Do Soundproofing Blankets Actually Work?

Maybe you’re thinking about starting a recording studio. Or you just have annoyingly noisy neighbors, hence the thought of installing soundproof blankets.

If you want an efficient way to soundproof your house, a soundproofing blanket might be what you need.

Soundproof blankets are undoubtedly one of the most affordable and easiest ways to help absorb noise and reduce echo.

But does a soundproofing blanket really work?

Of course, soundproofing blankets work when you aim to dampen the sound. But they don’t block the sound 100%. They only act as sound absorbers.

That is why you need to set realistic expectations and realize that a soundproofing blanket won’t effectively block all the noise.

This article discusses soundproofing using blankets and what to consider when selecting a soundproofing blanket.

Do Soundproofing Blankets Actually Work?

Do acoustic blankets reduce noise?

Yes, soundproofing blankets work. A soundproofing blanket is a large piece of blanket used to deaden noise.

The blankets are made with special materials that act as sound absorbers.

You can lay the soundproofing blankets on the floor or attach them to the ceiling and wall to block unwanted sound. 

6 Ways to Soundproof With Blankets 

Attach Blankets to the Wall

You can use soundproof blankets in any room in your home. You’d just need to attach the blanket like you would a poster.

So, you either use lightweight tacks, or you can nail the blanket.

There are ways to achieve that:

  • Nailing the blanket at the center of the wall
  • Glue or tape it on the wall – you can use an industrial adhesive if the soundproofing blanket is heavy
  • Use mounting putty to tack it
  • Install curtain tracks, hang it on tall furniture, or you can even suspend it on a curtain rod

The most permanent option is nailing the blanket on the wall in all these options. Thus, if you choose this method, you’ll need to push the nail into the wall. 

Hang the Blanket Over Your Door

Doors are notoriously difficult when soundproofing, though you can use methods to succeed in it. Numerous doors have large gaps that allow air and sound to penetrate.

Still, soundproofing a door should be as easy as soundproofing all other areas. 

So, you can do the following:

  • Drape the blankets on the door
  • You can also use glue or nails
  • If you intend not to open the door, opt to fix the blanket with nails around the wall
  • You may choose to use curtain holders where you can hang the blanket

Nailing or gluing the blanket is the best option, only that you need to make sure the blanket is larger than the door.

Have extra blankets on the floor, sides, and the top part.

Use Blankets to Cover Windows

You can use soundproof blankets to soundproof your windows when all else fails. Therefore, you can choose to hang them like you would curtains.

Like always, it’s easier to hang up the blanket if it comes with grommets. 

Cover as many windows as possible to achieve the most sound-canceling experience.

Also, if your windows aren’t completely sealed, cover them entirely using the blanket and together with the surrounding walls. 

However, if you appreciate some little sun in the room, this is, of course, not the best way to soundproof your windows.

Alternatively, check out other different ways to soundproof your windows before you settle on using blankets. 

Still, choosing to temporarily keep the blankets if you’re recording a podcast, for example, does some magic to the sound quality.

Soundproofing Floors and Ceilings

Honestly, we don’t recommend using blankets to soundproof the floor and ceilings. It’s more difficult to nail a blanket on the ceiling than installing foam panels or other suitable methods. 

Similarly, you may use other effective ways to soundproof the floor other than laying the blankets down.

Well, laying the blankets on the floor gets you into the picnic mood, but that is certainly not what you intend to achieve.

So, before turning your house into what it’s not, you might want to try other ceiling and floor soundproofing options. 

Place Blankets Over Other Appliances

How to soundproof a room cheaply using blankets

Some people might want to cover their loud appliances in their homes.

However, you should approach this with caution because some appliances, especially heating appliances, may not take this too well. 

Still, you can cover appliances such as mini-fridges, laundry machines, and dishwashers. Therefore, you should unceremoniously lay the blanket or create some aesthetics around it. 

If you wish to muffle a laundry machine’s vibrations, you can perform the following:

  • Spread the blankets on your floor
  • Place the laundry machine at the center of the blanket
  • Tape blankets to cover the machine’s sides
  • Place another blanket so that it hangs on the back and front 
  • During laundry loading, roll up the top blanket

Cover Your Furniture

Finally, you all know that any hard surface allows the bouncing of sound waves.

If you intend to improve your room’s sound quality with a grand piano or a hardwood table in it, you should opt to cover them. 

As with the above steps, using a blanket eases the noise. 

However, having a blanket on your table isn’t exactly cute. So, you need to use an attractive table cloth or find attractive blankets.

Additionally, you may want to cover your leather sofas because it causes more echoing than softer material.

Do Soundproof Blankets Block Sound?

Much like all other methods used in noise cancellation, soundproof blankets don’t absorb 100% of the noise. Instead, the blankets deaden or muffle the sound to manageable levels. 

Of course, there will be a noticeable change as the sound bounces off up to 80%. 

For better effects, you should try pairing the soundproofing blankets with other noise cancellation products, such as soundproof curtains.

Why? Because the curtains make the space as noise-free as possible. 

When Should You Use A Soundproofing Blanket?

So, when is it a great idea to use a soundproofing blanket?

Soundproofing blankets are suitable for areas with plenty of hard surfaces and minimal furniture to absorb sound, leading to harsh, loud noise.

For example, a gymnasium is loud due to the noisy equipment and people talking. Thus, soundproofing blankets make it easier to muffle the noise.

Are you trying to do a recording? Maybe you’re using a multipurpose room where soundproofing permanently isn’t feasible.

You may choose to nail soundproofing blankets on the walls instead. 

Remember, the more gaps you get to cover with the blankets, the more you’ll manage to dampen the noise.

Selecting a Good Quality Soundproofing Blanket

Sound blankets for soundproofing room


Look for a design that suits your needs. There are different designs for soundproof blankets, and they all have different noise-deafening capabilities.

For instance, if you work in an environment that needs to be extremely quiet, you need a soundproof blanket with acoustic capabilities, hence blocking even the lowest of sounds.


It’s no surprise that the thicker the blanket, the better the soundproof blanket can absorb noise. The sound has more layers it needs to penetrate to escape the room.

Therefore, a thicker soundproof blanket is suitable in most situations.


We use grommets to hang the soundproofing blankets on the rods and walls. But, not all soundproof blankets have them.

That said, the blankets that have them are easier to hang and manage because you can slide them on the rod they’ve been installed on if need be.

However, it’s recommended that you buy the blankets without the grommets, then you can install them yourself.


When choosing an acoustic blanket, cheaper isn’t better! Generally, the cheaper the blanket, the poorer the noise-absorption.

That said, you can still find cheaper blankets with a great noise cancellation capability. 


Do Blankets Make Good Soundproofing?

Yes, blankets make good soundproofing. Using a blanket is among the best and most affordable options to help absorb noise and reduce echo.

As long as the blankets are dense enough, they ultimately do the trick.

If you have soundproofing blankets made with the appropriate material, they work well when used correctly.

For example, an acoustic blanket may not dampen all the noise, but it greatly reduces it. 

How Much Do Sound Blankets Reduce Noise?

The soundproofing blanket noticeably reduces noise up to 80%. Soundproof blankets kill off the echoes and reverberation in the soundwaves.

Therefore, soundproof blankets can’t cancel 100% of the noise.

Do Heavy Blankets Block Sound?

Yes, because the thicker and heavier the blanket is, the more sound it blocks.

Other than the area they cover, another critical aspect of the soundproof blanket is its thickness and heavyweight.

Final Thoughts

Hopefully, this article has given you clues on using blankets to soundproof your space. Finding a way to quiet the noise makes a huge difference in the quality of life.

Soundproofing is especially useful to podcasters, musicians, or anyone who wants to benefit from soundproofing their space.

If you’re low on cash to spend on a remodeling project, using a soundproof blanket helps deaden the noise.

A soundproofing blanket is affordable, and when it absorbs the sound waves, the noise reduces to acceptable levels.
