Invisible Comfort

Materials and strategies to improve acoustics in workspaces

“In life, as in art, it is hard to say anything as effective as silence.”

Ludwig Wittgenstein

A well-designed office is something you can feel even before you really see it. There is a quality in the air, hard to define but immediately clear, that makes the difference between a productive workspace and one where energy and focus quickly fade. Sound plays a big role in this experience. The acoustics of the workplace is still one of the most overlooked aspects of interior design. Companies often invest in finishes, lighting and ergonomic furniture. Acoustic comfort, however, is usually treated as a secondary element, something to solve at the end of the project. But this is a mistake in perspective, even before it becomes a design mistake.

Separation alone is not enough

Today’s offices are open, dynamic, and flexible: open spaces, collaborative areas, casual zones, and transparent meeting rooms. This kind of layout encourages interaction but also creates a complex soundscape, overlapping conversations, phones ringing, footsteps, and echoes.

The natural solution is to separate areas physically. And yes, it helps, but it’s only part of the answer. A well-designed partition already goes a long way: it reduces noise between zones, defines different work areas, and creates the right conditions for focused or collaborative activities. Systems like Ritmica Alluminio by Etoile, aluminum partitions with single or double glass or solid panels, do this quietly and efficiently, while keeping the space stylish and visually open.

The space reflects what it doesn’t absorb

Every hard surface, drywall ceilings, resin floors, plastered walls, reflects sound instead of absorbing it. These reflections add up, creating a reverberant environment that tires people without them even realizing why. The solution isn’t simply adding silence, it’s about distributing materials that break this chain of reflections throughout the space.

PET panels, made from recycled plastic bottles, absorb mid and high frequencies without requiring structural changes. Mounted on ceilings or walls, their versatility has even turned them into design features: acoustic function and aesthetic appeal in one. A similar effect comes from perforated or laminated wood panels. Wood transforms reflections into diffusion, softening the sound and making it less harsh. The result is a perceptual quality closer to a home environment, the very feeling that many contemporary workspaces strive to achieve.

The floor matters too

Acoustic carpet (and more contemporary options like tatami-style flooring) is one of the most effective and often underrated ways to reduce footstep noise and lower-level reverberation, the sound range where most conversations happen. Its comeback is driven by function, not nostalgia. No other material delivers the same performance with such ease.

Suspended surfaces, textiles, and objects

Acoustic curtains are often underestimated. Made with multi-layer technical fabrics, they reduce lateral sound transmission, especially in rooms with large windows that would otherwise act as reflective surfaces. They also help modulate natural light: one solution, two problems solved at once.

Desk dividers lower distractions between colleagues without breaking up the space. When made from sound-absorbing materials—technical felt, pressed wool, or covered foam—their effectiveness goes far beyond just visual screening.

Even lighting can play a role when designed thoughtfully. Some office pendant lights incorporate absorbing materials into their structure, combining illumination and acoustic function in a single object that already belongs to the room. It’s the kind of integrated solution every design should aim for.

A matter of layers

Acoustic comfort is never achieved with a single solution. It comes from layering choices at different levels: reducing noise between areas, controlling internal reverberation, and managing distractions at individual workstations. None of these levels works on its own, each solves only part of the problem.

When all three work together, and when this orchestration is planned from the start rather than fixed afterward, the space gains a quality that’s hard to pin down to any one element. It’s felt as a whole. People work better without even knowing why. A well-designed office isn’t just quiet. It’s a space where sound is controlled, balanced, and made compatible with the various activities happening within it.

And often, the clearest sign of good design is what you don’t hear.
