When a company describes its own office as noisy, the first hypothesis is usually the acoustics of the space. High ceilings, exposed slabs, glass, concrete, hard floors and a lack of absorbent elements really are part of the problem: they make sound linger and travel further than it should.
So it is natural that the search begins with acoustic treatment. Panels, ceilings, carpets, curtains and booths are the visible answer to a diffuse complaint — and in many cases they are indeed part of the solution.
What usually surprises is the partial result. The work is done, reverberation drops, the space feels better in the first week — and people still report that they cannot concentrate. This happens because the sound environment of an office is not formed by surfaces alone. It is formed by what people do, where they do it and at what time.
What bothers people in an office is almost never the volume
There is an important difference between a loud office and a noisy one. A factory is loud: high, constant sound levels. An office often has modest sound levels and is still experienced as unbearable by anyone who needs to think.
The reason is well described in the literature on auditory distraction: the sound that most disturbs intellectual work is not the loudest, it is the most intelligible. Speech from another person, when it can be understood, competes directly with the same mental processes used to read, write, calculate and organize ideas. Constant air conditioning, at the same sound level, disturbs far less.
This is the first inversion an honest diagnosis has to make. The useful question is not "is it too loud?". It is "what is being understood by people who should not be hearing it?".
Where the sound of an office comes from
On a typical corporate floor, the sound environment is formed by layers that are rarely examined together:
- work conversations between colleagues, at desks, in corridors and in the pantry;
- phone calls and video calls made in open positions;
- quick meetings that happen wherever there is room, not where they should happen;
- air conditioning, ventilation, equipment, printers and circulation;
- notifications, alarms, lift chimes and system alerts;
- the surroundings: traffic, construction work, façade, slab and neighbors on the floor.
Each layer, on its own, usually seems acceptable. The discomfort appears in the sum — and in the coincidence. A call next to an area of focused work is not a volume problem: it is a problem of position and timing.
Video calls changed the office, and almost no one redesigned the layout
Most offices in use today were planned before video calls became routine. The layout assumed face-to-face conversation, occasional phone calls and meetings held in meeting rooms. Today a single person, sitting in an open position, speaks out loud for hours — and no design anticipated that behavior.
There is also a detail well known to those who study distraction: hearing half of a conversation tends to disturb more than hearing a whole one. The brain tries to complete what is missing. That is why a single call can disorganize an entire area, even when no one is shouting.
Hybrid work added another layer: occupancy is no longer stable. The same floor may be empty on Monday and full on Wednesday. An environment designed for average occupancy starts to work poorly at both extremes.
