Open office acoustic planning
Privatsphärenkabinen vs. Akustikpaneele für Großraumbüros
Compare a privacy booth with acoustic panels for speech privacy, focus, and private calls. Learn when each works, when a hybrid plan is better, and how to estimate booth quantity before requesting a quote.
Schnelle Antwort
Die privacy booth vs acoustic panels decision depends on the problem you need to solve. Acoustic panels reduce reflections and reverberation across a room. A privacy booth creates an enclosed one-person space for private calls, video meetings, and short confidential conversations.
Panels are usually the better first step for an echoey office. A booth is the better fit when employees have nowhere reliable to take calls without being overheard or disturbing nearby teams. Many open offices need both.
Booth quantity should not be based on total headcount alone. Start with normal busy-day attendance, identify peak simultaneous private-call demand, and adjust by department. Sales, customer support, recruiting, and other call-heavy teams usually require more booth access than departments with fewer live conversations.
Privacy Booths and Acoustic Panels Solve Different Problems
Office noise complaints often get grouped together, even when they have different causes. One employee may be reacting to an echoey room. Another may be distracted because nearby speech is easy to understand. A manager may simply have nowhere to hold a confidential call.
Those problems do not have one universal acoustic solution.
Acoustic panels absorb some of the sound energy that would otherwise reflect from hard walls, ceilings, glass, or other surfaces. They can reduce reverberation and make a room feel less harsh. They do not form a sealed boundary around the speaker.
A privacy booth solves a more localized problem. It gives one person a defined, enclosed place to speak or join a video meeting. This matters because intelligible speech is a major source of disturbance in open offices. A study of 21 open-plan workplaces found that background speech was central to perceived noise disturbance, with the distance over which speech remained understandable playing an important role in the result (PubMed).
Privacy Booth vs Acoustic Panels: Decision Matrix
The matrix below is not a product scorecard. It is a problem-definition tool. A well-designed panel installation can be excellent at reverberation control without providing call privacy. A well-specified booth can provide a useful private destination without fixing the acoustic character of the entire floor.
| Entscheidungsfaktor | Privacy Booth | Acoustic Panels |
|---|---|---|
| Primary problem solved | Lack of enclosed one-person privacy | Excess reflection and reverberation |
| Private Anrufe | Strong fit when the booth is specified and placed correctly | Limited; panels do not enclose the speaker |
| General room comfort | Helps the booth user and nearby area, not the whole floor | Can improve a broader room or zone |
| Ablenkung durch Sprache | Creates a dedicated place for the speaker | May reduce reflected sound but not necessarily speech intelligibility |
| Auswirkungen der Installation | Modular placement, assembly, power, and access planning | Wall, ceiling, partition, or suspended installation |
| Flexibilität | Can be relocated when the route and product design allow | Usually remains attached to the treated area |
| Capacity planning | One person per booth; quantity must follow peak demand | Coverage follows room size, surfaces, and acoustic design |
| Bester Anwendungsfall | Calls, video meetings, HR check-ins, and short confidential work | Echo control, meeting-room clarity, and hard-surface acoustic comfort |
When Acoustic Panels Are Usually Enough
Acoustic panels are usually the better starting point when the main complaint is about how a room sounds rather than where private conversations happen.
- Speech and video calls sound sharp or echoey inside a meeting room.
- Hard ceilings, glass walls, and bare floors create long reflections.
- Employees describe the space as tiring even when call volume is moderate.
- Collaboration areas spread sound because few absorptive surfaces are present.
- Private rooms already exist, but their internal acoustic comfort is poor.
Where Panels Stop Helping
Correctly selected and placed Büro-Akustikplatten can improve the shared environment. Placement and mounting still matter. Decorative coverage alone is not an acoustic plan, and a product should not be described as a soundproof panel merely because it absorbs sound.
Panels are not enough when the real complaint is, “I can hear every word of that call.” Absorption may lower reflected energy, but it does not create the physical separation required for dependable one-person call space.
When a Privacy Booth Is the Better Fit
A booth becomes the stronger option when the office lacks a reliable destination for recurring one-person conversations.
Typical Signs
- Sales or customer-support calls spill into nearby work areas.
- Employees use corridors, stairwells, or building lobbies for calls.
- HR, finance, recruiting, or management conversations happen at open desks.
- One person regularly occupies a multi-person meeting room for a video call.
- Teams have acceptable room acoustics but still lack speech privacy.
- Call-heavy departments create predictable demand peaks.
What the Booth Should Do
For these scenarios, a one-person Sichtschutzkabine gives the speaker a defined place for calls, video meetings, and short confidential conversations. It should not be treated as a multi-person meeting room or an all-day private office. Longer deep-work sessions may require a work pod or another space designed around a longer stay.
The booth also needs to be usable. Acoustic privacy alone will not make a poorly ventilated, badly placed, or difficult-to-access booth successful. Facilities teams should review airflow, power, lighting, door swing, internal work surface, delivery route, and expected session length before choosing a model.
How Many Privacy Booths Does an Office Need?
There is no universal booth-to-employee ratio that works for every organization. Total headcount is a weak planning input when only part of the workforce is present and call behavior differs sharply by department.
B&H Ergonomics recommends starting with four questions:
- How many people are normally in the office on a typical busy day?
- How many private calls or video meetings happen at the same time during the peak period?
- Which departments generate those calls?
- How long does a typical booth session last?
Department mix should change the plan.
| Department or Work Type | Typical Booth Demand | Planning Adjustment |
|---|---|---|
| Vertrieb | Hoch | Add capacity for overlapping prospect and customer calls |
| Customer support or customer success | Hoch | Plan for repeated scheduled and unscheduled conversations |
| Recruiting and HR | Medium to high | Prioritize privacy for interviews and sensitive discussions |
| Finance, legal, and management | Mittel | Frequency may be lower, but privacy requirements can be higher |
| Engineering, design, or analysis | Low to medium | Fewer live calls; separate longer-focus needs from call-booth demand |
| Hybrid teams with heavy video use | Variabel | Measure the peak overlap created by scheduled remote meetings |
A 100-person office with ten sales representatives may need more call-booth capacity than a larger office where most employees do quiet individual work and private rooms are already available.
The most dependable method is to observe real peak behavior. Record meeting-room use by one person, hallway calls, booth queues, abandoned booth attempts, and average session length. Use that evidence for an initial deployment, then review demand after employees have had time to adopt the spaces.
Do not distribute booths evenly just to make a floor plan look balanced. Place more capacity near teams that generate more private conversations, while keeping units far enough from concentrated desk areas that booth entry, door movement, and waiting do not create a new distraction.
Why Whole-Booth Acoustic Evidence Matters
Acoustic claims become confusing when buyers compare different measurements as though they describe the same thing. Component ratings, laboratory speech-reduction results, factory measurements, and measurements taken in an installed office can answer different questions.
ISO 23351-1 covers the measurement of speech level reduction for furniture ensembles and enclosures. For booth procurement, that is more directly relevant than a vague decibel claim with no named method or tested configuration.
| B&H-Modell | ISO 23351-1 Result | B&H Factory Testing Under Controlled Conditions | Positionierung |
|---|---|---|---|
| Elite-S | Class A, 33 dB speech level reduction | 40-45 dB sound level difference | Higher acoustic-privacy priority |
| Flex-S | Class A, 30.7 dB speech level reduction | 37-42 dB sound level difference | Balanced acoustic privacy and cost control |
| Oasis-S | Not tested under ISO 23351-1; no ISO class or speech level reduction result | 32-37 dB sound level difference | Entry-level office privacy |
For Elite-S, B&H Ergonomics can provide the relevant Intertek acoustic report during project evaluation where applicable. Oasis-S has not been tested under ISO 23351-1, so its B&H factory-tested 32-37 dB sound level difference must not be presented as an ISO class or speech level reduction result. The ISO speech level reduction figures and B&H factory-tested sound level differences are not interchangeable. They use different measurement contexts and should remain separately labeled.
Acoustic results vary by test method, installation, site conditions, and measurement setup. Door seals, glazing, ventilation paths, floor level, assembly quality, placement, and surrounding activity can all affect the experience after installation.
Before accepting any booth claim, ask:
- Which exact model and configuration were tested?
- Which standard or internal method was used?
- Is the result third-party, factory-tested, or measured after installation?
- Does the quoted product match the tested door, glass, seals, and ventilation configuration?
- What conditions may reduce performance in the real office?
- Can the supplier provide model-specific acoustic evidence during project review?

When a Hybrid Strategy Works Better
Many offices should not choose between booths and panels at all. The better plan is often to assign each tool a clear job.
The U.S. General Services Administration’s workplace acoustic guidance describes acoustic comfort as a layered planning problem involving absorption, blocking, covering or masking, and workplace planning rather than one isolated product choice (GSA Sound Matters).
A practical hybrid strategy may include:
- Panels or ceiling treatment in reflective meeting and collaboration areas.
- Zoning that separates high-conversation and quiet-work neighborhoods.
- Privacy booths near sales, recruiting, support, and hybrid-meeting teams.
- Behavior rules that prevent booths from becoming informal all-day offices.
- Meeting rooms reserved for genuine group work instead of recurring solo calls.
- Utilization review after installation so capacity can be moved or expanded.
This approach avoids two expensive mistakes: installing panels and expecting confidentiality, or buying booths while ignoring a room-wide reverberation problem.
Need help sizing private-call space?
Prepare normal busy-day attendance, peak simultaneous call demand, department mix, session length, and delivery-route constraints before requesting options. That information helps B&H Ergonomics recommend a more realistic booth quantity and model shortlist.

Before requesting product options or approving a booth quantity, confirm:
- Normal busy-day office attendance.
- Peak simultaneous call and video-meeting demand.
- Department and job-type mix.
- Average and maximum session length.
- Higher-confidentiality zones such as HR or management.
- Placement near the teams that will use the booths.
- Door swing and circulation clearance.
- Available power and cable routing.
- Ventilation and fan-noise expectations.
- Delivery access through doors, corridors, elevators, and turns.
- Floor condition, leveling, and any relocation path.
- Model-specific acoustic evidence.
- Whether a pilot, phased rollout, or full deployment is more appropriate.
- A post-installation utilization review date.
A booth plan is ready when it connects a measured demand problem to a location, quantity, model requirement, and review process. Buying a visually appealing enclosure without completing those steps can leave one department waiting while another booth remains underused.
FAQ
Are acoustic panels enough for private office calls?
Usually not. Acoustic panels can reduce reflections and improve room comfort, but they do not create an enclosed boundary around the speaker. If employees need a reliable place for private calls, video meetings, or sensitive conversations, a booth or another enclosed space is usually required.
Wie viele Sichtschutzkabinen braucht ein Büro?
Start with normal busy-day attendance and peak simultaneous private-call demand, then adjust for department mix and session length. Sales, support, recruiting, and video-heavy teams generally require more booth access than departments with fewer live calls. Review actual queues and meeting-room conflicts after deployment instead of relying on a universal employee ratio.
Is a privacy booth completely soundproof?
No. A privacy booth can improve speech privacy and reduce distraction, but it should not be described as completely soundproof. Performance depends on the tested model, measurement method, assembly, seals, ventilation paths, installation, placement, and surrounding office conditions.
Should sales teams have more booths than other departments?
Often, yes. Sales teams commonly generate more simultaneous external calls than lower-call departments, so equal booth distribution can create avoidable queues. Quantity and placement should follow observed call demand rather than giving every department the same allocation.
