Open-plan offices raise stress 34%. What actually helps

Open-plan office noise raises your physical stress response by 34%, a controlled 2021 study found. It also cuts how many words you can hold in your head at once, a separate study found. Neither effect depends on how disciplined you are.

If you moved to a shared floor and your focus dropped, the room is the reason. It isn't you. This article covers the research, why noise hits harder if you're dyslexic, and four fixes that need no diagnosis.

What the noise actually does to your brain

Researchers at Griffith University tested people in a simulated open-plan office. They played real office sounds: talk, ringing phones, keyboards, a printer. Stress and sweat response rose by 34% against a quiet room (Sander et al., Journal of Management and Organization, 2021).

A separate study ran people through two hours of memory tasks. One session used low background noise, one used typical open-plan noise. People remembered fewer words after working in the noisy version (Jahncke et al., Journal of Environmental Psychology, 2011).

Negative mood also rose by 25% in the noisy condition of the 2021 study. Neither study selected people for dyslexia. The effect is general, not something unique to a dyslexic brain.

The 2021 study only ran the noise for eight minutes at a time in a lab. A real office runs that same noise for eight hours a day, five days a week. The researchers expected the true effect on stress and mood to be larger over a full day, not smaller.

So what for you: if concentration got worse the day you moved desks, that's a measured physical response to noise. It isn't a focus problem you need to push through alone.

Why it lands harder if you're dyslexic

Dyslexia uses extra working memory for reading, writing, and following speech. A 2025 study of 400 UK workers found dyslexia raises the odds of memory and attention slips at work. Source: Smith-Spark and Huang, Behavioral Sciences, November 2025.

Reading a document while someone talks nearby uses that same stretched resource twice over. No study has measured the exact size of that extra cost. What we do know, from sensory-processing research, points the same way.

Less spare working memory, plus noise that eats more of it, is a real and measurable double demand. That combination is what makes an open-plan floor feel harder to think in, even on an ordinary day.

Background speech is worse than steady noise for this reason. Memory researchers call it the irrelevant speech effect. Speech that changes pitch breaks short-term word recall far more than a steady hum.

Air conditioning is a steady hum; a phone call is not. This finding dates to Colle and Welsh, 1976, and has been replicated many times since.

A colleague's phone call breaks your working memory more than the printer does. It changes pitch and rhythm. The printer doesn't.

So what for you: you don't need a formal sensory-processing diagnosis to justify asking for less noise. The working-memory research on its own supports the request.

Four fixes that don't need disclosure

None of these four fixes require telling anyone you're dyslexic. Ask for them as an ordinary productivity request, the same way any colleague might.

• Noise-cancelling headphones. Block a large share of the talk and printer noise that the 2021 study measured. Many employers will simply buy a pair if you ask; UK readers can also claim through Access to Work.
• Two protected quiet hours. Block the same two hours daily on your calendar for reading, writing, or drafting. Naming the block "focus time" gets it respected far more often than leaving it unlabelled.
• A better desk position. Ask to move away from walkways, the printer, or the phone bank. Fewer passing conversations means fewer working-memory resets during the day.
• Batched interruptions. Ask colleagues to message rather than interrupt live, then check messages at set times. This turns constant small noise spikes into two or three planned breaks.

None of this needs a formal meeting. A short chat with your manager, framed as "I focus better with fewer interruptions", usually gets a quick yes. Frame it as a productivity request, not a health disclosure.

Fix	Typical cost	Who to ask
Noise-cancelling headphones	£0 to £300	Line manager or IT
Two protected quiet hours	Free	Line manager, calendar block
Desk away from noise	Free	Line manager or office manager
Batched interruptions	Free	Team, shared agreement

A real example

A dyslexic operations manager moved from a private office to an open floor after a restructure. Board papers that took 90 minutes to draft in the old office were taking three hours on the new floor.

They asked for three things in one short email. Noise-cancelling headphones, a desk away from the coffee machine, and two blocked morning hours for drafting.

The manager agreed to all three within a week, with no diagnosis mentioned.

Drafting time dropped back to under two hours within a month.

So what for you: start with the desk move and the headphones. Both usually cost nothing and need no formal process.

When to put it in writing

Most desk-noise requests get solved with a short conversation and a headset. If yours gets refused, or agreed verbally and then never actioned, that's the point to put it in writing.

Some people worry that asking marks them out as difficult. In practice, a calm, specific request usually lands better than a vague complaint. It gives your manager something concrete to act on.

Naming the specific problem, noise breaking your concentration during report writing, works better than a vague "it's too loud". The reasonable adjustments builder turns your specific problem into a conversation plan and a draft email, in about two minutes.

In the UK, Access to Work can fund noise-cancelling headphones, screens, or a desk change. New starters get 100% funding for their first six weeks in a role, with no employer contribution needed. After that, standard cost-sharing applies, capped at £69,260 a year for 2026-27 (DWP Access to Work guidance, 2026).

The Access to Work calculator estimates what you could claim before you apply. If you haven't disclosed dyslexia at all yet, the disclosure decision guide covers when naming it formally is worth it.

US employees have the same option under the ADA. Name the specific noise-related difficulty in writing. Then ask for a reasonable accommodation such as headphones, a desk move, or a partition (Job Accommodation Network, askjan.org).

The process is the same wherever you work: specific problem, specific fix, on paper.

So what for you: a verbal agreement is a fine place to start. Written confirmation is what protects you if the noise problem, and the fix, gets forgotten in a month.

What this means for you

If your focus has dropped since you moved desks, don't treat it as a personal failing. Ask for headphones and a desk change this week. Ask again in writing if it's already been raised once and ignored.

Ask your line manager before going to HR. Most noise fixes are cheap enough that one manager can approve them without a formal accommodations process.

That single email is the strongest evidence you'll have. It matters if the noise problem, or the promised fix, quietly disappears in a few months.

So what for you: try the free fix first, a desk move. Save the paid fix, a formal Access to Work claim, for after that.
