The Best Soundproof Curtains – How Effective Are They?

Soundproofing is expensive and time consuming, however curtains are cheap and quick to put up.

By simply switching your existing curtains to soundproofing curtains (also known as sound dampening curtains) you can save considerable time and money.

Soundproof curtains are curtains which help to reduce sound transfer into your room.

However before you get over excited with dreams of turning your noisy city centre apartment into a soundproof box simply by hanging some fabric over your windows it is important to be honest about the impact that curtains can have on reducing sound.

Strictly speaking ‘soundproof curtains’ don’t exist, however acoustic curtains, designed to absorb sound and improve the acoustics of a room, do exist. The purpose of acoustic curtains is to reduce echo rather than to stop sound coming into a room.

However a good well insulated curtain can slightly reduce sound coming through your window by a few decibels.

Curtains are never going to make a huge impact to sound because they are not sealed and air can pass through and around them with ease.

Curtains aren’t great at soundproofing a room but they are very good at deflecting sound, if you have an echoey room and you want to reduce the echo then curtains are an excellent way to achieve that.

If you buy a good quality acoustic curtain and do everything you can to install it in a way which covers your window as effectively as possible then they can make a difference particularly with airborne background noises.

However if you live above a nightclub or next to a live music venue then soundproof curtains are unfortunately unlikely to make a noticeable difference, you should instead consider installing soundproof glass or soundproofing your window.

If you are still looking for a curtain which will help make those background noises in your home fade away a bit then have a look through some of our reviews of the best ones below.

How To Choose Your Curtain

Many of the best soundproofing curtains are sold on their ability to block light and trap heat in your room.

You will not find many curtains being sold as ‘soundproofing curtains’ but there are plenty that are listed as ‘insulated curtains’ or ‘blackout curtains’.

Fortunately curtains that are good at blocking sound, light and heat all share the same properties.

They are thick and very dense, they are oversized so that the window is amply covered and so that the curtain has pleats (which help deaden sound) and they are usually made from a material like velvet which helps block sound, light and heat.

Curtain Weight

Density blocks sound, unsurprisingly dense materials will weigh a lot!

Heavy curtains will block sound far more effectively than lighter curtains. This is because they are far more dense and are made from much more material meaning they have far more fibres to absorb and reflect sound.

Heavy curtains are often sold as insulated curtains which is why they are much thicker.Insulated curtains are particularly good at reducing low frequency sounds such as the sound of passing traffic.

The weight of a curtain is largely dependant on its size, however for a standard sized curtain a sufficient weight to block sound would be above 0.9kg / 2lb.

When installing a heavy curtain you will need to make sure that you have a strong curtain rail which is secured extremely well to the wall.

Curtain Materials

A truly soundproof curtain is something that doesn’t really exist, however sound dampening or sound absorbing curtains do exist.

While they won’t block out sound completely they will reduce reverberation and help minimise sound transfer.

Curtains which are best at doing this are made from materials which trap small pockets of air inside them.

The best materials for soundproof / sound- damping / sound-absorbing (or whatever you want to call them!) curtains are:

  • Velvet
    Velvet is put together in what is known as a pile weave structure.This structure consists of small loops which are all weaved together in one direction in loops.This means that velvet traps air (helping it better absorb and block sound) and it also makes it feel very smooth.
  • Kilo Serge
    Kilo Serge is what the giant curtains you get on theatre stages use, it is also commonly used in recording studios.Kilo Serge is made from densely packed wool which traps air making it great at absorbing sound.It usually only comes in black so is often used as a curtain lining for a more attractive looking curtain in domestic properties.

Curtain Size

Curtain size is important for dampening sound.

Bigger is always better with curtains.

Curtain Length

As a rough guide you should aim to get curtains which are up to 30cm (10 inches) longer than your window.

This will allow them to drape on the floor which will help to prevent sound from travelling through the air underneath your curtain.

If possible you should get curtains which are long enough to hang from the ceiling down to the floor, this will trap more sound.

Curtain Width

Your curtains should be wide, very wide!

The recommended width for soundproofing curtains is at least three times the width of your window.

This seems extreme however the width will allow your curtains to have lots of pleats in the curtains which will help to trap and absorb sound waves.

Curtain Rods & Mounts

It is very important to get the right curtain rods to help maximise the soundproofing potential of your curtains.

Your curtain rods should do two vital things:Be able to support the weight of your heavy curtains.

Allow the curtain to get as close to the wall as possible so that there are minimal gaps.

The best type of curtain rails are wrap-around rails.

Instead of being one straight these wrap around the window which means you can pull your curtains closed right up to the wall.

Most rods (with the exception of cheap plastic rods) will be able to support the weight of even the heaviest of curtains.

However it is vital that the rod is installed securely with deep screws and wall plugs to prevent it pulling away from the wall.

When installing your curtain rail make sure that you install it at least 10cm above the top of your window (or higher if possible) to help capture as much sound as possible.

These Deconovo curtains (why do very few curtain manufacturers use easy to pronounce names?) are made from thermally insulated polyester.

Polyester may seem like a strange choice for a soundproofing curtain as it is very lightweight and lacks density however polyester is very good at trapping air.

As the specially made hollow polyester fibres create thousands of very tiny air pockets with the curtain allowing it to absorb and deflect sound.

One additional benefit to having polyester curtains is that they do not attract dust or mites as most other curtains materials do, so these curtains are a great choice for anyone who suffers from allergies.

Available in two different sizes of 2.54 metres (8.3 feet) wide x 2.13 metres (7 feet) tall and 2.54 metres (8.3 feet) wide x 2.41 metres (almost 8 feet) tall two of these could easily cover a big bay window and one will be more than sufficient for a normal sized bedroom window.

The Deconovo curtain weighs in at 1.75kg and comes in a wide range of different colours including; beige, pink, navy blue, greyish white, chocolate, green and dark red.

With thousands of positive reviews on Amazon these are clearly a good choice for anyone with allergies who is looking for affordable sound dampening curtains.

If you’re looking for something that is affordable on a very tight budget then the Qinuo Home Alaska is a great choice.

This curtain is popular with students looking for a bit more privacy in their dorm rooms at a very reasonable price.The manufacturers claim that this curtain will reduce outside noise by 40%.

Not bad for a curtain which is primarily designed to block out light.

Made from 100% polyester (great for trapping air and absorbing sound) the Qinuo can also stop around 90% of light and ultraviolet light getting into your room.

The manufacturers state that the material is durable enough to last over ten years, which isn’t bad at all at this price.

These curtains come as a two panel set with each panel measuring 1.37 metres (4.5 feet) wide x 2.29 metres (7.5 feet) tall.Plenty of size to effectively cover windows of up to 2.4 metres in width – though if your window is this wide you are probably best off opting for a wider curtain as we recommend that your curtain is three times the width of your window to allow plenty of pleats to form which will help trap and absorb sound.

They can easily be attached to any preexisting curtain rail using the 12 inbuilt grommets which each curtain panel has.

These curtains come with two matching tie backs at no extra cost.

Absolute Zero – Velvet Soundproofing Curtain

Absolute Zero Velvet Blackout Home Theater Curtain Panel, 95-Inch, Stone Blue
  • Blocks 100-percent of intrusive light
  • Reduces unwanted noise and offers thermal benefits
  • Lush velvet fabric emulates real theater curtains

The Absolute Zero curtains get their name because they claim to let absolutely zero light through, a pretty bold claim right!

These curtains are very similar to the type of curtains you typically get in theatres and cinemas, they are designed to block all light and quite a bit of sound too when they are closed so that the audience has no way of seeing or hearing what is happening behind the curtain.

They are made from Velvet which is one of the best sound dampening materials due to the way it traps air inside allowing it to effectively absorb and deflect sound.

They are also very easy to take care of, you can simply throw them in the washing machine, tumble dry them, possibly give them a quick iron (if they need it) and then hang them straight back up!

The Absolute Zero is available in the following sizes:

  • 1.27 meters (4 feet) wide x 1.6 metres (5.2 feet) tall
  • 1.27 meters (4 feet) wide x 2.13 metres (7 feet) tall
  • 1.27 meters (4 feet) wide x 2.41 metres (8 feet) tall

And the following colours:

  • Cafe (an off cream colour)
  • Stone Blue
  • Chocolate
  • Black

For most small windows a couple of panels should sufficiently cover them, for larger bay windows 3 or 4 panels may be required for maximum sound dampening.

Moondream Soundproof Curtain

Moondream Sound Insulation Curtain, 3-in-1 Noise-Blackout-Thermal Insulation, Patented Technology,...
  • New Technology Curtains - 3 in 1 Solution: Soundproof, Blackout and Thermal Insulating - Tested in independant Laboratory
  • Reduce Outside Noise by four-fold, reaching a drop of up to 7 decibels
  • Insulate Your Home from the Outside - Helps to Reduce Home Heating and Cooling Costs

Moondream are one of the few brands that are trying hard to make curtains which are specifically designed to reduce background sound, they have put a lot into researching and developing curtains which perform very well.

Moondream have come up with a method of layering multiple fabrics to increase the density and weight of the curtains and help prevent sound coming through.

Layering many layers together rather than having one thick layer means there are several layers acting as a barrier to sound which also creates small pockets of air which further helps reduce sound transfer while improving opacity and thermal protection.

Their layers are:

  • Layer 1: A dense fabric layer to create a blackout effect.
  • Layer 2: An insulated sandwich layer in the middle of the curtain which helps insulate the curtain against sound and heat loss.
  • Layer 3: A dense brushed cotton layer.

In their tests Moondream found that a sound reduction of up to 7 decibels was achieved with this curtain.

For example if your window was letting through 70dB of sound and you then added the Moondream soundproof curtain the amount of sound let in would be reduced to 63dB.

Not a massive reduction but every little helps.

This curtain is sold in individual panels measuring 1.45 metres (4.8 feet) x 2.6 metres (8.5 feet), plenty big enough for even the tallest of windows.

Just don’t forget to buy two or three panels for bigger windows.

Remember the golden rule – your curtain should be three times the width of your window to allow for plenty of pleats to help minimize sound passing through.
