Do Curtains Absorb Sound

BY |

Yes, curtains can absorb sound to some extent, contributing to noise reduction within a room. Heavier, thicker, and denser curtains generally absorb more sound than thin ones. The material of the curtain also affects its sound absorption capacity; for example, velour or velvet curtains are usually better at sound absorption compared to those made from lighter materials like cotton or polyester.

Moreover, the way the curtains are hung can influence their sound-absorbing capacity. Curtains hung in pleated folds will have more surface area to absorb sound waves compared to curtains hung flat.

However, it’s important to note that while curtains can help reduce echo and improve acoustics, they aren’t as effective as specialized soundproofing or acoustic treatments such as foam panels, bass traps, or diffusers. If you’re looking for substantial sound reduction or soundproofing, you might need more professional and dedicated solutions.

How to soundproof a room with curtains


Installing heavy, noise-reducing curtains can help soundproof a room. Choose lined curtains made from densely woven fabrics like velvet, cotton, fleece, or wool for optimal noise absorption. Hang floor-length curtains that completely cover the window with generous overlap when closed. For maximum effect, install two sets of curtains per window – heavier inner curtains to dampen sound, and lighter outer curtains for decoration and additional muffling.

Add curtain rods that extend well beyond the window frame to eliminate gaps. Finally, ensure curtains form an airtight seal against walls when drawn to prevent noise transfer. Properly installed soundproofing curtains combined with acoustic insulation can significantly reduce noise in a room.

Curtains as soundproofing tools

Curtains can indeed act as sound-absorbing tools, helping to create a quieter environment. The thicker and heavier the curtain material, the more sound it can absorb, reducing echo and noise levels in a room. Special soundproof curtains are designed with multiple layers of fabric to maximize sound absorption. However, while they can dampen noise, curtains are not as effective as other soundproofing methods for completely blocking sound.

Best fabrics for sound absorption

Curtains can contribute to noise reduction within a space. The effectiveness of sound absorption largely depends on the fabric type. Heavier, thicker, and denser fabrics like velvet, suede, or tapestry are considered the best for sound absorption. They efficiently trap sound waves, preventing them from bouncing off hard surfaces and reducing echo. Therefore, investing in quality, heavy-weight curtains not only enhances your interior design but also improves your room’s acoustics.

Curtains’ Effectiveness in noise reduction

The fabric and thickness of the curtain play significant roles in this function. Heavier, denser curtains tend to absorb more sound waves, thereby reducing the level of noise. However, while curtains can help minimize echo and background noise, they may not completely block out loud, penetrating noise. For optimal sound absorption, specially designed soundproof curtains are recommended.

Soundproofing: curtains vs. other materials

Their effectiveness is often less than other dedicated soundproofing materials. Curtains, especially thick and heavy ones, help reduce echoes and dampen sound to a certain extent. They are often used in conjunction with other solutions for a more comprehensive approach to soundproofing. It’s important to note that while they can help lessen noise, curtains alone may not be sufficient for significant soundproofing needs.

Positioning curtains for sound absorption

Positioning curtains for sound absorption is an effective strategy to minimize noise levels in a room. Curtains, especially dense or layered ones, can absorb sound waves, reducing echo and background noise. They act as a soft barrier that absorbs and diffuses sound, rather than reflecting it like hard surfaces do. Therefore, positioning curtains around a room, or hanging them strategically in front of windows or doors, can significantly enhance the acoustic qualities of a space, creating a quieter, more peaceful environment.

Science of sound absorption

In the science of sound absorption, curtains play a significant role due to their fabric and thickness. They can absorb some degree of sound, especially high-frequency noises, and reduce echo within a room, improving the acoustics. The denser and heavier the fabric, the more effective it is at absorbing sound. However, they are not as effective as specialized acoustic materials. The sound absorption capability of curtains contributes to noise reduction, essential in creating quiet and comfortable indoor environments.

Soundproofing techniques for windows

While curtains do not entirely block sound, they absorb some of it, thereby reducing the overall noise levels. Soundproofing curtains are made of dense, heavy, and thick materials that can absorb sound waves more effectively. They are an affordable and visually pleasing option to reduce echo and decrease external noise intrusion, making them a popular choice in soundproofing techniques for windows.

Noise reduction with blackout curtains

Blackout curtains can play a significant role in sound absorption, enhancing noise reduction in a room. These curtains are designed with thick and often multi-layered fabric, which effectively absorbs and reduces incoming noise, making them ideal for bedrooms, home theaters, or any space where noise reduction is desired. While they may not completely block out all noise, the use of blackout curtains can significantly lower the intensity of outside sounds, contributing to a quieter and more serene environment.

Acoustic properties of curtain materials

Curtains can absorb sound this is largely dependent on the material and thickness of the curtain. Heavier, thicker curtains made from dense materials like velvet or wool are more effective at absorbing sound waves, hence reducing noise levels. They work by preventing the sound waves from bouncing off hard surfaces, instead absorbing and dampening the noise. Therefore, curtains can play a significant role in improving the acoustics of a space.

Layering curtains for better sound absorption

Layering curtains is an effective method to improve sound absorption in a room. Curtains, especially those made from thick, dense materials, do absorb sound waves, thereby reducing noise levels. By layering curtains, the thickness of the material is increased, enhancing the sound-absorbing capacity. The layered curtains work by trapping the sound waves, preventing echo, and reducing the sound that passes through. Therefore, for those seeking a quieter environment, using multiple layers of curtains can be a simple yet effective solution.

Do Heavy Curtains Reduce Noise?

Heavy curtains here on Amazon!

When you mention a soundproof curtain to anyone, they will have one common imagination: they are heavy. Well, this isn’t a coincidence.

Heavy curtains have a higher ability to reduce noise than thin, light ones.

When you want to get a soundproof curtain, you will always find a denser one. The heaviness serves as the best way to block sound waves from entering your room.

The main reason for the heaviness in sound-blocking curtains is the extra later between the curtain fabrics. For a curtain to be soundproof, there have to be sound-blocking materials placed in them.

Clothing materials or vinyl materials are the commonly used materials. These materials handle the heaviness and high density. Dense curtains can block noise three times more than ordinary curtains.

The heavy curtain will also reduce noise depending on some other factors. These include;

Length- the longer the curtain, the more the sound it can absorb. Longer curtains can cover up the entire window entirely and thus block any passage the sound may use to enter the room.

 A longer curtain will also provide a larger surface area to cover the window and thus absorb the sound more effectively than the short curtains.

When you want to reduce the noise in your house ideally, you will not just need a heavy curtain. A more prolonged and heavy curtain will be the best deal.

Material- thicker curtains will absorb more sound than thinner lighter curtains. However, even when buying a thick soundproof curtain, consider the material used to make it.

Thicker curtains made of Suede and velvet are more efficient for absorbing sound than other materials. They contain microfibers that absorb more sound waves and thus more sound.

Width and style- the width and style of the soundproofing curtain will also help you identify the best curtain to block unwanted sound.

A wider curtain will block all the sound waves from penetrating the window and finding their way into the house.

The style will also determine how effective your curtain will be. A curtain with pleats is heavier and thus prevents more sound.

The creases on the window seal also help in reflecting the sound waves.

How Much Noise Do Curtains Reduce?

Many people often ask the extent to which the curtain can help in blocking the sounds. To understand how much noise curtains can reduce, we must first understand the terms used to rate soundproofing materials like walls, curtains, and windows.

This will then help us to understand how much sound a curtain can reduce.

Sound transmission class (STC) is a rating of how well the material in question can eliminate air-borne sound. This rating will tell you how much decibel noise deduction you will get.

STC ratings of up to 35 are possible for the highest industrial quality soundproof drapes. Unless you want to spend a lot of money to remove the noise altogether, you’ll have to settle with living room drapes with a lower STC rating.

A genuinely good set of curtains will have an STC rating of up to 15, but you will most likely get between 5 and 10.

This may not seem like much at first, but your perception of changes in decibel levels may affect how much noise is reduced.

The more layers of noise-canceling materials you place between yourself and the problem, the lower the decibel levels.

Are There Curtains That Reduce Noise?

Yes, acoustic curtains do play a significant role in noise elimination. Acoustic curtains have been explicitly designed to reduce noise.

They do so by absorbing sound that travels through walls, doors, and windows, among other areas.

 Acoustical curtains perform best when they are not stretched taut, therefore allowing them to “fold” so that they are at least the width of the window or opening plus one-third while placing them.

Install acoustical curtains such that they overhang rather than just touch the margins of the window or aperture. For example, when hanging acoustical curtains, make sure they extend at least a foot past the window frame on both sides.

How Much Do Curtains Help With The Noise?

Curtain vary in terms of how much noise they can prevent. A thick curtain will prevent more noise as compared to thin, light ones.

To add to that, long curtains with a broader width will block more sound than shorter curtains with less width, even if they are made of the same material.

Most soundproof curtains have an STC of about five to ten. With this sound transmission class, these curtains can reduce noise significantly. You won’t hear a high irritating noise in your house.

Do Blackout Curtains Help With The Noise?

Blackout curtains are thick, dense curtains with a backing material traditionally used to keep light out of homes via windows.

They are an excellent choice for noise reduction or even soundproofing because of their density.

Expect blackout curtains not entirely to eliminate noise, but they may lower noise levels by up to 40%, which is quite substantial.

A 40% noise reduction might make the difference between irritating noise and noise you don’t even notice.

When you hang those heavy curtains, don’t expect them to immediately function as sound barriers and keep the bustle at bay. A curtain cannot be entirely soundproof, but it may significantly reduce or attenuate sound.

While hanging these heavy curtains, don’t expect them to function immediately as complete sound barriers to keep all the hustle and bustle at bay. A question often asked is: “Do curtains absorb sound?” The answer is yes, they do, but they cannot be entirely soundproof. While they do absorb sound, they may only significantly reduce or attenuate it. You may expect a muffling effect that will help to make your home as quiet as you want. However, the fabric’s structure and form allow some sound to escape. These soft, fluffy materials can absorb sound to dampen it, not fully block it. Despite this limitation, soundproof curtains can be quite beneficial. Their combined effect of aesthetic appeal and practical sound absorption makes them a beautiful and functional choice for any home or business.
