any other material that will absorb low frequencies in the room. 

The goal here is not to block all sound but rather dampen it by absorbing some of the sound waves before they reach our ears. This way we can still enjoy music but not have to worry about anyone hearing us playing it.

If you have a large closet, you can install bass traps on each side wall, as well as the back wall, for maximum effectiveness.

Do you know: Bass traps are used to eliminate low-frequency sounds, like the bass in music or the rumble of traffic.

Bass traps work by absorbing sound rather than reflecting sound. They can be made from many different materials, including fiberglass, mineral wool, polyester foam, and acoustic foam. The most common type of bass trap uses fiberglass panels.

6. Cover Floor with a Soundproof Carpet

Cover Floor with a Soundproof Carpet

Carpet is the easiest way to reduce the noise coming from your closet. It will help absorb some of the sound and cover up any creaking floors. 

A soundproof carpet will help absorb any vibrations that come from walking across the floor and also reduce some of the noise coming from inside the closet.

Soundproof carpet is made from a soft material that is plush to the touch and comfortable to walk on.

Add carpet padding with carpet (Optional)

If you want to make the most of your closet soundproofing, you can add carpet padding with carpet.

Carpet padding is a thin layer of material that is glued to the underside of your carpet. This material gives a soft feel to the floor, but it also reduces noise and vibration. 

The main purpose of carpet padding is to prevent sound from traveling through your floor into the room below.

7. Use Soundproof Blankets for Walls

Use Soundproof Blankets for Walls

Soundproofing blankets are made of fiberglass and are meant to block out sound. They’re lightweight and easy to install, but they can be expensive.

Before installing soundproofing blankets, the first thing that you need to do is make sure that you have enough space on each side of the opening in order to put them up properly. 

Your walls should be covered in these blankets so that they absorb all of the noise coming in through the opening into your closet. 

Once they’re up, make sure that there are no gaps between them and the wall itself, as even the smallest gaps can get the noise in and make your efforts worthless.

Here are the step by step process to hang the soundproof blankets on walls:

  1. Measure the length and width of your closet walls.
  2. Buy enough soundproof blankets to cover both sides of each wall, plus a little extra for overlap at the top and bottom.
  3. Hang one blanket on each wall, overlapping them by about a foot at the top and bottom so that you can’t see through them.
  4. Tape the blankets together where they overlap so they stay in place when you move around inside the closet or take clothes off hangers.

8. Decouple the Walls from each other

To decouple the walls, you’ll need to install a decoupling wall system between the closet and the adjacent room. This is an effective way to reduce noise transfer between two rooms.

If your home has a neighbor on one side of your closet, this will be especially important. Soundproofing between these rooms will help keep noise from reaching your neighbor’s ears.

But what exactly is a decoupling wall system?

It’s made up of individual panels that are connected by screws at regular intervals along their length, and in some cases, across their width as well, to create an air gap (or foam insulation) between two surfaces.

These panels are typically made from gypsum board (drywall) or fiberglass insulation. Both materials perform well when used as part of a decoupling wall system because they’re light enough not to add more weight than drywall alone but thick enough not to allow any sound through them easily either.

9. Rubber Flooring (Soundproofing Carpets Alternative)

Rubber Flooring

Rubber flooring is another good option for soundproofing a closet. Like foam, rubber can be cut to fit the size and shape of your closet.

This is an easy and quick solution that requires almost no maintenance. Rubber floors also have excellent durability, making them ideal for areas with heavy foot traffic or large amounts of movement and traffic.

Rubber floors come in many different colors, making it easy to match existing decor or create a new look. They’re available in rolls that are easy to install on any surface including concrete, wood and tile flooring as well as ceilings so you can use them anywhere (not just closets).

There are even self-adhesive versions if you don’t want any permanent installation work done!

10. Install a Door Sweep

A door sweep is a rubber or plastic strip that attaches to the bottom of the door. When you close it, this strip sweeps along the floor and keeps out dust and dirt. It also helps keep noise from escaping your room.

If you have an old wooden front closet door with no drywall behind it, then adding a sweep may be enough for you to make your space more soundproof. 

11. Get a Noise Canceling Headphone

Get a Noise Canceling Headphone

If there’s one piece of equipment that will make your life easier when it comes to practicing guitar or singing in your closet, it’s a noise-canceling headphone set. 

These headphones have microphones built into them that pick up outside noise and then cancel it out by creating an opposite waveform that neutralizes the original soundwave.

This will help block out any ambient noise from outside of your closet. 

You can also use earplugs if you need extra protection against outside noises during practice.

Benefits of Soundproofing a Closet

Following are the benefits of soundproofing your closet and how it can benefit you in the long run.

Improved Privacy

If you have a shared room with someone else, or you simply want to keep your personal conversations private, soundproofing your closet can provide you with the privacy you need.

When soundproofing, you can add insulation materials to the walls, doors, and floors of your closet to create a sound barrier that prevents sound from escaping or entering. This is especially helpful if you’re on a phone call, recording music, or practicing an instrument.

Better Sleep

Noise can greatly impact the quality of your sleep. If you have a closet that is located near a noisy street, or your noisy roommates are always coming and going, soundproofing your closet can help you get better sleep at night. By reducing the amount of noise that enters your room, you’ll be able to fall asleep faster and stay asleep longer.

Increased Home Value

Soundproofing your closet can also increase the value of your home. If you’re planning on selling your home in the future, potential buyers will be impressed with the added feature of a soundproof closet. Not only will it make your home more attractive to buyers, but it can also increase the overall value of your property.

Enhanced Audio Quality

If you’re a music lover or enjoy listening to podcasts or audiobooks, a soundproof closet can provide you with enhanced audio quality. By eliminating external noise, you’ll be able to hear the details of your favorite tunes or podcasts more clearly. This is especially helpful if you’re recording music or podcasts, as the sound quality will be greatly improved.

Reduced Stress

Noise can be a significant source of stress for many people. Whether it’s the sound of traffic outside or the noisy neighbors upstairs, constant noise can lead to anxiety and stress. By soundproofing your closet, you’ll be able to create a peaceful and quiet space where you can relax and unwind. This can greatly reduce stress levels and improve your overall well-being.

Conclusion

Soundproof your closet by adding more insulation in the wall. The thicker the wall is, the less sound will come through it. Install acoustic foam panels on walls and carpet on the floor. This will help absorb any sounds coming through the walls and make them less noticeable.

Soundproofing a closet can be done fairly easily. The most important things to consider are the type and thickness of the materials used in the construction of the closet, and any external factors that might affect the equipment.

Follow the instructions in this guide to soundproof the closet easily and effectively.

Frequently Asked Questions (Soundproof a closet)

How do I stop noise traveling through walls?

The most effective way to stop noise traveling through walls is to create a physical barrier between the two rooms. This can be done with drapery, carpeting or furniture. Another simple solution is to add insulation on the wall that separates your room from the noisy neighbors.

However, this may not be feasible if you live in an apartment building or condo complex where the walls are shared with other units and there is no access to the outside of your unit.

Another option to reduce sound traveling through walls is by adding an additional layer of drywall over existing drywall. It may not be cheap but it will definitely help with noise reduction.

How do you turn a closet into a studio?

Soundproofing is essential in converting any room into a recording studio. For the walls and ceiling, put up some acoustic foam to reduce echo and noise from outside sources. Carpet the floor so that it will absorb any sound from footsteps or dropped objects.

What is the cheapest way to reduce noise through walls?

The cheapest way to reduce noise through walls is to install acoustic insulation behind the drywall. This can be done either by drilling holes in the wall studs and sticking fiberglass batts into them, or by using spray-in insulation that can be sprayed directly into the stud cavities.

You should also look into getting thicker windows, which will help keep sounds from entering your home.

Other options include moving furniture away from walls and using carpet padding as an additional layer of soundproofing.

Do closets absorb sound?

Closets are small and enclosed spaces that can be great for soundproofing. The walls are thick, so they help to dampen sounds from outside the closet. They’re also often made with a material that absorbs some of the sound waves to prevent them from escaping into other rooms.

However, a closet is not an ideal space for recording music. You have to do proper soundproofing to convert the closet into a recording studio.
