Do noise cancelling curtains work? In short – yes, they can reduce noise, but they will not completely block sound in the way true soundproofing does. Noise cancelling curtains work by absorbing and dampening sound waves, helping to reduce noise from outside and improve the acoustic comfort of a room. They are a cost-effective solution for people dealing with traffic noise, noisy neighbours, or general ambient noise, or anyone facing a persistent noise problem in their living or working space in a world filled with distractions.
At Persy Booths, we work closely with companies trying to solve everyday noise problems in offices and homes. While products like office pods offer a more controlled acoustic environment, many people first look to simpler solutions like curtains – so it’s worth understanding exactly how well they perform.
If you are considering noise reducing curtains, this guide will explain how they work, what they can and cannot do, and when they are the right choice.

How Noise Cancelling Curtains Reduce Sound

Noise cancelling curtains reduce noise by absorbing sound waves before they travel into a room. Instead of reflecting sound energy, dense fabric and multiple layers trap and dissipate it.
This process is known as sound absorption. When sound waves hit thick, tightly woven materials, part of the sound energy is absorbed rather than passing through or bouncing around the space. In fact, when sound waves encounter the dense materials of soundproof curtains, they convert sound energy into heat energy, thereby diminishing the overall sound level. This helps reduce echoes and lower overall noise levels. Reducing the transmission and reflection of sound is a key part of managing noise – which is exactly what acoustic curtains aim to do.
Unlike soundproof windows or structural sound insulation, curtains do not block sound entirely. Instead, they reduce noise by limiting how much sound enters and how much internal noise reflects within the room.

Materials Used in Noise Cancelling Curtains
The materials used in noise cancelling curtains are critical to how well they work. Most high-performing curtains are made from dense fabric, often layered with heavy material such as polyester blends or even mass loaded vinyl. Soundproof curtains are often made from heavy, thick materials like polyester, velvet, or suede.
Common features include:
- Multiple layers – thicker construction improves sound absorption
- Tightly woven fabrics – reduce the amount of sound passing through
- Heavy material – helps block sound more effectively than light materials
- Thermal insulation properties – also help regulate room temperature
- An effective soundproof curtain should be heavy, tightly woven, and run from ceiling to floor.
Heavier curtains provide better sound insulation because they add mass to the window area.
These curtains are made to balance sound reduction, thermal insulation, and energy efficiency, making them a practical addition to many spaces. The most effective options, often referred to as sound blocking curtains, use multi-layered construction and technical fabrics to maximise noise reduction.
Benefits of Sound Absorption
Sound absorption is a key factor in creating a quieter environment, and sound absorbing curtains play a vital role in this process. By absorbing sound waves rather than allowing them to bounce around a room, these curtains help minimise echoes and reduce overall noise levels. This is especially important in spaces where traffic noise, voices, or even the rumble of heavy machinery can disrupt daily life or sleep quality.
Sound absorbing curtains are particularly effective at tackling high frequency sounds, such as conversations or street noise, which are more easily absorbed by dense materials. However, with the use of advanced fabrics and materials like mass loaded vinyl, these curtains can also help reduce low frequency sounds, such as the deep vibrations from heavy machinery or distant thunder. The result is a significant reduction in both sharp and rumbling noises, making your space noticeably quieter.
The benefits of sound absorption extend beyond just noise reduction. By dampening sound, these curtains can improve sleep quality, boost productivity, and create a more peaceful atmosphere at home or in the office. Whether you’re trying to block out the sounds of a busy street or reduce internal noise, sound absorbing curtains made from dense materials offer a practical and effective solution for managing unwanted sound.
Reducing noise in the workplace
But do soundproof curtains work in the office? Cutting out external noise by using soundproof windows or indeed a material covering can make a big difference to the success of a business and the welfare and wellbeing of the people employed. Typical office workers frequently experience reduced concentration levels, with up to up to 60% of employees in a recent survey saying they were distracted by office noise. In high-decibel level environments, such as manufacturing, there is also a danger of hearing loss.

Do Noise Cancelling Curtains Work for Reducing Noise?

Do noise cancelling curtains work for reducing noise? Yes – but with realistic expectations. They can provide significant noise reduction, particularly for everyday sounds like traffic noise, voices, and general outside noise. However, they do not fully block sound.
In most cases, you can expect a noticeable drop in decibel level, rather than complete silence. Soundproof curtains can block anywhere from 20% to 50% of incoming noise. This can still make a huge difference to workday focus, comfort and – ultimately – sleep quality.
Noise canceling curtains work best when:
- The external noise source is present, such as a busy road or street activity
- The sound is mid to high frequency
- The curtains fully cover the window area and seal gaps
They are less effective when dealing with low frequency noises or structural sound transmission through walls, floors, or ceilings.
{{fact-2}}
Types of Noise They Reduce Best
Noise reducing curtains are particularly effective at handling certain types of sound:
- Traffic noise from cars and pedestrians
- Voices and conversations
- Higher sounds such as televisions or music
- General ambient noise from outside
These sounds are easier to absorb because they operate at higher frequencies. Acoustic curtains can absorb sound waves in this range more efficiently.
What Noise Cancelling Curtains Cannot Block
There is also a flip side. Noise cancelling curtains cannot fully block:
- Low frequency sounds such as bass or heavy machinery
- Vibrations travelling through walls or floors
- Internal noise from adjacent rooms: While curtains can help absorb some inside noise and reduce reverberation within a room, their ability to block internal or inside noise from adjacent rooms is limited.
- Loud, sudden sounds with high energy
Low frequency sounds pass through dense materials more easily. This is why soundproof curtains work only up to a point – they are not a complete soundproofing solution.
Where Noise Cancelling Curtains Work Best

Noise cancelling curtains work best in environments where the primary noise source comes through windows or open spaces. Placement and room layout play a major role in their effectiveness.
You will see the most benefit in:
- Rooms facing a busy road
- Spaces with single pane windows
- Areas where outside noise is the main issue (especially high frequency sounds)
- Rooms with hard surfaces that reflect sound
While soundproof curtains are effective at reducing noise, their dense materials and multiple layers can make a room darker. It's important to consider the impact on natural light when choosing and placing them to maintain a brighter, more comfortable environment.
In these situations, curtains can both reduce incoming noise and improve internal acoustics by reducing echoes.
Using Noise Cancelling Curtains in Bedrooms and Apartments
In bedrooms and apartments, noise cancelling curtains can improve sleep quality by reducing noise coming from outside.
They are particularly useful for:
- Blocking noise from a busy road
- Reducing disturbances from noisy neighbors
- Creating a quieter environment for rest
When installed correctly over the entire window and window frame, they can bring peace and noticeably reduce noise levels.
Noise Cancelling Curtains for Home Offices
For home offices, curtains can help create a more focused environment. They reduce outside noise and absorb internal noise, making it easier to concentrate.
This is especially useful for:
- Remote workers dealing with background noise
- Calls and meetings where clarity matters
- Reducing distractions in shared living spaces
However, they will not fully isolate sound – they simply reduce noise rather than eliminate it.
Noise Cancelling Curtains in Office Environments
In office settings, noise cancelling curtains can help manage echo and moderate noise levels. They are often used in open-plan offices to soften sound and reduce reflections.
They can:
- Reduce echoes and improve speech clarity
- Lower ambient noise levels
- Create more comfortable working conditions
Employers and office managers are increasingly aware of the commercial benefits of maintaining acceptable noise levels in the workplace. They understand that, while useful, curtains alone are rarely enough for busy offices. In many cases, more advanced acoustic solutions are needed, which has led to a dramatic increase in other noise control measures, such as the installation of soundproof booths.
Factors That Affect How Well Noise Cancelling Curtains Work
Several factors determine how effective noise cancelling curtains will be. Simply hanging curtains is not enough – performance depends on material, installation, and room conditions.
The most important factors include:
- Curtain thickness and density
- Proper installation and coverage
- Room layout and sound paths
Each of these plays a role in how much sound is absorbed or allowed to pass through.
Curtain Thickness and Density
Thicker curtains made from dense materials absorb more sound. Heavier curtains with multiple layers (such as blackout curtains) provide better sound insulation than lightweight options. Key points include:
- Dense fabric improves sound absorption
- Heavy material helps block sound more effectively
- Thicker curtains deliver greater noise reduction
Light materials, by contrast, allow sound waves to pass through more easily.
Proper Installation and Coverage
Installation is just as important as the material. Curtains must cover the entire window and extend beyond the frame to prevent sound leakage. Best practices include:
- Covering the entire window area
- Extending beyond the window frame
- Creating a tight seal around edges
- Sealing gaps where sound can enter
Without proper coverage, even the best soundproof drapes will underperform.
Room Layout and Sound Paths
Sound does not just travel through windows, but also moves through gaps, doors, and reflective surfaces. Factors that reduce effectiveness include:
- Gaps around doors and windows
- Hard surfaces that reflect sound
- Open layouts that allow sound to travel
To maximise results, it is important to consider the full path of sound within the room.
Energy Efficiency and Noise Reduction
Soundproof curtains do more than just reduce noise – they also enhance energy efficiency in your home or office. Thanks to their thermal insulation properties, these curtains help regulate room temperature by minimising heat transfer through windows. This means your space stays warmer in winter and cooler in summer, reducing the need for constant heating or air conditioning.
By installing soundproof curtains, you not only block outside noise but also create a more comfortable and sustainable indoor environment. The thermal insulation provided by these curtains can lead to noticeable energy savings, making them a cost effective solution for anyone looking to lower utility bills while enjoying a quieter space. For example, using curtains with strong thermal insulation properties can help prevent heat loss during colder months and reduce heat gain when it’s hot outside, all while keeping unwanted noise at bay.
Combining noise reduction with energy efficiency, soundproof curtains are a smart investment for homeowners and businesses alike. They offer a simple way to improve comfort, reduce noise, and save on energy costs – all with one practical upgrade.
Alternatives to Noise Cancelling Curtains for Better Noise Control

While curtains are useful, they are not always enough. In many cases, combining them with other soundproofing materials leads to better results. Here are three effective alternatives, each offering different benefits:
- Acoustic panels for internal sound control
- Acoustic booths for focused work
- Dedicated enclosed spaces for maximum noise reduction
Acoustic Panels and Soundproofing Materials
Acoustic panels are designed to absorb sound within a room. They are more effective than curtains at controlling internal noise and reducing echo. They work by:
- Absorbing sound waves across a wider frequency range
- Reducing reflections from walls and ceilings
- Improving overall sound quality

Acoustic Booths for Offices and Workspaces
Acoustic booths offer a more complete solution than curtains. They create enclosed spaces designed specifically to block sound and reduce noise levels. For example, a work booth provides:
- Sound insulation for focused work
- Privacy for calls and meetings
- A consistent, controlled acoustic environment
This is particularly useful in offices where ambient noise is constant.
When Dedicated Acoustic Spaces Work Better Than Curtains
There are situations where curtains simply are not enough:
- Open-plan offices with high noise levels
- Spaces with heavy machinery or constant noise
- Rooms requiring privacy for calls or meetings
In these cases, enclosed acoustic solutions outperform fabric-based options because they block sound rather than just absorb it.
Tips for Choosing the Right Curtains
Selecting the right soundproof curtains is essential for achieving significant noise reduction and creating a peaceful environment. Start by choosing curtains made from dense, heavy materials like velvet, suede, or those featuring multiple layers. Thicker curtains are more effective at absorbing sound waves and blocking noise than lighter, single-layer options.
Size matters too. Make sure your curtains cover the entire window area and extend beyond the window frame to prevent sound from leaking in around the edges. For maximum effectiveness, seal any gaps around the window frame, as even small openings can let noise through. Look for acoustic curtains specifically designed for sound absorption, as these are engineered to deliver significant noise reduction.
By focusing on dense materials, multiple layers, and proper installation, you can ensure your soundproof curtains provide the best possible results. Not only will this help block noise and absorb sound waves, but it will also improve sleep quality and create a more productive, quieter environment in your home or office.
