How noise costs your business more than you might realise
Most people who work in an open-plan office have a version of the same story. It starts with a conversation between two colleagues nearby. Before long, you’ve lost your train of thought, given up on the email you were writing, and resigned yourself to the fact that focus isn’t happening this morning.
And while open-plan office noise is often treated as a minor frustration, in fact it’s a significant business problem. The research on workplace noise is clear, consistent, and worth taking seriously: noise in open-plan offices affects concentration, increases stress, accelerates fatigue and pushes good people toward the exit. These aren’t soft costs. They show up in output, in team culture and in the cost of finding and keeping staff.
For Queensland businesses in corporate offices, professional services firms and government workplaces, understanding the real impact of noise is the first step toward addressing it.
What the research tells us about open-plan office noise
The numbers on noise and productivity are striking. Research shows that workers lose an average of 86 minutes per day to noise-related distractions. In an office of 20 people, that’s the equivalent of nearly three full-time employees losing their entire day to noise, every single day.
A 2024 study involving workers in Australia, the UK and the United States found that 69% of employees report dissatisfaction with the noise levels at their primary workspace. Of those surveyed, 44% said their employer does nothing to address the problem, leaving individuals to find their own coping strategies.
The interruption cycle compounds the damage. Research from the University of California, Irvine found that after any interruption, it takes an average of 23 minutes and 15 seconds to fully return to the original task. For knowledge workers doing complex, sustained thinking, that’s a serious problem. Someone interrupted four times in a morning loses close to two hours of focused work time before lunch.
The problem of concentration in open-plan offices
The most disruptive noise in any open-plan office isn’t ambient background sound; it’s intelligible speech. When a conversation nearby is just clear enough to follow, the brain involuntarily attempts to process it, even when the listener is trying to focus on something else. This is an automatic response that can’t simply be switched off through willpower.
This explains why headphone use in open offices has nearly doubled in recent years. By 2025, around 41% of office workers regularly used noise-blocking headphones, up from 23% in 2022. Workers aren’t listening to podcasts. They’re trying to create a barrier between themselves and the acoustic environment around them.
The fact that so many workers are self-managing a noise problem tells us something about how pervasive it is. It also reveals that the problem isn’t being solved at the source.
The effect of excess noise on wellbeing and fatigue
Sustained workplace noise doesn’t just affect workers’ concentration. Extended exposure to noise at levels common in open-plan offices has been shown to contribute to elevated cortisol levels, increased blood pressure, and higher reported rates of stress and burnout.
Fatigue is particularly significant. A noisy working environment requires continuous effort from the brain to filter out unwanted sound. Over the course of a day, that effort accumulates. Employees finish the workday feeling more drained than the work itself would justify. The environment is doing work on their nervous systems, even when they’re not consciously aware of it.
For Queensland businesses running large open-plan floors in Brisbane, the Gold Coast or the Sunshine Coast, where the return to office has brought significant numbers of staff back to shared spaces, this fatigue factor is worth understanding. People who come to the office and find it exhausting are less likely to want to keep coming back.
Staff retention and the noise connection
One finding from workplace acoustics research that deserves more attention: workers in the noisiest office environments are significantly more likely to say they intend to leave their role within the next six months. Research from Oxford Economics made this connection directly, linking acoustic discomfort to higher turnover intention.
The cost of replacing an employee is substantial. Depending on the role, estimates range from 50% to over 200% of the position’s annual salary once you factor in recruitment, onboarding and lost institutional knowledge. If even a modest proportion of staff turnover can be linked to a poor acoustic environment, addressing the acoustics is worth the investment.
This is particularly relevant in Queensland’s professional services sector, where competition for skilled professionals in Brisbane and beyond remains real. Staff who feel comfortable and supported in their workplace are more likely to stay. Staff who find their workplace fatiguing and difficult are more likely to look for alternatives.
Why open-plan offices amplify noise problems
Thanks to their design, open-plan offices are acoustically challenging. They’re built around hard surfaces that reflect sound: polished concrete, glass, plasterboard, large windows. The layout that maximises collaboration and visibility also maximises noise exposure: the absence of walls means sound travels freely across the floor.
This doesn’t mean open-plan office layouts are the wrong choice. They offer real benefits for team communication, space efficiency, and workplace culture. The issue is that acoustic design needs to be considered alongside the physical design. A beautiful open-plan office built without acoustic treatment is a space that looks good but sounds hard.
The answer isn’t to install walls everywhere and destroy an open-plan layout. It’s to introduce sound-absorbing surfaces in the right places: ceiling panels to capture reflected sound, wall treatment in collaboration zones, and freestanding acoustic dividers to reduce the direct path of sound between workstations.
Practical steps toward creating a quieter office
When you’re thinking about addressing noise in your business’s current space, the practical options are wider than you might assume. Acoustic treatment doesn’t require a full office renovation; products like the Calando acoustic panel can be installed on existing ceilings and walls with minimal disruption. Freestanding dividers can be repositioned as the office layout changes.
The most effective starting point is identifying where the biggest problems are. Which areas generate the most noise? Where do employees go when they need to concentrate? Are there specific times of day when noise levels spike?
The answers to these questions should shape your acoustic treatment plan to ensure investment goes where it will have the greatest impact.

Avenue Interior Systems has helped Queensland businesses across a range of sectors improve their acoustic environments without major works. In most cases, targeted acoustic treatment in the highest-impact areas delivers a noticeable improvement in how the office feels to work in.
The cost of noise in your office isn’t always visible in a spreadsheet. It shows up in the quality of work being done, in how people feel at the end of the day, and in whether your best people choose to stay. When you look at it that way, acoustic design stops being a “nice-to-have” and becomes a straightforward business decision.
