What is an acoustic box, and how does it work?
Definition and how it works
An acoustic box is a self-contained, soundproof pod designed to create a private space within an open environment. These prefabricated structures combine sound insulation, ventilation, and lighting systems to deliver an ideal workspace.
The principle relies on multi-layer sound insulation that blocks noise transmission in both directions. An acoustic box reduces ambient noise by 28.7 to 31.1 dB, turning a 65 dB open-plan office into a quiet 35-40 dB space, similar to a library.
Built-in ventilation renews the air every 30 seconds, while automatic LED lighting adjusts to whether the pod is in use. This design meets ISO 23351-1:2020 (Class A for the Solo and Desk, Class B for the Duo and Quattro), the market benchmark since 2020 for professional acoustic pods.
Technology and materials
Modern acoustic pods use multi-layer panels that combine absorption and insulation. The walls include materials such as Métisse® (recycled textiles) and recycled glass, to maximise acoustic performance while respecting the environment.
Laminated glass keeps the pod visually open while maintaining sound insulation. PEFC certification guarantees wood sourced from sustainably managed forests. These eco-responsible materials fit with a CSR approach that matches what modern companies expect.
All the technical components, quiet ventilation, LED lighting, power sockets, USB-A and USB-C, fit seamlessly into the structure to create a complete, self-contained workspace.
The different types of acoustic box for your needs
1-person acoustic box (phone booth)
The individual phone box suits phone calls and short video meetings. With a footprint of 1 m², it fits easily into any open-plan office without disrupting foot traffic.
The Island Solo offers -28.3 dB of sound reduction, with installation in under 1 hour. This acoustic pod includes a power socket, an Ethernet port, and LED lighting with presence detection. Automatic 400 m³/h ventilation ensures optimal comfort.
Priced at €3,990 excluding VAT, this pod can be financed through leasing from €68 a month. Options include a screen (+€790) and a stool (+€240).
2 to 4-person acoustic box (meetings)
For confidential meetings, brainstorming, and HR interviews, multi-person pods give you the space collaborative discussions need. The Island Quattro comfortably seats 4 people in a 2.5 m² footprint, with 800 m³/h ventilation.
This office acoustic pod offers -29.8 dB of reduction and includes 2 power sockets, 2 USB-A ports, and 1 USB-C port. The 2 comfortable seats are included, along with a shelf finished in Vicenza oak melamine.
As Estela Sánchez from Seedtag puts it: "The pods have improved our workspace by taking pressure off our large meeting rooms, while still leaving room for spontaneous calls." At €9,990 excluding VAT, financing starts from €204 a month.
Modular, scalable solutions
Modular solutions adapt as your needs change, thanks to adjustable feet and a design built for moving. This flexibility suits growing companies and frequent reorganisations.
The full range also includes the Island Desk (1 person, seated, €4,790 excluding VAT) and the Island Duo (2 people, €7,990 excluding VAT). Every model keeps the same standards of acoustic quality and technical equipment.
Real benefits of an acoustic box in the workplace
Better productivity and concentration
The sound insulation an acoustic box provides significantly reduces stress and improves concentration. Constant interruptions in open-plan offices drop, giving people a calm environment to recharge in.
This improved workspace translates into a measurable rise in productivity and less auditory fatigue, a factor often underestimated in open-plan offices.
Better use of space, more flexibility
Acoustic pods make better use of space by creating functional zones with no permanent partitioning. They free up traditional meeting rooms for important meetings, while still providing space for informal conversations.
This approach fits flex office needs perfectly, where spaces need to adapt quickly to different ways of working. Because the pods can be moved, you can reconfigure your layout as teams and projects evolve.
The small footprint (1 to 2.5 m²) maximises the number of workstations while still providing the privacy zones you need. This spatial efficiency improves the return on your real estate investment.
Privacy and wellbeing at work
Privacy is a major issue in open-plan offices, where professional conversations can be overheard by everyone. Acoustic boxes create the privacy bubbles you need for client calls, interviews, or strategic discussions.
Feedback from our many customers confirms the positive impact on team wellbeing. Being able to step away at any time reduces stress and improves quality of life at work.
This improved wellbeing also shows up as fewer stress-related sick days and better talent retention, since people are particularly sensitive to the quality of their work environment.
How to choose the right acoustic box for your office
Key technical criteria
Acoustic performance is the key criterion, measured in decibels of reduction. Look for certification to ISO 23351-1:2020 Category B to ensure optimal insulation. Quiet ventilation should deliver 250-500 m³/h, depending on capacity.
Ergonomics covers automatic LED lighting, built-in power and Ethernet sockets, and a workspace that fits its purpose. Connectivity should meet today's technology needs with USB-A and USB-C ports for mobile devices.
Materials should combine performance and durability, backed by environmental certifications (PEFC, recycled materials). Easy maintenance and resistance to heavy use protect the investment over time.
Assessing your needs and sizing
Assessing your needs starts with looking at usage: how often people call, how long meetings usually run, and how many people need a pod at once. A tailored assessment helps determine the right number of pods for your open-plan layout.
Identify your priority activities: short calls (phone booth), long meetings (multi-person pods), focused work (seated version). This assessment determines the best mix between models.
Our hands-on experience lets us support you through this thinking, to meet a range of needs while getting the most from your investment.
Budget and financing options
The range runs from €3,990 to €9,990 excluding VAT, depending on capacity and equipment. Custom options add €300 to €900: built-in screens, video conferencing equipment.
Leasing makes the investment easier, with monthly payments from €79 a month. This option preserves cash flow and spreads the cost over the accounting depreciation period.
Financing options also include long-term rental with maintenance included, a good fit for companies that prefer operating costs over capital assets.
Installation and fitting into your workspace
Installation with no construction work, and technical constraints
Installation with no construction work is a major advantage of modern acoustic boxes. The plug-and-play system only needs a standard power connection, with no changes to the building structure and no special permits.
Full installation takes under 1 hour, depending on the model. This speed keeps disruption to a minimum and gets the pod up and running straight away.
Our teams handle delivery, assembly, and set-up anywhere in Europe within 20 days. Included user training helps your teams get the most from the equipment.
Positioning the pod
The best spot avoids heavy foot traffic while staying easy to reach. Allow enough room for the door to open and for people to move around the pod.

Scalability and reconfiguration
This scalability suits growing companies. Adjustable feet and a modular design mean the pod can be moved by 2-3 people, depending on the model, in just a few hours.
This flexibility adapts to layout changes with no loss on your investment, unlike fixed partitions. Modularity makes it easier to adapt as teams grow and ways of working evolve.
Investment and return on investment for an acoustic box
Acquisition and running costs
Acquisition costs range from €3,990 to €9,990 excluding VAT depending on the range, plus custom options (€300 to €900) and installation (€500 to €1,400). This transparent pricing makes it easier to budget for your project.
Running costs stay minimal: power consumption similar to a computer, with optional annual preventive maintenance. With no complex wear parts, upkeep is limited to periodic cleaning.
Leasing spreads the investment over 48 months with predictable monthly payments. This approach improves cash flow and lets you treat the cost as an operating expense rather than a capital investment.
Calculating ROI and economic benefits
The return on investment rests on several factors: productivity gains, savings on office space, and lower turnover. Payback generally happens over 2-3 years, through better use of space and improved performance.
Space savings come from freeing up traditional meeting rooms, which can then be put to other productive use. Lower noise levels reduce stress and absenteeism, generating meaningful indirect savings.
A more attractive workplace makes recruitment and talent retention easier, cutting the cost of staff turnover. This economic picture, based on feedback from our customers, shows the investment pays off.
