Open offices promote communication and flexibility, yet their design brings a major challenge: noise. Conversations, phone calls and background sounds can quickly affect focus and well-being. Achieving both collaboration and efficiency requires a strategic approach to acoustic comfort.
Acoustic challenges of open offices
In open spaces, sound travels freely. The lack of partitions or absorbent materials increases reverberation, leading to a continuous “buzz” that makes it hard to concentrate. The goal is not silence, but control—reducing reflections and containing noise in specific zones.
Main sources of noise
- Simultaneous conversations and meetings.
- Equipment sounds from printers, keyboards and ventilation.
- Hard surfaces reflecting sound waves and amplifying echoes.
Impact on health and performance
Excessive noise causes stress and fatigue. The brain constantly filters unwanted sound, which reduces focus and increases cognitive load. Studies show that poor acoustics can lower productivity by up to 10%.
Creating a balanced sound environment
The key is a mix of absorbing materials, zoning strategies and acoustic furniture. Good design maintains liveliness while preventing disturbance between work areas.
- Use acoustic ceilings and wall panels to reduce reverberation.
- Add textile elements such as curtains or carpets to soften reflections.
- Create quiet zones for focused work.
- Separate desks with sound-absorbing partitions.
Best acoustic design practices
- Mix reflective and absorbent surfaces for optimal balance.
- Locate noisy devices away from quiet areas.
- Favor modular acoustic ceilings and diffusing elements.
- Use plants and soft furnishings as natural sound filters.
A holistic view of comfort
Acoustics are a major part of workplace well-being, just like lighting and ergonomics. A well-balanced soundscape boosts collaboration, creativity and serenity in everyday work life.

FAQ
Why is noise more disturbing in open offices?
Because sound spreads freely without barriers or absorbent materials, amplifying every voice and reflection.
Which materials improve acoustic comfort?
Textile finishes, PET panels and acoustic ceilings effectively reduce reflections.
Can an existing office be improved without renovation?
Yes. Adding wall panels, ceiling absorbers and decorative acoustic elements can make a big difference.
What is the ideal reverberation time for offices?
Typically between 0.55 and 0.77 seconds depending on the type of activity.
