Acoustic Absorption Data
The chart below shows the sound absorption coefficient of our standard acoustic foam across the frequency spectrum. As thickness increases, absorption performance improves — particularly in the lower mid-frequency range. For low-frequency absorption, we recommend pairing acoustic panels with bass traps in room corners.
If you need detailed acoustic performance data for a specific project or specification document, please contact our team and we will provide the full data sheet.

Acoustic Foam Frequently Asked Questions
Over 20 years of supplying acoustic foam means we've heard pretty much every question going. Here are the ones that come up most often, but if yours isn't here, just get in touch and we'll give you a straight answer.
Our customers range from YouTube creators and voiceover artists to professional sound engineers, musicians and recording artists. If you work from home and need a bit more privacy on calls or Zoom meetings, we can help with that too. See our guide on how to make a portable sound isolation shield.
What is Acoustic Foam?
Acoustic foam is an open-celled foam designed to absorb sound energy rather than reflect it. When sound waves hit a hard, flat surface they bounce back, that's what causes echo, flutter echo and the kind of hollow, reverberant sound that makes a room feel acoustically problematic. Acoustic foam breaks that cycle by trapping the sound waves in its open-cell structure and dissipating the energy before it can bounce.
It's worth knowing that acoustic foam treats sound, it doesn't block it completely. If you're trying to stop noise travelling between rooms or reduce sound escaping a space entirely, you'll need a combination of mass (dense materials in walls and floors) and acoustic treatment. But for improving the quality of sound within a room, which is what most of our customers need, acoustic foam is exactly the right tool.
It's used on walls, ceilings, doors and even inside speaker cabinets. It comes in flat sheets, convoluted (egg-crate) profiles, tiles, and self-adhesive panels depending on your application. If you're not sure which format suits your project, get in touch and we'll help you figure it out.
What types of acoustic soundproofing foam do you supply?
Here at eFoam, we supply several different acoustic foam types and can even provide custom soundproofing foam orders for you. Let's explore the different types of acoustic foam supplied by eFoam.
Tiles & Self Adhesive Panels
Tiles & Self Adhesive Panels: We make and stock two different sizes of acoustic foam soundproofing tiles that are available in a flat chamfered or convoluted design. We also supply large self-adhesive acoustic foam panels which are available either as flat or convoluted. If you require soundproofing with a high fire rating, try our Pyrosorb-S class 0 tiles. We also recommend adding bass traps in each corner of your room.
Bass Traps
Bass traps: The purpose of bass traps is to control acoustics and any reverberation in studios, mastering suites, home theatres or other rooms where the quality of sound is critical. Our bass traps are exceptionally effective at controlling particularly low-frequency reverberations that left to themselves would be problematic due to being long sound waves that are part of the audible bandwidth.
Professional Sonic Acoustics
Professional Sonic Acoustics: Our Sonic range of acoustic products are manufactured in the UK to exacting British standards complying with UL94 HF1 Classification. This foam can significantly improve the quality of sound in any environment. It works particularly well with the high-frequency region. These are designed for use on walls, ceiling and can be installed using our spray adhesive. They are typically used in recording studios, suites, offices, churches and home theatres.
Acoustic Foam Cut to Size
Acoustic foam cut to size: We can cut our acoustic foam to any size that you need. No matter what you're looking for, we can help. If you're looking for acoustic soundproofing for particular situations and you need more information about which one is the best one for your case, you can call us or email us to ask.
Pyrosorb-S Class 0 Acoustic Foam
Pyrosorb-S Class 0 Acoustic foam: Our Pyrosorb-s is a class 0 rated acoustic foam. This is a superior grade of foam in its class. It is manufactured in the UK and distributed worldwide by eFoam.
Closed Cell Polyethylene EFP30 Foam
Closed Cell Polyethylene EFP30 foam: Due to its closed cell formulation, polyethylene is an ideal foam to use for sound deadening applications. Please note, this particular product is not fire retardant. If you require a fire retardant version, please contact us.
We offer a range of acoustic foam, from the flat sheet and convoluted (egg-crate) sheet to bass traps that are typically added to the corner of each room. Our soundproofing tiles can be installed on walls and ceilings with adhesive spray glue, which we also supply for your convenience. If you're not sure about which foam you should be using, get in touch. We are happy to help.
What is acoustic soundproofing foam used for?
Honestly, the list is longer than most people expect. Acoustic foam is one of those products that quietly solves problems in all sorts of places, from a bedroom music setup to a professional recording studio to a busy office where confidentiality matters.
Here are some of the most common uses our customers come to us for:
- Recording studios & home studios: Reducing echo and flutter so vocals and instruments sound clean on playback
- Home theatres & listening rooms: Getting the most out of your audio setup without sound bouncing off walls
- Podcasting & voiceover booths: A surprisingly small amount of foam makes a huge difference to recorded voice quality
- Offices & meeting rooms: Keeping conversations private and reducing distracting noise between spaces
- Drumming & practice rooms: Protecting your neighbours (and your relationships with them)
- Cars & vans: Deadening road noise and improving in-car audio
- Industrial & commercial spaces: Controlling noise in workshops, factories and open-plan environments
- Churches & performance venues: Improving speech clarity and reducing unwanted reverberation
If your use case isn't on that list, get in touch, chances are we've supplied foam for something similar before.
How does acoustic soundproofing foam work?
Sound is essentially energy travelling through the air in waves. When those waves hit a hard surface, a wall, a ceiling, a glass window, they bounce straight back. That's what creates echo, flutter and the muddy, reverberant sound that makes recordings sound amateurish and rooms feel noisy.
Acoustic foam works by absorbing those sound waves rather than reflecting them. The open-cell structure of the foam traps the sound energy and converts it into a tiny amount of heat, so the wave doesn't bounce back and cause problems. The result is a cleaner, more controlled acoustic environment.
Different frequencies need different solutions though. High frequencies such as the treble, the brightness in a voice or guitar, are relatively easy to control with standard acoustic panels. Low frequencies such as bass, kick drum, room rumble, have much longer wave lengths and need something more substantial. That's where bass traps come in. They're specifically designed to sit in room corners where low-frequency energy naturally builds up.
Getting the right combination of panels and bass traps for your space makes a bigger difference than most people expect, and our team are always happy to advise if you're not sure where to start.
I am not sure which soundproofing acoustic foam is the best for me?
That's completely normal, there are a lot of options and the differences aren't always obvious from a product listing. Here's a quick way to think about it:
If you're treating a room for better sound quality, a home studio, podcast booth or listening room, standard acoustic foam tiles or sheets are usually the right starting point. Add bass traps in the corners and you'll notice a significant improvement.
If you need fire-rated foam for a commercial space, a venue or anywhere with building regulations to consider, our Pyrosorb-S Class 0 is the one to look at. It's the highest fire safety rating available for acoustic foam.
If you're not sure at all, the best thing to do is order a sample. It costs very little, arrives quickly, and lets you feel the density and texture before you commit to a full order. Most people find it makes the decision much easier.
Or just give us a call on 0800 0439990 (Monday to Friday, 8am–5pm). Our team have been doing this for over 20 years and can usually point you in the right direction in a few minutes.
Can I order Acoustic foam in the size I want?
Absolutely, and it's easier than you might think. You don't even need to call us. Just head to our acoustic foam cut to size tool, enter your dimensions, and you'll get an instant price online. No waiting, no back and forth.
If your requirements are more complex, unusual shapes, large volumes, or specialist applications, our team are always happy to help.
