FAQs - frequently asked questions

Yes. In 2024 and 2025, we developed an extra-flat acoustic floor in collaboration with our research partners, which we can install upon request. Compared to our conventional acoustic floor, it saves 7.5 cm in entry height, yet offers the same sound-absorbing properties and is even 2 to 3 decibels better in terms of impact sound insulation (more information here).

While it is possible to omit the acoustic floor and place the cabin directly on the room floor to access it without a threshold, this is not an ideal solution. The very high sound insulation of our cabins would be reduced. – Therefore, we offer various access aids (ramps) that allow for easy entry into the cabin.

We also offer extra-wide soundproof doors and leveling of the floor and door threshold for easy exit from the cabin. Our planning team can provide further details.

Our most important international partners are the Fraunhofer Institute – Europe's most renowned and largest institution for applied research with more than 32,000 employees – and the international acoustic design firm WSDG (headquartered in New York with its European headquarters in Basel). We have been collaborating with both for many years.

Furthermore, synergies and know-how transfer have been achieved since STUDIOBOX became part of the Hutter Acustix group of Austrian carpentry firms – an internationally renowned expert in room acoustics with many spectacular projects. One of these, the high-end recording studio of Mixed with the Masters in Paris, received the NAMM TEC Award in California in 2024 for the most beautiful recording studio in the world. Learn more.

All of this, in-house research and further development in material properties and equipment, ensures that STUDIOBOX soundproof booths meet the highest requirements of all users – be it in terms of quality, functionality, reliability, progressiveness, sustainability or climate protection.

The STUDIOBOX warranty covers functional defects and manufacturing or material defects and is valid for 24 months from the date of purchase (invoice date) for all load-bearing parts of the enclosure construction, acoustic panels, seals, and door fittings. The provisions of the German Civil Code (BGB) generally apply.

For purchased components (e.g. our AEROPAC fans), the respective dealer or supplier warranties and statutory warranty claims apply.

Warranty claims apply to the original owner (first occupant) of a STUDIOBOX and are not transferable.

The warranty is void in cases of gross misuse, vandalism, accidental damage, lack of proper care/maintenance, or unauthorized modification of the booth by the owner. There is also no warranty for damage resulting from improper (faulty) assembly that does not follow the STUDIOBOX assembly instructions.

The warranty is also void if a STUDIOBOX is used outdoors, as our booths are designed exclusively for indoor use. This also applies to use in rooms with a consistently high relative humidity above 60 to 65 percent (e.g., damp basements, bathrooms, etc.), as the booths contain a high proportion of wood, and the material can swell, warp, and/or become affected by mold and mildew.

Our soundproof booths have been available since 1990. Even today, we still receive inquiries from customers who own models from the very first generation and need assistance relocating their booths. So, our soundproof booths last that long (and probably much longer) – provided they are treated with care.

Should one of our cabins ever reach the end of its lifespan, ALL components are 100% recyclable. That's what we mean by sustainability in practice.

Mass (along with high vertical integration, material selection, vibration behavior, etc.) is one of the most important criteria for optimal sound insulation. That's why high-quality soundproof booths are also quite heavy. How heavy depends on the size of the booth.

Generally speaking, the larger the booth, the lower the weight per square meter. Furthermore, loads (with solid construction) are distributed across the entire ceiling area of ​​a room, and nearby walls usually also support a portion of the load. Waterbeds, aquariums, or grand pianos often exert a higher load per square meter.

For legal reasons, however, we must point out that without more detailed information about the site or consideration of the construction details/quality, we cannot make any binding statements or recommendations. In critical cases (especially in very old buildings with timber frame construction), a structural engineer should be consulted for safety reasons.

HOWEVER: Since STUDIOBOX was introduced (1990), we are not aware of a single case where the ceiling load check did not result in an OK.

The complete package. Whether it's the quality of the sound insulation and workmanship, the expandable modular system, individual design options, tool-free and quick assembly, Europe-wide delivery and assembly service, and much more. And all this at a price that is by no means at the top end of the scale. Quite the opposite. Why is that? Well, that's our little secret.

We strongly advise against this. The booths have a high wood content and are designed exclusively for indoor use. Rooms with consistently very high humidity (e.g., damp basements, bathrooms) are also unsuitable, so we cannot accept any warranty or guarantee for damage resulting from setup in such unsuitable locations.

That depends on a number of factors – such as model, size, features, and much more. Please send us a price inquiry for your desired booth, and we can calculate all costs for you without obligation.

No. STUDIOBOX is not an industrial product distributed through large warehouses and intermediaries. Rather, our booths are entirely handcrafted – from the first to the last step. We build our soundproof booths exclusively to customer specifications and deliver directly from the factory. This has many advantages – including price.

The classic STUDIOBOX line (since 1990) includes the STANDARD, PROFESSIONAL, PREMIUM, and MEASURING BOX models. The biological ROSI line offers the ROSI RELAX (with the ROSI RECOVERY application variation) and ROSI STUDIO models. Each model is available in a wide variety of sizes and configurations.

There are two key aspects:

1. Interior acoustics: You can find all the information under “FAQ – Interior Acoustics”.
2. The choice of materials: While the booths in the ROSI organic line are made entirely of local wood and wood-based materials (excluding windows, fittings, and seals), the classic STUDIOBOX line (which also has a high wood content) uses other materials (wood composites). These are all certified and non-toxic (e.g., by complying with the DIN EN 14041:2004/AC:2006 standard, etc.). We have always categorically avoided the use of any plastics that are harmful to the environment and health (e.g., PVC, polystyrene, polyurethane, etc.).

The possibilities are almost endless. Here is an excerpt of the most important application areas:

• - Research (e.g., neuroscience, psycholinguistics, audio research, process qualification & validation)
• - Medicine (e.g., audiometry, e-health, telemedicine, clinical trials)
• - Industry (product development, component testing, sound development, measurement technology)
• - Broadcast & Recording (e.g., radio & television studios, vocal booths, recording studios for musicians, video direction, mastering, app development, multimedia & e-learning)
• - Making Music (practicing with all instrument groups, home recording, music lessons)
• - Voice Recordings (e.g., podcasts, audiobooks, interviews)
• - Interviews & Office Work
• - Gaming
• - Sleep & Recovery (ME/CFS, Long Covid, Sleep Disorder, Hyperacusis, Shift Work, Burnout)

High-quality soundproof cabins effectively shield sufferers from sensory stimuli such as noise and light. This leads to a reduction in stress levels and improved sleep depth, and can help alleviate symptoms of the illness and promote or accelerate the recovery process. Details on the requirements for and added value of sleep cabins can be found in our blog post.

The path to the right model begins with answering these questions: What do I want to do in the booth? Work? Research? Measure? Sleep? Record? Or play music? If so, which instrument? Then: What is most important to me? Primarily the best possible sound insulation? Or also optimized room acoustics, even up to recording studio quality?

Once these basics are clear, this table on our website allows you to compare all the booth features at a glance. If you are still unsure, our team is always happy to help – based on decades of experience (since 1990) and feedback from thousands of customers in various industries worldwide.

Important: The quality of the sound insulation alone is not the deciding factor when choosing the right model, because the sound level reduction – with minimal, practically imperceptible variations – is the same for all STUDIOBOX models (whether classic or biological). Up to -53 decibels. Learn more.

We use two devices that together form a fan set:

a) Natural ventilation in the form of a passive unit

b) Electronically controlled air supply in the form of an active unit

The natural ventilation (passive unit) is standard in every booth and works on the principle of pressure differential. The electronically controlled air supply (active unit, optional) operates with a multi-stage control system and, at maximum operation, delivers up to 180 m³/h of fresh air from the surrounding space into the booth.

Automatic activation and deactivation of the active ventilation when entering or leaving the booth, using sensors, is also available as an option.

For large booths (and for intensive use with high oxygen consumption), we recommend installing a second or even more fan sets.

No. There is absolutely no disturbance. Measurements by our acoustics department have shown that at a medium setting (air circulation between 30 and 60 m³/h), the unit runs so quietly that only your own breathing can be heard in the cabin. – For demanding applications in soundproof cabins, we are unaware of a better device on the global market.

Yes, that's always possible. Our planning department can provide further details.

The active (electronic) supply air unit is mounted on the wall inside the cabin, just above the floor. The passive exhaust air unit is mounted just below the ceiling and, if possible, diagonally opposite (for optimal air circulation). Our team will gladly provide recommendations for the best positioning.

If the ventilation units are undesirable inside the cabin or if there is no suitable space for them due to user reasons, external mounting on the wall and/or ceiling is also possible. Our planning team can provide further details.

No, absolutely not. Even with the passive unit, which is installed as standard in every STUDIOBOX, sufficient oxygen enters the cabin. Even for those who sleep in extremely late, because: Even after 48 hours – without opening the soundproof door even once – the oxygen saturation is still high enough.

No, there is no loss whatsoever. All inlets and outlets are appropriately insulated.

Yes, with an optional air conditioning system. Our air conditioning uses a split system, which operates on a two-component principle. The compressor is mounted externally, while the actual cooling and dehumidifying fan is located inside. Both units are connected via soundproofed pipes that run through the booth wall. This ensures that there are no disruptive operating noises or vibrations inside the booth.

Both, depending on our customers' wishes. The following answers most frequently asked questions.

We don't know exactly ourselves 😊. There are practically unlimited possibilities. While we do have a standardized internal dimension of 60 cm per element, intermediate sizes are always possible – in 10 cm increments for both length and width. The largest cabin we've built so far is nine meters long.

The only limitation: We deliberately limit the cabin width (internal dimension) to 480 cm for structural reasons. Wider cabins are possible, but the construction effort is significantly greater and seems disproportionate to us.

Short answer: many. The standard interior height for all models is 205 cm. Adjustments both upwards and downwards are possible in 5 cm increments for an additional charge. Our team will be happy to provide further information.

Depending on the type of acoustic flooring we install, 27 or 20 cm must be added to the interior height to obtain the total cabin height. This determines the required installation height (room height).

As a guideline: at least an additional 8 centimeters to the cabin height. This amount of vertical space is needed for installation. In special cases, however, we can take additional measures to save space (see also the next question).

Yes, we do. In a research project with the Fraunhofer Institute and WSDG, we developed an extra-flat acoustic floor (see also: Accessibility FAQ) that provides valuable extra centimeters. And we can design the booth so that hardly any space is lost vertically and it reaches almost to the ceiling. Our team can provide more information upon request.

Yes, of course, that's possible. However, depending on the model, size, and age of the soundproof booth, there are a few parameters to consider that may limit subsequent changes to the booth size. Our planning team is familiar with the details for each booth and will gladly assist with the implementation.

Approx. 11 centimeters in a double-shell construction.

As a rule of thumb, we always recommend 30. - This is how many centimeters must be added to the desired internal dimensions (length and width) to determine the external dimensions, taking into account wall thickness and the booth base.

Example: A booth with internal dimensions of 240 x 240 cm will have an overall size of 270 x 270 cm. A few more centimeters are needed for the minimum distance to the wall. The booth and the room wall must not touch, as this can lead to unwanted sound transmission.

If you want a STUDIOBOX to be so large that it fits as close as possible to three walls of a room, or even fills an entire room, our planning team will gladly calculate the maximum possible booth size that is still feasible.

Each booth (except the small MEASURING BOX) includes sound-absorbing wall and ceiling panels, impact sound-insulated floor panels, model-specific interior acoustics, one small window, one soundproof door (without a viewing window), interior carpeting, one passive ventilation unit, one interior power outlet with a triple socket, and one or more wall-mounted LED light strips (depending on booth size). Details here.

Since we handcraft all our booths in our carpentry workshop, the range of options is virtually limitless. It includes everything from studio glass doors and parquet flooring (standard on all ROSI models) to lightproof interior blinds and soundproofed inlets for external utilities (e.g., for ME/CFS), and much more. Further details can be found in this selection on our website or by contacting our planning team.

In principle, any number of units are possible. However, should any acoustic disadvantages arise (e.g., due to opposing glass surfaces and the risk of unwanted sound reflections), our team will automatically provide recommendations.

Yes. Both soundproof doors and windows are available with different visible surface heights (e.g., 73 x 36 or 138 x 36 cm). We also offer large-format studio glass doors in timber frame construction and panoramic studio windows spanning multiple wall elements, as well as special shapes (e.g., portholes). Details available upon request.

Yes, of course. The limitations due to construction reasons are minimal – our team can provide more details.

Yes, that's always possible. All our booths are handcrafted in a specialized carpentry workshop. This allows us to fulfill almost any special request. Important: Customizations of this kind usually result in longer delivery times than usual.Custom sizes and XXL booths: I'd like a hexagonal STUDIOBOX – is that possible? Yes, absolutely. A hexagonal booth is no big deal; it's quite feasible. We also build booths "around corners" (L-shaped), with beveled corners and corner doors, or extra-large booths (XXL). Even booths adapted to sloping ceilings are no problem.

However, please note that in all these cases, the construction may be more complex and therefore more expensive than with standard sizes.

STUDIOBOX booths are used in a wide variety of applications – as music practice rooms and professional recording studios, podcast and audiobook production rooms, radio and TV voice-over booths, control rooms, research labs, industrial testing and certification booths, office retreats, gaming rooms, sleeping booths, and much more. The possibilities are virtually limitless.

Therefore, we ask our customers to provide details about their intended use when we first contact them. Our team will then provide the appropriate recommendation. Anyone who wants to compare all the features of all models at a glance can do so using this table on our website.

The answer is almost always: No.

We also offer an all-inclusive acoustic service and don't expect our customers to delve into the scientific field of room acoustics if they don't want to. We have our own in-house, academically trained acoustic professionals who are happy to take care of it.

That's why we always ask about the intended application. If the customer agrees to our proposal or has already made the optimal choice themselves, they receive an acoustically optimized STUDIOBOX for their specific needs, which they can use immediately after setup and at full quality.

Exception: Only for special applications (e.g. for product certifications in industry, targeted excitation in the low-frequency range below 100 Hz, etc.) do we recommend additional acoustic measures - tailored to the respective application - which we will gladly implement upon request.

Yes, even for such special cases, there are options for completely individual adjustments that we can implement and deliver directly from the factory. Our in-house acoustics team can provide details upon request.

Yes, of course we deliver outside of Europe as well. We have customers all over the world and work with reputable, reliable shipping companies as strong partners, such as Kühne + Nagel, one of the world's largest logistics companies. – After consultation and purchase, we also oversee the delivery process right to the end, so that you receive your booth on time, at the agreed location, and in the agreed quality.

If the customer chooses to assemble it themselves, our shipping partners will deliver the cabin to your doorstep (curbside).

There are two options:

1. Our installer brings the cabin in his van. He has his own packaging system for this
2. The cabin is delivered by freight carrier. In this case, all components are packed on pallets. Delivery by freight carrier truck is used either ...

• … for self-assembly by the customer,
• … for large cabins that our installer assembles for the customer but cannot transport in his own vehicle, or
• … in the case of distant delivery locations, where our installer travels by plane instead of by car (because this saves time AND is cheaper for the customer).

Yes, that's possible. We produce at two locations: one in Germany near Stuttgart, and the other in Austria near Graz. At both locations, the STUDIOBOX is packed on custom-made pallets, prepared for transport, and then lifted into the vehicle (van, truck) using a forklift. Our team can provide the exact dimensions and weight of the pallets upon request.

After a binding order and down payment (see payment terms), the booth goes into production. From then on, it usually takes 6 to 8 weeks for us to deliver the STUDIOBOX.

For custom orders and large orders, please allow an extra week or two. Delivery may also take longer if production at both factories is running at full capacity for an extended period. Details available upon request.

Yes, that's possible. Depending on the size of the soundproof booth, two to four strong helpers are needed to assist with carrying and assembling the elements.

No, usually not. With a little skill and muscle power, smaller cabins in particular can easily be installed yourself. We provide detailed assembly instructions and are available online for assistance if needed.

However, for large cabins and/or those with special features (e.g., panoramic windows spanning multiple panels, internal locks, etc.), as well as for special projects (see our BLOG), we recommend our comprehensive, worry-free assembly service, which we offer throughout Europe.

For most booths, between 1 and 4 hours. Only larger booths might take an hour or two longer. This video on our website shows an example of two of our installers assembling a 180 x 180 cm soundproof booth, model PREMIUM. They even managed it in 37 minutes – without any undue haste 😊.

None at all, with one exception. For mounting the door, we recommend a cordless screwdriver (although a regular screwdriver will also work) to screw in four screws to secure the door to the door frame. Everything else can be done by hand.

Yes, we do. More than 98 percent of our customers take advantage of our worry-free service.

The price for delivery and assembly depends on many factors – from the size of the booth and the distance from the factory to the installation site, to the site conditions (access for the truck, elevator, etc.). Our team always calculates the most cost-effective rate for each customer individually upon request.

Throughout Europe. And for larger orders (or complex special projects), worldwide. Our team will be happy to answer any questions you may have.

We deliver the booth. Our technician also arrives, and with a few strong helpers (either provided by the customer or, upon request, organized and booked by us) to assist with carrying the components, the STUDIOBOX installer oversees the assembly.

Immediately after assembly, the booth is ready for full use.

The good news: not at all. No drilling. No hammering. No sawing. No other noise. All elements of the soundproof booth are prefabricated down to the last detail in our factory and are simply assembled on-site, securely connected with metal fasteners. Even for highly sensitive people or those with medically related noise intolerance, the assembly is easily tolerated.

In principle, there is no limit – provided the booth is handled with care. One of the key quality features (besides the sophisticated modular system) is the high level of craftsmanship thanks to the combination of handwork and CNC technology. This ensures consistent quality in terms of sound insulation and room acoustics – for decades to come.

In principle, yes. The modular system allows for this. However, depending on the size, model, fan positions, etc., there are a few things to consider. Therefore, we recommend consulting our planning team beforehand. We will create possible new configurations of the booth using the existing elements free of charge.

Absolutely. Anytime. We're happy to help if you wish. We have our own relocation service that operates throughout Europe. Simply submit an inquiry via the contact form – and we'll take care of everything. Promptly. On time. Reliably.
