Sound Deadening Curtains: Do They Actually Work? See 5 That Does

To me, one of the most effective ways to soundproof a room is simply by using soundproofing curtains. Most of the time, you can easily find a nice one at a relatively low price (I got one for less than $50 before), and they are pretty easy to install.

These sound deadening curtains usually have the added benefit of blocking out sunlight, and some models even have insulation properties. What’s there not like about them? But seeing that some manufacturers make big bold claims, it is important to know, do soundproofing curtains really work?

Based on what I have encountered so far and some further research, I can say that sound deadening curtains are excellent at sound absorption, which means they are great at soaking up excessive echo from reverberating around the room. 

On the other hand, they might not be as effective at sound blocking, which means they still let in noise from the outside. 

With this knowledge in hand, is it sufficient to decide if you should be using soundproof curtains?

Certainly not, so stick around to the end to find out exactly if soundproof curtains are beneficial to you at all.

How do soundproof curtains work?

A soundproof curtain acts as both sound absorbers as well as sound barriers. This is the key feature that makes them soundproof.

The fiber content of the material of acoustic curtains gives it the ability to absorb sound. This polyester fiber has many great qualities such as high tensile strength and is resistant towards fire, abrasion and more. 

In fact, they have an NRC rating of between 0.8 and 1, which means they are highly sound absorbent.

Also, they have the ability to keep most of the sound out because of their thickness, hence acting as a barrier.

The material of soundproofing curtains vary depending upon the environment they’re going to be used in. 

Some common materials used are velvet, polyester, suede, satin, duck cotton canvas and quilted fibreglass. 

Sometimes, loaded vinyl or heavy vinyl are also used to increase the sound blocking capacity.

Did you notice that all these materials are porous in nature? 

The porous nature creates air traps. These air traps then transform the sound energy to heat energy.

Also, the ‘pile weave structure’ of the fabric of these curtains has loops in between. 

These loops help in trapping the sound.

Benefits of using soundproof curtains

Without going into the full details, I will highlight some of the key benefits associated with using sound deadening curtains:

  • Along with blocking sound, they also insulate light and temperature.
  • You can use them for eliminating the echo inside a room.
  • They are easy to install and remove.
  • They look as much decent as regular curtains.
  • When not needed, you can roll them and store very easily.
  • They are way more recyclable than regular curtains.

Difference between soundproof curtains and regular curtains

The main difference between acoustic and regular curtains is the material of which they’re made of. 

Fabrics like cotton, linen and silk are preferred for regular curtains. On the other hand, acoustic curtains are made up of velvet, polyester, satin etc. 

Regular curtains are mostly needed to get some privacy. So, they just have to be opaque and very less thick. While acoustic curtains need to be thick enough to block out sound and in some cases insulate a room. 

Fabric of regular curtains is tightly woven while the fabric of acoustic curtains is woven in ‘pile weave structure’. 

Sound reducing curtains are sometimes used in multiple layers to provide some extra sound insulation. Though you can do it with regular curtains too but there’s no need for it. I mean spending on multiple layers of curtains for no reason doesn’t make sense, right?

How to choose the right soundproof curtain?

A perfect soundproof curtain would be one that:

  • covers your wall neatly
  • blocks sound very efficiently
  • fits well with the overall home decor
  • easy to maintain
  • is durable
  • and fits your budget

You need to be quite careful when shopping though, as some regular curtains market themselves as soundproof curtains, when in fact they do not exhibit any of the characteristics of sound deadening curtains. 

One major giveaway is if the curtain is lightweight. Soundproof curtains are heavy, as that is the quality that sets it apart. So be sure to take into consideration the factors we discussed in this article.

Tips on choosing the right sound deadening curtain

I have a few suggestions for you when seeking out the right model for your home. I have found that incorporating these actions had helped me to use the curtains more effectively. 

Ensure the curtains are large enough to cover the window entirely

Make sure the sides are not left out as well by having extra few inches allowance on either side

The curtains need to be long enough to cover from your ceiling to the floor

Use ceiling mount curtain brackets instead of regular wall brackets or rods. This will bring your curtain closer to the ceiling and be more effective

Key features to look out for when buying soundproof curtains

1. Measurements: The first thing you need to figure out before buying a soundproof curtain is the measurement. Ideally, I recommend you to buy a curtain at least 10 inches longer than the window length. 

Also, it should be much wider than the width of the window. The target is to cover as much area of the wall as possible. This is because more area coverage means better sound insulation. 

2. Material of curtains: The material of curtains decides how much efficient it is going to be. The material should have a high percentage of fiber in it. Polyester, velvet and suede are some of the good sound insulators. I personally like velvet curtains as they fit better into the overall theme and look of my home.

3. Weight: The weight of the curtains is also an important factor that is often overlooked. More weight means more density which, in turn, makes them more effective. Heavier curtains are also able to keep away low frequency sounds, such as bass, better than the lighter ones. A 5 to 10 pounds weight would be enough for household needs. 

4. Other important features: 

  • You should choose ceiling mounts over wall brackets
  • Thickness should be at least 3 inches
  • Having a thermaweave layer would be a plus point
  • Energy smart curtains will also keep you warm in winters and cool in summers
