What is a soundproof box?
A soundproof box, also known as an acoustic pod or phone box, is an enclosed space designed to give optimal sound insulation in the workplace. These modular structures use specialised acoustic materials to significantly cut noise, both inside and outside the pod.
Modern acoustic pods use multi-layer panels combining acoustic foam, rock wool, and absorbent materials. This design achieves sound insulation of 25 to 35 dB of reduction, to ISO 23351-1.
These private spaces fit into open-plan offices, coworking spaces, call centres, and shared offices. They answer the growing need for concentration, privacy, and wellbeing at work.
The four main uses of an acoustic pod include:
- Confidential phone calls
- Tasks that need focus
- Small-group meetings
- Remote training sessions
- Team brainstorming
Companies that install acoustic solutions generally see an improvement in team productivity.
The different types of acoustic box
Individual pods (1 person)
The 1-person pods, with a footprint of around 1 m², are designed for phone calls and individual focus. Fitted with quiet ventilation, automatic LED lighting, and power sockets, they give you the ideal environment for tasks that need concentration.
These models include advanced technology: screens, video conferencing systems, USB-A and USB-C ports. A particularly good fit for remote work and virtual meetings, these connected pods turn any open-plan office into a private office.
Collaborative pods (2 to 4 people)
The 2-person pods (around 2 m²) suit one-to-one meetings, HR interviews, and brainstorming sessions. They usually come with two comfortable seats and a shared work surface with stronger connectivity.
The 4-person models (around 2.5 m²) are designed for team meetings, client presentations, and training. Their stronger sound insulation keeps conversations private, even during lively discussions.
At Siemens, installing acoustic pods brought a satisfaction score of 4.6/5 from employees, with growing demand for additional spaces. B Corp and Origine France Garantie certification reflects the quality and environmental commitment of leading manufacturers.
Key technical specifications
Sound insulation performance
Acoustic performance is measured in decibels (dB) of sound reduction. Class B pods offer 25 to 30 dB of insulation, enough for most office uses. This certification guarantees an insulation quality verified by independent bodies to ISO 23351-1.
The panels use PEFC materials (certified wood), combined with high-density acoustic foam and absorbent fabrics. This combination absorbs voice frequencies (500-2000 Hz) effectively, creating an environment suited to concentration and privacy.
Built-in features
A quiet ventilation system (under 35 dB) renews the air users need for comfort. Automatic LED lighting switches on with presence detection, cutting energy use while creating a pleasant working atmosphere.
Power sockets, Ethernet, and USB ports let you connect laptops, screens, and video conferencing equipment. Some models include touchscreens for booking and managing spaces, making it easier to organise teamwork.
Work With Island pods reach 31.1 dB of sound reduction, with automatic ventilation and adaptive lighting. These acoustic tests follow AFNOR standards, carried out by COFRAC-certified laboratories.
Standard equipment includes:
- Quiet automatic ventilation
- LED lighting with presence detection
- Power sockets
- USB-A and USB-C ports
- Ergonomic work shelf
- Adjustable feet for levelling
Benefits of acoustic pods in the workplace
Installing soundproof boxes brings a significant improvement in productivity. Fewer noise interruptions support concentration and the quality of work, especially for complex tasks that need sustained attention.
Being able to step away from ambient noise reduces stress and auditory fatigue. A large majority of users report better comfort at work after acoustic pods are installed, changing their day-to-day office experience.
Sensitive conversations (HR, sales, legal) benefit from insulation that protects confidentiality. This acoustic security is especially valued in banking and consulting, where discretion matters most.
Unlike traditional meeting rooms, acoustic pods install directly in the open-plan office, making the most of available space. Their modularity allows reconfiguration as the company's needs evolve.
"What our employees told us: noise is tiring and wears you down. They need moments to recharge, to pause and step away. The pod lets you fully step away, into a completely quiet atmosphere." - WiiSmile customer testimonial
Feedback from more than 4,000 equipped customers, including Siemens, RATP Real Estate, and Qonto, confirms these measurable benefits on the ground.
Choosing a soundproof box: what to check
Assessing your needs
Defining the main use determines the best choice: phone calls (1-person pod), confidential meetings (2-person), or collaborative sessions (4-person). This assessment directly shapes the size and equipment you need to get the most out of the pod.
For heavy use (over 6 hours a day), favour models with stronger ventilation and durable materials. Occasional use allows for more affordable versions, while keeping the essential acoustic performance.
Technical constraints
Measuring the exact location matters: ceiling height, floor space, and access for installation in particular. Allow 50 cm of clearance around the pod for ventilation, to get the best performance and comfort. All the technical details of our pods are available in our product guide.
Check that a power socket is available nearby, to make installation easier.
Budget and financing options
Prices range from €3,990 (1-person pod) to €9,990 (equipped 4-person model). For tighter budgets, refurbished pods are available through the "Work With Me Again" programme, with a manufacturer warranty.
Sales and customer service teams particularly value these quiet spaces dedicated to their calls. French manufacturing guarantees quality and traceable materials.
Installation and maintenance of acoustic pods
Installing an acoustic pod usually takes a few hours, depending on the model. The prefabricated parts go together with no major construction work, allowing immediate use with minimal disruption to your team.
Checking the floor is level (5mm tolerance), that there's access for moving the parts in, and that power is nearby makes the process easier. Adjustable feet compensate for minor unevenness, ensuring a stable, lasting installation.
Maintenance is limited to cleaning surfaces (fabric, glass). The materials used resist wear and keep their acoustic properties over time, keeping maintenance costs low.
Manufacturers typically offer 2 to 5 years of warranty on structural parts and 1 year on electronic equipment. A preventive maintenance service can be added to extend the pod's life and maintain performance.
"Work With Island's great strength is being able to respond, from sales all the way to logistics, to install the pods smoothly and simply." - Maxime Cohendet, Co-founder at Wefy Group
