Effectively reduces reverberation time
Significantly improves speech intelligibility
Enables individual wall design
Effective sound absorption and creative room design
HOFA Hexagons are made of HOFA PureAkust and achieve sound absorption class A. They noticeably reduce unwanted reverb in your room. Since the honeycombs can be arranged in any pattern, your acoustic solution also becomes a visual highlight on the wall.
Acoustic Effectiveness of the HOFA Hexagon
With a material thickness of 40 mm, HOFA Hexagons offer outstanding absorption performance with a low wall profile.
In typical applications, the Hexagons meet sound absorber class A (according to EN ISO 11654) and have significantly higher absorption than standard brand products (up to 55% more compared to melamine resin foam and up to 70% more compared to convoluted foam of the same thickness).
Practical sound absorption coefficient rated according to ISO 11654

Frequently Asked Questions about HOFA Hexagons
What are HOFA Hexagons and what are they used for?
HOFA Hexagons are hexagonal sound absorbers made from our sustainable PureAkust material. They achieve the highest sound absorption class A and reduce reverb, flutter echoes, and disturbing reflections. This significantly improves room sound and speech intelligibility. Thanks to their honeycomb shape, they can be combined into custom patterns on walls and ceilings. They are available in white, gray, and black, allowing acoustics and wall design to go hand in hand.
They are used wherever better room acoustics are required: in offices, living and Hi-Fi rooms, recording studios, podcast and streaming setups, in gastronomy, or in educational institutions.
In which frequency range do HOFA Hexagons work?
HOFA Hexagons work from approx. 300 Hz and absorb very effectively across the entire mid and high-frequency range – exactly where the frequencies of speech and most musical instruments lie. In typical applications, they achieve the highest sound absorption class A according to EN ISO 11654.
What does sound absorption class A mean?
The sound absorption class is a standardized classification according to EN ISO 11654 that indicates how much sound a material absorbs. The scale ranges from Class A (highest absorption) to Class E (low absorption).
Class A means that almost all incident sound is absorbed – a material in this class is among the most effective sound absorbers available. HOFA Hexagons achieve this value in typical applications, ensuring a particularly effective reduction of reverb and disturbing reflections.
How do I improve speech intelligibility in my room with HOFA Hexagons?
Poor speech intelligibility and an overall unpleasant noise level are usually caused by excessive reverb and uncontrolled reflections. This is exactly where HOFA Hexagons come in: they absorb incident sound across a wide frequency range and ensure acoustic calming of the room. This gives you a clearer, more intelligible sound – whether in conversation, video conferences, or podcasts.
For optimal results, we recommend mounting the Hexagons as close as possible to the sound source (e.g., next to the desk, meeting table, or microphone position).
How do I improve the acoustics in my studio or Hi-Fi room with HOFA Hexagons?
In recording studios and Hi-Fi rooms, a controlled reverberation time is crucial for a precise, transparent sound image. If it is too long, details blur, the stereo image becomes fuzzy, and mixing decisions or listening enjoyment suffer. HOFA Hexagons effectively reduce reverb across the entire mid and high-frequency range and additionally absorb disturbing first reflections from the wall or ceiling before they reach the listening position.
For optimal results, mount the Hexagons at the first reflection points of your room (we are happy to advise you on this).
How are HOFA Hexagons mounted?
There are two options for mounting:
With assembly adhesive: We provide you with a sufficient amount of assembly adhesive. You apply this to the Hexagon module first and then attach the module to the wall. Before the adhesive hardens, the module position can still be slightly corrected. This mounting method also allows for flush mounting of the modules.
With serrated hooks: Here, you first attach the bracket to the Hexagon module with two screws before mounting it to the wall on another screw. The serrated hook allows for easy adjustment of the alignment.
Both variants can be implemented quickly and without special tools; assembly instructions are included.
How many HOFA Hexagons do I need for my room?
A Hexagon set consists of 9 modules. How many sets you need depends on several factors: room size, ceiling height, existing furniture, and above all, how the room is used. A recording studio or Hi-Fi room usually requires more absorbent surface area than an office or meeting room, as a shorter reverberation time is required here.
As a rough guide: for smaller rooms, 1–2 sets are usually enough to achieve a significant improvement. For larger or acoustically more demanding rooms, more are needed accordingly.
We would be happy to advise you on how many Hexagons your room needs and recommend the optimal placement for the best possible result. Simply contact us.
Can I combine HOFA Hexagons with other acoustic modules?
Yes, very well!
Within the HOFA Style-Line, the Hexagons are perfectly matched to HOFA ceiling sails, wall sails, partition walls, and desk partitions – they are made of the same material and match perfectly visually.
For more demanding acoustic requirements, such as in recording studios or Hi-Fi rooms, they can also be excellently combined with modules from the HOFA Studio-Line – for example, with bass traps for the low-frequency range or diffusers for a more natural spatiality.
Hexagons are also an ideal addition in combination with HOFA acoustic curtains: while the curtains absorb reflections on window surfaces and reduce noise, the Hexagons handle sound absorption on the walls – creating all-round balanced room acoustics.
What material are HOFA Hexagons made of?
HOFA Hexagons are made of HOFA PureAkust, a highly effective absorber material made largely from recycled PET bottles. One Hexagon set, for example, contains around 19 recycled PET bottles.
PureAkust is not only acoustically highly effective but also has many other positive properties:
- pollutant-tested and allergy-friendly
- free of formaldehyde and binders from glass or stone wool
- odorless and bacteriostatic
- certified according to Oeko-Tex Standard 100 (highest product class)
- flame-retardant (fire protection class B1 according to DIN 4102-1 and EN 13501-1)
Thus, HOFA Hexagons combine high acoustic effectiveness with sustainability and health safety – made in Germany.
What should I look for when buying Hexagons?
When buying Hexagon modules, you should pay attention to these points in particular:
Material optimized for acoustics: Many Hexagon modules consist of simple insulation materials that were not originally developed for room acoustics. HOFA Hexagons, on the other hand, are made of a material specifically optimized for acoustic applications, which achieves significantly higher absorption values (up to 55% more than melamine resin foam and up to 70% more than convoluted foam of the same thickness). It is also durable, pollutant-tested, allergy-friendly, and Oeko-Tex Standard 100 certified.
Reliable measured values: In addition to material thickness, the density of the material also plays a major role in the absorption behavior of acoustic modules. Therefore, make sure that the acoustic effectiveness is proven by independent measurements – ideally sound absorber class A according to EN ISO 11654, supplemented by absorption diagrams from the reverberation room method according to ISO 354.
Made in Germany: There are many cheap imports on the market where quality, freedom from pollutants, and actual acoustic effect are often not verifiable. HOFA Hexagons are manufactured entirely in Germany – with controlled materials, high processing quality, and short transport routes.
Advice and Service: Also make sure that the provider offers individual acoustic advice and personal customer service – so you always have a reliable contact person and invest in effective and sustainable solutions.
