How to soundproof a baby room? The best way to soundproof a baby room is to use a combination of materials, including heavy curtains or drapes, carpeting, furniture, acoustic panels and other barriers. Install double-pane windows with weather stripping around the edges and caulking in between the panes. 

You want your baby to sleep soundly and calmly. But, if the room is not soundproof enough, you might feel confused to work out this problem. Well, the solution is at hand! Check out this article for how to soundproof a baby room in several easy steps.

How to Soundproof a Baby room?

How to Soundproof a Baby room?

Use sound dampening materials such as acoustic panels on all walls, ceilings, and floors. Install double or triple pane windows for better insulation from outside noise. Install weatherstripping and caulking around windows to reduce the amount of sound that comes in through these openings.

Soundproofing the baby room can be done in a number of methods and techniques. The most effective way to soundproof a room is to use multiple methods in combination. 

1. Soundproof the Door

Soundproof the Door

A door can be a major source of noise. Soundproofing a door is an effective way to reduce noise in a baby room. Here is a list of ways to soundproof a door so that you can choose which method is best for your needs.

  • Attach Door Sweeps
  • Install weather stripping
  • Install door gaskets
  • Use Mass Loaded Vinyl (MLV)
  • Apply acoustic caulk or sealant
  • Hang drapes or soundproof curtains
  • Install Automatic door bottom

Attach Door Sweeps

One of the best ways to soundproof a door is by installing a sweep. A sweep is a rubber-like piece that fits between the bottom of the door and its frame, creating an airtight seal.

Install Weather Stripping

Another way to soundproof a door is to install weather stripping around the edges of the door. Weather stripping can be installed on the top, bottom and sides of the door. This will create an airtight seal that prevents sound from escaping or entering through cracks in your home’s structure.

Weather stripping comes in a variety of options including foam, rubber and felt materials.

Install Door Gaskets

Door gaskets are a quick and easy way to reduce noise coming through a door. Door gaskets are small foam or rubber strips, usually made of neoprene, that fit between the edge of the door and the frame.

The most common type of door gasket is called a weather stripping gasket, which is available at your local hardware store or home improvement retailer.

Use Mass Loaded Vinyl (MLV)

Mass-loaded vinyl (MLV) is a thick, heavy and dense type of soundproofing material. It is made of a double-sided mat of plastic fibers that are coated with an adhesive on one side. When installed, this adhesive is exposed and acts as the sound barrier.

Soundproofing the door with MLV is a great way to block out noise in the baby room. This method will work best on hollow doors, such as those made from particle board or fiberboard.

Apply Acoustic Caulk or Sealant

Acoustic caulk or sealant is a product that is both soundproof and waterproof. This means it can be used to insulate your door from both noise and moisture, making it an excellent option for use around doors.

Hang Drapes or Soundproof Curtains

Hang drapes or soundproof curtains on either side of the door. This will help keep noise from creeping into other rooms.

Install Automatic Door bottom

An automatic door bottom is a great way to keep noise from entering your home. This is because it seals the gap between the bottom of your door and the threshold. 

2. Soundproof the Floor

Soundproof the Floor

Soundproofing a floor is a good way to keep unwanted sounds from traveling through the floor and into the room (especially if it’s a baby room).

You might think that soundproofing a floor would be expensive and difficult, but it’s actually fairly easy and affordable, especially if you’re willing to do some of the work yourself.

The basic idea behind soundproofing a floor is that you want to cut down on the amount of noise transmitted through the floor by making it more dense than it was before. Here I have broken down all the ways so that you can choose what’s best for you.

  • Install Acoustic Underlayment
  • Use Acoustic Floor Mats
  • Install Decoupling Systems
  • Use Acoustic Sealant and Caulking
  • Attach Floating Floors
  • Use Resilient Channels

Install Acoustic Underlayment

Acoustic underlayment is a layer of material placed between the subfloor and the finished flooring. It can be made of many materials, including but not limited to carpet, rubber, and cork. This addition can help reduce sound transmission by damping vibrations that may otherwise travel from one floor to another through air gaps or crevices in walls and ceilings. Underlayment is an affordable option for those who want to minimize unwanted noise without spending too much money on fancy equipment (and it’s also easy to install).

Use Acoustic Floor Mats

Acoustic floor mats are a cheap and easy way to soundproof your floor. These rubber mats can be nailed down, so they won’t move around. They’re great for concrete floors and carpets alike, but they do come with one drawback: they may not look very nice in the baby room.

Acoustic floor mats are available in different sizes and colors, so you should be able to find something that works for the area where you want to install them.

Install Decoupling Systems

Decoupling systems are used to reduce the transfer of vibration between two surfaces. They are usually made up of thin plates or wedges that are placed between the two surfaces. The decoupling systems then absorb vibrations and prevent them from being transferred along a structure. When combined with resilient channels, which also help to reduce vibration, decoupling systems can work really well to soundproof your floor. You may have to hire the professionals to install decoupling systems.

Use Acoustic Sealant and Caulking

Caulking and sealant are a good way to soundproof your floor. They can be used on the subfloor, walls and ceiling. Sealant and caulking are applied to fill gaps in the subfloor, walls and ceiling that allow sound to pass through.

Subfloors are usually made of plywood or OSB (oriented strand board). These materials have gaps between each layer of wood fibers that allow sounds from below to pass through easily if not filled with sealant or caulking.

Attach Floating Floors

Floating floors are the best way to soundproof your floor. A floating floor is a type of subflooring installed over an existing floor and is made from wood, vinyl or composite materials. Floating floors are easy to install and can be done by a DIYer if necessary. The process involves attaching the surface material above the original subflooring with long screws through every joist in order to create an effective barrier between the two layers of wood.

Use Resilient Channels

Resilient channels are a simple, effective way to soundproof floors of a baby room. The channels can be cut to fit any size space and provide an additional layer of cushioning for your floors. If you have an area where there is excessive noise or vibration caused by machinery, this may be the best solution for you.

3. Soundproof the Windows

Soundproof the Windows

Windows can be a significant source of noise from outside. Soundproofing windows is a common way to reduce the sound transmission in the room.

It’s easy to do and doesn’t require any special skills or tools. You can use different methods to soundproof windows, depending on the type of window frame you have and the amount of noise coming through it.

  • Double-glazed Windows
  • Acoustic Glass (Double-glazed windows Alternative)
  • Use noise reduction Window insert
  • Caulk the Gap around the Window
  • Hang Drapes or Curtains

Double-glazed Windows

The most effective way to soundproof your windows is with double-glazed windows. Double-glazing works by sandwiching air between two layers of glass, which means that sound cannot pass through it.

In this way, your baby will not have to listen to the sounds of cars and trucks in the street.

Acoustic Glass (Double-glazed windows Alternative)

Acoustic glass is a type of glass that reduces noise. It is made up of two sheets of glass with a layer of air between them.

This means it can be used for double glazing, which involves placing one sheet of acoustic glass over another to make the soundproofing more effective.

Use noise reduction Window insert

This is a great option if you’re looking for something quick and easy. Window inserts are made of a special sound-absorbing material that can be purchased at any hardware store, but they’re not very thick.

They attach over your existing window using suction cups or Velcro, which makes installation pretty easy as long as you have basic DIY skills.

Caulk the Gap around the Window

Caulking around the window and frame is a great way to soundproof windows. Caulking can be messy, so make sure you wear gloves and cover any furniture in the room with plastic or drop cloths before applying caulk.

You should apply caulk to both sides of each joint between the frame of your window and its surrounding wall. You’ll also want to use high-quality caulking materials as low-grade caulks will crack over time due to temperature changes as well as impact from wind or hail storms.

Hang Drapes or Curtains

Another way to soundproof a window is to hang a curtain or drapes around the window. Curtains will absorb some of the sound, while drapes will absorb more of it.

If you want your curtains or drapes to be most effective at absorbing noise, choose heavy fabrics such as velvet or silk that are lined with cotton fabric.

4. Soundproof the Walls

Soundproof the Walls

Soundproofing the walls of your baby’s nursery is a great way to make sure that your baby will get a peaceful sleep.

The best way to soundproof a wall is by adding mass or acoustical sealant between the drywall and framing members. This may require cutting out sections of the drywall or framing members depending on how much mass needs to be added.

You can soundproof the walls using one of these methods or the combination of these methods.

  • Use Mass Loaded Vinyl
  • Install Resilient Sound Channels
  • Acoustic Panels
  • Drywall

Use Mass Loaded Vinyl

Mass loaded vinyl is a great option for those looking for an affordable, reliable way to soundproof their walls. It is relatively easy to install and can be used in conjunction with other soundproofing methods.

Mass loaded vinyl panels are sturdy, flat sheets of material that are installed vertically on the wall. The weight and density of these panels help them absorb more noise than foam.

Install Resilient Sound Channels

Resilient sound channels are thin pieces of plastic that are attached to the wall with a special adhesive. When the wall is hit, it will vibrate and dissipate the sound. This option is not as effective as other methods, but it is very easy to install.

Acoustic Panels

Acoustic panels are a great option for soundproofing. Acoustic panels are made of foam or fiberglass and can be used as a sound barrier, which will help to block sound from entering the room or leaving it.


Drywall is a common material used to soundproof walls. It has several advantages over other options, including that it’s inexpensive, easy to install and can be cut to fit any size wall.

Drywall works by absorbing sound energy. The thick layer of gypsum in the drywall absorbs both high and low frequencies, which reduces noise transmission through the wall.

Drywall is also able to absorb ambient noise from outside sources such as traffic or neighbors talking because it has air cavities between layers that act like an acoustic sponge for sound waves.

5. Soundproof Baby’s Crib

Soundproof Baby’s Crib

In order to soundproof a baby’s crib, you will need to use materials that will help block out any outside noise.

  • By purchasing a crib canopy. This type of material is designed to block out light, but it also helps reduce outside noise as well.
  • Using sound absorbing material such as blankets or pillows on all sides of the crib bedding.
  • Adding padding to the inside of the crib mattress.

6. White Noise Machine

White Noise Machine

If you want to create a calming environment for your baby, one way to do it is by using a white noise machine. 

White noise machines are designed to give off a consistent sound that masks other sounds. The idea is that the constant noise will mask the noises you don’t want your baby to hear, such as barking dogs, sirens, or someone talking loudly outside the room. 

This can help them get back to sleep when they wake up in the middle of the night.

7. Add more Furniture

Add more Furniture

You can reduce the amount of noise in your baby’s room by adding furniture that blocks sound, such as bookshelves, cabinets or curtains.

Adding extra pieces of furniture can help reduce noise from footsteps outside of the room. If you have solid walls between your baby’s room and others in the house, consider putting up bookshelves or shelving systems near those walls to help block out noise from others walking by.

Why would you Soundproof a Baby room?

Why would you Soundproof a Baby room?

The most obvious reason for soundproofing your child’s room is to protect them from loud and harmful noises. Moreover, if you have neighbors who like to play loud music late at night, then it would be wise to soundproof your baby’s room.

The most important thing to remember is that noise can be dangerous for your baby. It can cause hearing loss, disrupt sleep and even affect speech development. So it’s worth taking some precautions to block out the noise.

This will not only keep your child from being disturbed by the music, but also from being accidentally awakened by it as well.

Moreover, soundproofing will help keep harmful sounds out of their room so that they don’t have to hear things like lawn mowers and motorcycles when they’re trying to sleep or nap.

Additional tips for Outdoor Noise Reduction

Additional tips for Outdoor Noise Reduction

Landscaping techniques to create a natural barrier against noise

Trees, shrubs, and plants can act as natural barriers that absorb and block sound waves. Consider planting tall, dense foliage along the side of your home facing the noise source, such as a busy street or noisy neighbors. 

Evergreen trees or thick hedges can be particularly effective at reducing noise due to their year-round foliage and dense branches. Additionally, incorporating a water feature, like a fountain or a pond, can help mask outdoor noise with the soothing sound of flowing water.

Installing noise barriers such as fences or walls

Another effective way to reduce outdoor noise is by installing noise barriers, such as fences or walls. Solid fences made of materials like wood, vinyl, or metal can block sound waves and create a physical barrier between your baby’s room and the noise source. 

Make sure the fence or wall is tall enough and extends beyond the height of the windows of the baby room for optimal noise reduction. Additionally, sealing any gaps or cracks in the fence or wall can further enhance its effectiveness in blocking noise.

Using outdoor soundproofing materials or products

There are specialized outdoor soundproofing materials and products available that can help reduce noise from reaching your baby’s room. For example, outdoor acoustic panels or soundproof curtains can be installed on the exterior walls of your home to absorb and block noise. 

These panels are typically made of sound-absorbing materials, such as foam or fiberglass, and can be disguised with outdoor-friendly fabric covers. Another option is outdoor soundproofing blankets or barriers that can be hung on fences or walls to create an additional layer of noise reduction.

Choosing the right location for the baby room within the home

The location of your baby’s room within your home can also impact its exposure to outdoor noise. If possible, choose a room that is farther away from the noise source, such as a room in the back of the house rather than the front. 

Avoid placing the baby’s crib against walls that face the noise source, and consider using a white noise machine inside the baby’s room to mask any remaining outdoor noise.


The best way to soundproof a baby room is by installing acoustic panels and other sound dampening materials inside your walls and ceilings. Install heavy drapes or shades over windows that face busy streets or highways. Use double-paned windows to keep out noise from outside your house.

There are several ways to soundproof a room, and it all depends on what type of noise you need to block out. 

Soundproofing can be as simple as installing carpeting or adding drapes on windows, or as complex as building an entire room within your house.

This article will show you all the steps to soundproof your baby’s room and give your child a peaceful and enjoyable sleep.

Frequently Asked Questions (Soundproof Nursery/Baby room)

Should you soundproof a baby room?

Babies sleep better in a quiet environment, but if you live in a noisy neighborhood, soundproofing can help reduce the amount of noise your baby hears. If your neighbors like to play loud music late at night, then you should consider soundproofing your baby’s room.

The good news is that it’s not as expensive as you might think. There are plenty of cheap DIY options that’ll help block out annoying sounds from outside (and prevent the noise from getting through). 

How do I block out noise in my baby’s room?

The best way to block out noise in a baby’s room is by using soundproofing foam tiles or panels. They are designed to absorb sound waves so that they cannot travel through them. Place them around your child’s crib and they will muffle unwanted sounds coming from outside.

You can also choose a sound machine or white noise machine to block out unwanted sounds. It isn’t always necessary to turn it on all night long, only when you notice that your baby is getting upset over noises. 

Another option is to play music at low volume while your baby sleeps, which may help drown out other noises.

How do you soundproof a crying baby?

Make sure that your windows are well insulated and sealed properly so that air does not move between them and into the house. If there are gaps around pipes or wires, then try using caulk or foam insulation around these areas as well.

If there are other sounds coming from outside of your house that bother you, such as traffic noise or loud music from nearby houses, then consider adding more insulation in these areas as well. 

Insulating walls will also help reduce the amount of sound coming through them and make them more effective at blocking out noises.

Can you soundproof a room with blankets?

Yes, blankets are excellent for soundproofing because of their thickness and density. The thicker the material, the better it absorbs sound waves and prevents them from bouncing around the room. Blankets also help keep noise from leaking out of your room by absorbing any air that passes through them.
