In this blog, we’ll explore the step-by-step process of soundproofing a room with blankets, so you can enjoy peace and quiet or record professional-quality audio in your own home.

Understanding Soundproofing and Sound Absorption

Understanding Soundproofing and Sound Absorption

Before delving into how to soundproof a room with blankets, it’s important to first understand the concepts of soundproofing and sound absorption.

Although the terms are often used interchangeably, they actually refer to two different techniques used to minimize the transmission of sound in a given space.

Soundproofing vs. Sound Absorption

Soundproofing refers to the process of preventing sound from entering or exiting a room. It involves creating a barrier that reflects or absorbs sound waves, preventing them from passing through. Soundproofing is typically used in spaces where sound needs to be completely blocked, such as recording studios, home theaters, or sound-sensitive rooms.

On the other hand, sound absorption refers to the process of reducing the amount of sound reflected within a room. This is achieved by placing materials that absorb sound waves, such as acoustic foam, on the walls, ceiling, or floor.

Sound absorption is commonly used in spaces where excessive echo or reverberation is a problem, such as concert halls, conference rooms, or recording studios.

Materials that Help in Soundproofing

There are several materials that can be used for soundproofing a room. Some of the most effective options include:

  • Mass Loaded Vinyl (MLV): MLV is a dense material that is specifically designed to block sound transmission. It is typically used as a barrier between walls or as a layer beneath flooring.
  • Acoustic Caulk: Acoustic caulk is a special type of sealant that is used to seal gaps and cracks in walls, ceilings, and floors. By filling these gaps, acoustic caulk helps to prevent sound from leaking through.
  • Soundproof Curtains: These curtains are made of heavy, dense materials that can help to block sound transmission. They are commonly used in home theaters or music studios.

How Blankets can be Effective for Sound Absorption

While blankets are not typically used for soundproofing, they can be effective for sound absorption. This is because blankets are made of soft, fibrous materials that can absorb sound waves. To use blankets for sound absorption, simply hang them on the walls or lay them on the floor.

However, it’s important to note that blankets are not as effective as specialized acoustic materials, such as acoustic foam or panels. Moreover, blankets may not be able to absorb lower frequencies of sound, such as those produced by bass instruments or heavy machinery.

Nonetheless, using blankets can be a cost-effective and easy way to improve the acoustics of a room.

When it comes to soundproofing a room, many people might not think to use blankets as a solution. However, blankets can be an affordable and effective way to reduce noise and create a more peaceful environment.

Following are the different types of blankets that can be used for soundproofing and their unique properties.

Regular Blankets

Regular blankets are the most common type of blanket used for soundproofing. While regular blankets are not specifically designed for soundproofing, they can still provide some level of noise reduction. The thicker the blanket, the better it will be at absorbing sound waves.

However, regular blankets may not be as effective as other types of blankets specifically designed for soundproofing.

Moving Blankets

Moving blankets, also known as furniture pads, are a type of blanket specifically designed for moving furniture. They are made from heavy-duty materials such as cotton or polyester and are designed to protect furniture from scratches and dents during transport.

Moving blankets are also effective at reducing noise due to their thick and dense construction. They are often used in recording studios and other environments where noise reduction is important.

Acoustic Blankets

Acoustic blankets, also known as sound blankets, are specifically designed for soundproofing. They are made from materials such as fiberglass or mineral wool, which are excellent at absorbing sound waves.

Acoustic blankets are often used in recording studios, home theaters, and other environments where noise reduction is critical. 

Weighted Blankets

Weighted blankets are designed to provide a sense of comfort and relaxation by mimicking the feeling of a warm hug. They are made from materials such as cotton or polyester and filled with plastic pellets or glass beads.

While weighted blankets are not specifically designed for soundproofing, their thick and dense construction can provide some level of noise reduction. They can be used in combination with other types of blankets to create a more effective soundproofing solution.

Preparing the Room for Soundproofing

Preparing the Room for Soundproofing

Soundproofing a room can be an effective way to block out unwanted noise, whether you’re trying to work from home or just looking for some peace and quiet. While there are many different methods for soundproofing a room, using blankets is a simple and affordable solution.

However, before you can start hanging blankets, you need to prepare the room properly. These are some important steps you should take before starting your soundproofing project.

Identifying the noise sources

The first step in preparing your room for soundproofing is to identify the sources of noise. This will help you determine where to focus your efforts and what type of soundproofing materials to use. Some common sources of noise in a room include traffic outside, noisy neighbors, and HVAC systems.

To identify the noise sources in your room, take some time to listen carefully and make note of when and where you hear the most noise. It can also be helpful to use a sound meter to measure the decibel levels in different areas of the room. Once you have identified the sources of noise, you can start to think about how to block or absorb the sound.

Sealing gaps and cracks

Another important step in preparing your room for soundproofing is to seal any gaps or cracks in the walls, doors, or windows. Even small gaps can allow sound to leak in or out of the room, reducing the effectiveness of your soundproofing efforts.

To seal gaps and cracks, you can use weatherstripping or caulking. These materials are easy to apply and can help to create a tight seal around doors and windows. You can also use acoustic sealant to fill any gaps in the walls or ceiling. This will help to prevent sound from traveling through the walls and into other rooms.

Removing or rearranging furniture

You should consider removing or rearranging furniture in your room to optimize your soundproofing efforts. Heavy furniture can help to absorb sound, but it can also block the path of sound waves and create reflections that make the room sound more reverberant.

To optimize your soundproofing, try moving furniture away from the walls and placing it in the center of the room. This will allow sound waves to travel freely around the room and be absorbed by your soundproofing materials.

You should also consider removing any unnecessary furniture or clutter from the room to reduce the amount of surface area that sound can bounce off of. By taking these steps, you can create a more acoustically neutral space that is easier to soundproof effectively.

Step by Step: Soundproofing with Blankets

If you’re looking for an affordable and easy way to soundproof a room, using blankets is a great option. Not only is it cost-effective, but it also allows you to add a touch of personal style to your soundproofing solution. Below is a step-by-step guide to help you soundproof your room with blankets.

Choosing the Right Type of Blanket

The first step to soundproofing a room with blankets is to choose the right type of blanket. Not all blankets are created equal when it comes to soundproofing. Here are a few things to keep in mind when selecting your blankets:

  1. Material: Look for thick and heavy blankets made from materials like wool, cotton, or polyester. These materials are great at absorbing sound waves.
  2. Size: Make sure the blankets are large enough to cover the entire wall or window you’re trying to soundproof.
  3. Weight: The heavier the blanket, the better it will be at soundproofing. Look for blankets that are at least 1.5 pounds per square foot.

Measuring and Cutting Blankets to Size

Once you’ve chosen your blankets, the next step is to measure and cut them to size. Here’s how to do it:

  1. Measure the area you want to soundproof and add a few inches to each side.
  2. Use scissors or a utility knife to cut the blankets to the desired size.
  3. If you’re soundproofing a window, make sure to leave enough room for the curtain rod or blinds.

Attaching Blankets to Walls

After you’ve cut the blankets to size, it’s time to attach them to the walls. Here are a few ways to do it:

  1. Use double-sided tape to stick the blankets to the walls.
  2. Install eye hooks and use bungee cords to hold the blankets in place.
  3. Use a staple gun to attach the blankets to the walls. This is a more permanent solution, so make sure you’re okay with leaving staple holes in your walls.

Covering Doors and Windows

To soundproof a room effectively, you’ll need to cover not just the walls, but also the doors and windows. Here are a few tips:

  1. Use a thick blanket to cover the door. You can attach it using the same methods as you would for the walls.
  2. For windows, use a heavy blanket or blackout curtains to cover them. Make sure the curtains or blanket are long enough to cover the entire window.

Layering Blankets for Improved Soundproofing

To achieve maximum soundproofing, consider layering the blankets. Here’s how to do it:

  1. Attach one blanket to the wall using the method of your choice.
  2. Attach a second blanket on top of the first using the same method.
  3. Repeat until you’ve achieved the desired level of soundproofing.

Combining Blankets with Other Soundproofing Materials

While blankets alone can do a great job at soundproofing a room, you can also combine them with other materials for even better results. Here are a few options:

  1. Use acoustic foam panels in addition to blankets to further absorb sound waves.
  2. Install a door sweep to block out sound from under the door.
  3. Use weather stripping to seal any gaps around doors and windows.

Maintaining Your Soundproofed Room

After taking the effort to soundproof your room with blankets, it is important to maintain it properly to ensure that it continues to function effectively. Below are some essential tips on how to maintain your soundproofed room.

Cleaning and maintaining the blankets

Regular cleaning and maintenance of the blankets is crucial to ensure that they remain effective in soundproofing your room. Over time, dust, dirt, and other particles can accumulate on the blankets, making them less efficient in absorbing sound. To keep your blankets clean, you can follow these steps:

  1. Shake the blankets outdoors to remove any loose debris.
  2. Use a vacuum cleaner with a soft-bristled attachment to remove any remaining dirt or dust.
  3. Spot clean any stains with a gentle detergent and a damp cloth.
  4. Allow the blankets to air dry completely before putting them back in place.

It is also important to note that some blankets may be machine washable, while others may require professional cleaning. Always check the care label on your blankets before washing them.

Monitoring for wear and tear

Regularly monitoring your soundproofing blankets for wear and tear is another crucial step in maintaining their effectiveness. Over time, the blankets may develop holes or tears, which can compromise their ability to absorb sound. To prevent this, you can:

  1. Inspect your blankets regularly for any signs of wear and tear.
  2. If you notice any holes or tears, patch them up immediately with a durable tape or fabric patch.
  3. If the blankets are beyond repair, replace them with new ones.

Replacing or upgrading blankets as needed

Lastly, it is important to know when it is time to replace or upgrade your soundproofing blankets. If you notice that your blankets are no longer effective in blocking out sound or if they have become too worn out to repair, it may be time to invest in new ones. Upgrading to higher quality blankets can also improve the overall soundproofing of your room.

When shopping for new blankets, consider the following factors:

  1. Material: Look for blankets made of materials that are dense and heavy, such as wool or polyester.
  2. Thickness: The thicker the blankets, the better they are at absorbing sound.
  3. Size: Choose blankets that are large enough to cover the entire wall or window.
  4. Style: Consider the aesthetic appeal of the blankets and choose ones that complement your room’s decor.

By following these tips, you can ensure that your soundproofed room remains effective in reducing noise pollution and creating a peaceful environment.

Other Affordable Soundproofing Techniques

While using blankets to soundproof a room is a great option, there are other affordable techniques that can also help you achieve a quieter space. In the following paragraphs, we are discussing some other effective methods to soundproof a room without breaking the bank.

Weatherstripping for doors and windows

One of the most significant sources of noise in a room is often air leaks through doors and windows. To reduce this noise, weatherstripping is an excellent solution. Weatherstripping is the process of sealing gaps around doors and windows to prevent air leaks.

This will not only reduce noise but also improve energy efficiency by preventing air from entering or escaping from the room.

To weatherstrip your doors and windows, first, identify the areas with gaps and cracks. Then, choose the appropriate weatherstripping material, such as foam tape, rubber, or vinyl. Cut the weatherstripping to the right length and attach it to the door or window frame using adhesive or nails.

Adding mass to walls with mass loaded vinyl

Another way to soundproof a room is by adding mass to the walls. Mass loaded vinyl (MLV) is a popular material for this purpose. It is a dense and heavy material that can block noise transmission through walls. MLV is usually sold in rolls that can be easily installed on walls.

To use MLV, measure the wall area that needs to be covered and cut the MLV accordingly. Then, attach the MLV to the wall using an adhesive or nails. It is also possible to add a layer of drywall over the MLV for extra soundproofing.

Using curtains and drapes for soundproofing

Curtains and drapes are another affordable option to soundproof a room. They can absorb sound waves and prevent them from bouncing off walls and surfaces, reducing noise levels. Thick and heavy curtains are the most effective for soundproofing.

To use curtains and drapes for soundproofing, choose the right fabric material, such as velvet or thick cotton. Hang the curtains or drapes from a ceiling-mounted curtain rod, covering the entire window or wall. It is also possible to add an extra layer of blackout curtains for additional soundproofing.


To soundproof a room with blankets, you can hang them on the walls using hooks or nails, and seal any gaps with adhesive strips. Layering multiple blankets can enhance the sound-absorbing effect.

As we conclude this discussion on how to soundproof a room with blankets, it’s important to weigh the effectiveness of this solution and consider its pros and cons. While using blankets can certainly help reduce noise levels, it’s important to recognize that it may not provide complete soundproofing in all situations.

Despite its limitations, using blankets for soundproofing can be a cost-effective and creative solution for those on a budget or looking for a temporary fix. It’s important to consider the specific needs of your space and the type of noise you are trying to reduce before deciding on a soundproofing solution.

The key to effective soundproofing lies in innovation and creativity. While blankets may work for some, there are numerous other solutions available, and combining various methods can lead to a more effective outcome.
