Unwanted noise is one of the biggest causes of stress, distraction, and reduced productivity in modern working spaces. Whether it's chattering colleagues, digital bleeps or the bangs and crashes of everyday office life, it all builds up. If you want to reduce unwanted noise, understanding the best soundproof materials is an essential first step to creating a calm, peaceful environment.
At Persy Booths we know all about this - and we visit many noisy offices. We also speak to many customers – when we can hear them, that is – about how to create a more peaceful working environment. One thing they always tell us is that there is a balance between achieving noise reduction and not overspending. So let's dive in and look at the best soundproofing materials of 2026, explaining how they work and where they’re used, while offering practical advice on how to choose the right soundproofing solution for your needs. (Spoiler alert: they're not always the most expensive solutions!)

What Is Soundproofing?
Soundproofing is the process of reducing or blocking the transfer of sound waves between spaces. When sound energy travels through air or solid materials, it creates vibrations that we perceive as noise. The aim of soundproofing is to either absorb sound, block its transmission, or both.
Soundproofing materials come in many forms – from dense materials like mass loaded vinyl to porous, sound absorbing materials like acoustic foam or mineral wool. These materials work by targeting either airborne noise (voices, TV noise, music) or impact noise (footsteps, doors closing, furniture movement).
Research shows that well-designed sound insulation can improve comfort, reduce stress, and enhance focus in workplaces. As an added bonus, modern materials often combine excellent sound absorption with thermal insulation, creating environments that are not only quieter, but also warmer and more energy efficient.
Choosing the right approach depends on the space, budget, and the kind of unwanted sound you want to manage.
Methods of Soundproofing
There are three main soundproofing methods used in modern design: insulation, decoupling, and absorption. Each tackles a different type of sound transmission and contributes to overall acoustic performance.
Insulation
Insulation adds mass to walls, ceilings, and floors to block the passage of sound vibrations. Materials like acoustic plasterboard or acoustic mineral wool prevent airborne and impact noise from travelling between rooms.
These sound insulation materials are particularly effective in shared walls, music studios, and recording studios, where low frequency sounds need extra control. By increasing density and sealing gaps with acoustic sealant, you can dramatically reduce sound transmission and create more effective acoustic insulation.
Decoupling
Decoupling involves separating structural layers so that sound vibrations can’t pass easily from one surface to another. This technique is often used in stud walls, ceilings, or concrete floors where impact noise can otherwise travel freely.
Decoupling works because it breaks the mechanical connection between two surfaces. For example, resilient channels or floating floors isolate the soundproofing system, allowing each layer to move independently. The result is effective sound insulation with less sound transfer and sound leakage between rooms.
Absorption
Absorption focuses on soaking up sound energy rather than blocking it. Porous materials like acoustic foam, acoustic panels, and acoustic curtains trap sound waves, converting them into small amounts of heat.
This is vital for improving sound quality inside a room, especially in music rooms, offices, or soundproofed office booths like the Persy One. Good sound absorbing materials reduce echo, reverberation, and external noise, helping to create a clearer and more comfortable acoustic environment.
15 Best Soundproof Materials
Below are 15 of the best soundproof materials available in 2026, explaining what each is for, how it works, and where it’s used.
1. Mass-Loaded Vinyl (MLV)

Where are they used? Offices, team meeting pods, and auditoriums.
4. Acoustic Mineral Wool
What is it for? Insulating against both airborne and impact noise.
How does it work? Its fibrous texture disperses sound energy and improves thermal insulation.
Where is it used? Behind stud walls and suspended ceilings.
5. Acoustic Plasterboard
What is it for? Wall soundproofing and ceiling upgrades.
How does it work? Its high mass core blocks sound transfer effectively.
Where is it used? Homes, schools, and commercial offices.
6. Acoustic Sealant
What is it for? Preventing sound leakage through small gaps.
How does it work? Remains flexible, maintaining an airtight barrier that stops airborne sounds escaping.
Where is it used? Between plasterboard sheets or around sockets and frames.
7. Closed-Cell Foam
What is it for? Reducing impact vibrations.
How does it work? Compresses and decompresses, dissipating impact energy.
Where is it used? Floors and structural panels.
8. Acoustic Underlay
What is it for? Minimising impact noise on acoustic flooring.
How does it work? Adds cushioning that absorbs footfall energy.
Where is it used? Beneath laminate, vinyl, or timber floors.
9. Acoustic Curtains
What are they for? Reducing external noise and reflections.
How do they work? Heavy, multilayered fabrics absorb and block airborne noise.
Where are they used? Homes, theatres, and music studios.
10. Soundproof Drywall

How to Soundproof Walls
When learning how to soundproof a wall, the key steps are preparation, layering, and sealing. The most effective approach combines several materials for blocking sound and absorbing reflections:
- Add acoustic insulation inside existing stud walls.
- Apply mass loaded vinyl or soundproof drywall for density.
- Seal all gaps with acoustic sealant to reduce sound leakage.
- Use foam panels or acoustic wall coverings for aesthetics and improved sound quality.
This layered method provides effective soundproofing solutions that can significantly lower noise levels, whether from noisy neighbours or adjacent rooms.
How to Soundproof an Office
While noise control is perhaps most associated with industrial settings, office noise can significantly impact productivity by reducing concentration levels. Noise control in the workplace is a topic that is formally regulated in most countries, such as the Environmental Protection Agency (EPA) in the US. No wonder businesses are increasingly investing in sound insulation to improve wellbeing and focus.

Soundproofing an office requires balancing privacy, productivity, and cost. Here’s how to soundproof an office or other workplace areas:
- Use acoustic panels and acoustic ceiling systems to control echo.
- Install acoustic underlay or acoustic flooring to reduce impact noise.
- Add acoustic curtains or acoustic plasterboard to block airborne sounds.
- Choose soundproofing products that integrate with HVAC and lighting systems for seamless design.
Many Persy Booths clients address these challenges by using modular pods like the soundproof phone booth for solo work, the two person phone booth for small meetings, or the team meeting booth for collaborative sessions – all designed to complement good sound control rather than overcomplicate it. Alternatively, the work booth offers a focused environment for individual productivity. Products like these combine effective sound insulation with compact, stylish design – proving that you don’t need to overspend to achieve acoustic comfort. (It's also worth mentioning that we sell direct, so you don't pay expensive reseller mark-ups either).
