Only 33% of office workers were satisfied with noise levels in 2024, down from 37% at the height of the pandemic, even though 70% say noise levels matter to their work (Leesman, Noisy spaces, quiet consequences, March 2026, N=601,570). The problem is structural rather than new: in 20 years of Center for the Built Environment surveys, sound privacy was the single most disliked feature of office buildings, with 54% of occupants dissatisfied. When two corporate headquarters went open-plan, face-to-face interaction fell by about 70%, the opposite of what the redesign promised. And a Danish national survey linked open-plan offices of more than 6 people to 62% more sickness absence days than single offices. We aggregated data from Leesman, the Center for the Built Environment at UC Berkeley, the European OFFICAIR study, Bernstein and Turban’s field studies in the Philosophical Transactions of the Royal Society B, Gensler and more than a dozen peer-reviewed studies indexed in Europe PMC; the broader environmental picture is in our noise pollution statistics.
TL;DR
- Noise satisfaction fell to 35% in 2023 and 33% in 2024, with early 2025 data at 36% (Leesman, Noisy spaces, quiet consequences 2026).
- 70% of employees say noise levels are important, but only 35% are satisfied (Leesman 2026).
- 54% of building occupants are dissatisfied with sound privacy, the worst-rated item (CBE occupant surveys, Graham et al. 2021).
- 47% of European office workers are dissatisfied with noise inside the building (OFFICAIR study, Sakellaris et al. 2016).
- Face-to-face interaction dropped about 70% after moves to open offices (Bernstein and Turban, Phil Trans R Soc B 2018).
- 99% of surveyed employees said office noise impaired their concentration (Banbury and Berry, Ergonomics 2005).
- Lack of privacy predicts acoustic dissatisfaction 25% more strongly than noise disturbance (Yadav et al., JASA 2025).
- Open-plan offices of more than 6 people: 62% more sickness absence days than single offices (Pejtersen et al., 2011).
- Only 39.8% of activity-based office workers have sufficient access to quiet workspaces (Tulenheimo-Eklund et al., J Occup Health 2025).
- 32% of open-plan workers cope with headphones or music vs 22% in shared offices (Di Blasio et al., IJERPH 2019).
- Two-thirds of office workers ‘hack’ their workspace to compensate for performance gaps (Gensler Global Workplace Survey 2026).
1. Noise Satisfaction Benchmarks: The Lowest-Rated Part of the Office
Every large occupant database lands on the same finding: noise and speech privacy are the weakest link in the office. Leesman’s noise satisfaction score dropped to 35% in 2023 and fell again to 33% in 2024, despite having reached 37% at the height of the pandemic (Leesman, Noisy spaces, quiet consequences, March 2026). The timing matters: the slide coincides with return-to-office policies refilling desks, which suggests many offices were never acoustically tuned for full occupancy after 2020.
The gap between importance and delivery is what makes noise expensive. Leesman reports that 70% of employees rate noise levels as important but only 35% are satisfied, and even in its best-performing Leesman+ certified workplaces satisfaction sits at just 45%. Agreement that the workplace ‘enables me to work productively’ is 46 percentage points lower among employees who are not satisfied with noise, and agreement that ‘working here has a positive impact on my overall wellbeing’ is 45 points lower.

Context note: Leesman scores are the share of respondents satisfied with each feature in its standard survey; the 2025 figure is described by Leesman as an early indication, not a full-year result.
2. Sound Privacy: The Single Worst-Rated Feature in Building Surveys
Leesman is not an outlier. In 93,662 occupant responses from 897 buildings, 54% were dissatisfied with sound privacy, more than with temperature (39%) or noise level (34%) (Graham, Parkinson and Schiavon, Lessons learned from 20 years of CBE’s occupant surveys, Buildings and Cities 2021). The same paper finds acoustical quality has the largest negative impact on self-reported productivity, with 39% dissatisfied. Ease of interaction, the reason open plans are built, is the best-rated item at 75% satisfied, which neatly states the trade-off: the layout delivers the conversation and then charges everyone else for overhearing it.
Europe shows the same pattern with a different instrument. The OFFICAIR study of 7,441 workers in 167 buildings across 8 countries found 47% dissatisfied with noise inside the building and 51% dissatisfied with privacy, and overall noise satisfaction was the strongest indoor environmental predictor of overall comfort, with an odds ratio of 2.05 (Sakellaris et al., OFFICAIR study, IJERPH 2016). In a newer field study of 349 occupants in 28 open-plan offices, lack of privacy contributed 25% more than noise disturbance to predicting acoustic dissatisfaction, and medium-sized offices were rated worse than offices of 50 or more occupants (Yadav, Kim, Hongisto, Cabrera and de Dear, Journal of the Acoustical Society of America 2025).

| Field sample, acoustic dissatisfaction model | 349 occupants in 28 offices | Yadav et al., JASA (2025) |
Context note: the CBE database spans 1999 to January 2020 (most recent available data: Graham et al., 2021); 68% of its respondents were satisfied with their workspace overall. Workspace types in the database were 25.5% high-partition cubicles, 22.2% low-partition cubicles, 20.3% private offices, 9.5% open desk areas and 5.8% shared spaces. OFFICAIR had a response rate of about 40%, and 78% of its respondents worked in shared rooms or open-plan offices.
3. The Collaboration Paradox: Less Talking, More Typing
The business case for open plans rests on interaction, and the most rigorous field test found the reverse. When two corporate headquarters moved to open layouts, face-to-face interaction fell by about 70% while electronic messaging rose (Bernstein and Turban, The impact of the ‘open’ workspace on human collaboration, Philosophical Transactions of the Royal Society B, 2018). In the first study, 52 employees wearing sociometric badges went from 5.8 hours of face-to-face interaction per person per day to 1.7 hours, a 72% drop, while sent emails rose 56% and instant messages 67%.
The authors read this as social withdrawal: when everyone can hear everything, people stop talking out loud. That is consistent with the privacy findings above, and with a 2023 systematic review that screened 429 papers published between 2005 and 2022, kept 46 empirical studies and concluded that open-plan offices impose a ‘tax on productivity’ that outweighs their real-estate savings, while single offices supported the best individual and organizational performance for knowledge workers (Gerlitz and Hulsbeck, Management Review Quarterly 2023).
| Metric | Value | Source |
|---|---|---|
| Face-to-face interaction, study 1 (52 employees) | 5.8 to 1.7 hours per person per day (-72%) | Bernstein and Turban (2018) |
| Emails sent, study 1 | +56% | Bernstein and Turban (2018) |
| Instant messages, study 1 | +67% messages, +75% words | Bernstein and Turban (2018) |
| Face-to-face interaction, study 2 (100 employees) | -67% to -71% | Bernstein and Turban (2018) |
| Email, study 2 | +22% to +50% | Bernstein and Turban (2018) |
| Dyads with less face-to-face time, study 2 | 643 of 1,830 | Bernstein and Turban (2018) |
| Office-concept review | 429 papers screened, 46 empirical studies included (2005-2022) | Gerlitz and Hulsbeck, MRQ (2023) |
Context note: the Bernstein and Turban studies covered two organizations and measured interaction volume, not output quality; most recent available data for this design is the 2018 paper. The two study-2 ranges come from different regression models, as published.
4. Why Speech Is the Problem: Cognitive Performance Under Irrelevant Talk
Open offices are rarely loud in the hearing-damage sense. A French questionnaire study notes that levels in tertiary-sector open spaces rarely exceed 65 dB(A), yet most of its 237 respondents rated ambient noise as high and named intelligible colleague conversations as the main annoyance (Pierrette et al., Ergonomics 2015). The problem is meaning, not decibels, which is why office acoustics is a different field from the occupational exposure covered in our construction worker hearing loss statistics.
In a field survey of 88 employees, 99% reported that their concentration was impaired by components of office noise, with no evidence of habituation (Banbury and Berry, Ergonomics 2005; most recent available data). Laboratory work explains why. Hongisto’s model in Indoor Air (2005) notes performance decrements of 4-45% depending on the task, with performance starting to fall once the speech transmission index (STI) exceeds 0.2 and the largest decrease reached once it exceeds 0.60. In a test with 37 participants at 48 dBA, working memory, serial recall and prior-knowledge tasks all deteriorated at the highest speech intelligibility (STI 0.65) (Haka et al., Indoor Air 2009), and in 4-hour sessions with 36 subjects proofreading suffered under speech but not under continuous noise at the same 48 dBA (Venetjoki et al., Ergonomics 2006).
| Metric | Value | Source |
|---|---|---|
| Employees reporting concentration impaired by office noise | 99% (88 employees, 2 sites) | Banbury and Berry, Ergonomics (2005) |
| Task performance decrements from speech in prior studies | 4-45% depending on the task | Hongisto, Indoor Air (2005) |
| STI at which performance starts to fall | Above 0.2 (largest decrease above 0.60) | Hongisto, Indoor Air (2005) |
| Speech intelligibility conditions tested at 48 dBA | STI 0.10, 0.35 and 0.65 (37 participants) | Haka et al., Indoor Air (2009) |
| Work rate under open-plan noise at 55 dBA | -3%, with increased fatigue | Witterseh, Wyon and Clausen, Indoor Air (2004) |
| Typical open-space level and respondents | Rarely above 65 dB(A); 237 respondents | Pierrette et al., Ergonomics (2015) |
| Relocation to open plan (31 workers) | Self-rated performance loss from noise doubled | Kaarlela-Tuomaala et al., Ergonomics (2009) |
Context note: these are mostly laboratory and small field studies from 2004 to 2015 (most recent available data); task sensitivity varies, and Jahncke (Noise and Health 2012) found tasks relying on episodic short-term memory and rehearsal most vulnerable to irrelevant speech. Witterseh et al. (Indoor Air 2004) combined noise with moderate heat stress.
5. Stress, Health and Sick Leave
The cost of distraction shows up in physiology and absence records, not just survey scores. A Danish national survey of 2,403 office workers found that, compared with single offices, open-plan offices of more than 6 people were associated with 62% more sickness absence days, 2-person offices with 50% more and 3-6 person offices with 36% more (Pejtersen, Feveile, Christensen and Burr, Scandinavian Journal of Work, Environment and Health 2011). A 2023 meta-analysis of 5 studies and 13,277 participants found an odds ratio of 1.27 (95% CI 0.99-1.54) for sick leave in small open-plan offices of 4 to 9 people versus cell offices (Mauss et al., Industrial Health 2023).
The mechanisms are visible in controlled studies. Forty female clerical workers exposed for 3 hours to low-intensity noise simulating an open office showed elevated urinary epinephrine and motivational deficits afterward (Evans and Johnson, Journal of Applied Psychology 2000). In a cross-sectional survey of 1,078 workers, physical symptoms such as tiredness and headaches attributed to irrelevant speech were reported by 9% in open-plan offices versus 4% in shared offices (Di Blasio et al., IJERPH 2019).
| Metric | Value | Source |
|---|---|---|
| Extra sickness absence, open plan (more than 6 people) vs single office | +62% | Pejtersen et al. (2011) |
| Extra sickness absence, 2-person and 3-6 person offices | +50% and +36% | Pejtersen et al. (2011) |
| Sick leave odds, small open-plan (4-9 people) vs cell office | OR 1.27 (95% CI 0.99-1.54) | Mauss et al., Industrial Health (2023) |
| Sick leave odds, open plan with 4 or more colleagues | OR 1.24 (95% CI 0.96-1.51) | Mauss et al., Industrial Health (2023) |
| Meta-analysis size | 5 studies, 13,277 participants | Mauss et al., Industrial Health (2023) |
| Physical symptoms from irrelevant speech | 9% open-plan vs 4% shared offices | Di Blasio et al., IJERPH (2019) |
| Stress named as main symptom | 6% open-plan vs 4% shared offices | Di Blasio et al., IJERPH (2019) |
| Office noise exposure and stress hormones | Elevated urinary epinephrine after 3 hours (40 workers) | Evans and Johnson (2000) |
Context note: the sick-leave studies are observational and cannot separate acoustics from infection spread or job type; the meta-analysis confidence interval touches 1.0, as published. In a lab study of 35-minute exposure at Leq 65 dBA, office noise raised perceived exertion but not physiological stress reactions (Kristiansen et al., 2009), so short exposures and full workdays should not be conflated.
6. Who Is Hit Hardest: Focus Work and Hearing Loss
Distraction is not distributed evenly. 89% of employees say individual focused work is an important workplace activity (Leesman, 2026), and the employees who do the most of it suffer the most. In a Swedish public-sector study of activity-based offices, employees with 20-40 hours a week of concentration-demanding tasks reported productivity 0.74 points lower than the lowest-demand group, plus higher noise disturbance and privacy concerns; dissatisfaction with premises and privacy explained 62% of productivity variance (Warme, Lofstrand and Vinberg, Industrial Health 2026).
People with hearing loss face a second penalty. In a simulated open office, 20 hearing-impaired participants were more affected by high (60 dB) noise than 18 normal-hearing participants (Jahncke and Halin, Noise and Health 2012). A 2026 laboratory study of 46 participants with simulated hearing loss found that hearing aids made the open-office sound environment feel more noisy (4.8 vs 3.1) and more annoying (4.4 vs 2.7), because they amplify the irrelevant speech too (Brocolini et al., Noise and Health 2026). Hearing that tests normal can still struggle with speech in noise, as covered in our hidden hearing loss statistics.
| Metric | Value | Source |
|---|---|---|
| Employees rating focused work as important | 89% | Leesman, Noisy spaces, quiet consequences (2026) |
| Productivity gap, 20-40 h vs 0-9 h weekly focus work | 0.74 points lower | Warme et al., Industrial Health (2026) |
| Productivity variance explained by premises and privacy dissatisfaction | 62% | Warme et al., Industrial Health (2026) |
| Swedish study response rates | 75% (450 of 600) and 71% (320 of 450); 130 in final panel | Warme et al., Industrial Health (2026) |
| Hearing-impaired vs normal-hearing participants, 60 dB vs 30 dB noise | 20 vs 18; hearing impaired more affected | Jahncke and Halin, Noise and Health (2012) |
| ‘Noisy’ rating with vs without hearing aids | 4.8 vs 3.1 | Brocolini et al., Noise and Health (2026) |
| ‘Annoying’ rating with vs without hearing aids | 4.4 vs 2.7 | Brocolini et al., Noise and Health (2026) |
Context note: the Brocolini study used normal-hearing participants with simulated moderate hearing loss and found no significant change in short-term task performance, so the result is about perceived burden and effort, not measured output.
7. What Works: Quiet Rooms, Layout and Coping
The fixes are known; supply is the problem. Only 39.8% of 971 Finnish activity-based office workers reported sufficient access to quiet workspaces, while 56.0% said access was varying and not good enough (Tulenheimo-Eklund et al., Journal of Occupational Health 2025). Quiet rooms change outcomes: when two organizations moved from private to open-plan offices, perceived distractions rose in both, but negative effects on environmental satisfaction, collaboration and stress emerged only in the office with few quiet rooms (Haapakangas et al., Journal of Environmental Psychology 2018).
Layout is the cheapest lever. ISO 3382-3 target values for good open-office acoustics are a spatial decay rate D2,S above 8 dB, a speech level at 4 m below 48 dB(A) and a distraction distance below 5 m; in modeled and field tests, face-to-face desk layouts produced distraction distances of 15.6 to 21.3 m, the worst grade, versus 10.7 m for parallel layouts (Lee and Haan, Heliyon 2024). Without design fixes, workers improvise: Gensler’s survey of 16,459 office workers in 16 countries found two-thirds ‘hacking’ their workspace and one in four resorting to DIY fixes for ergonomics, temperature or visual privacy, with noise listed among unresolved challenges (Gensler Global Workplace Survey 2026). Masking sound is one design response, covered in our white noise and sound conditioner statistics.
| Metric | Value | Source |

| Sufficient access to quiet workspaces (971 workers) | 39.8% (56.0% varying, 4.3% none) | Tulenheimo-Eklund et al., J Occup Health (2025) |
| Workers using nonassigned workstations | 89.2% | Tulenheimo-Eklund et al., J Occup Health (2025) |
| Relocation surveys, before and after | N=65 and 64 before, 135 and 71 after | Haapakangas et al., J Environ Psychol (2018) |
| ISO 3382-3 target values | D2,S above 8 dB; Lp,A,S,4m below 48 dB(A); rD below 5 m | Lee and Haan, Heliyon (2024) |
| Distraction distance by layout | Face-to-face 15.6-21.3 m; parallel 10.7 m; crossed 11.0 m; orthogonal 11.8 m | Lee and Haan, Heliyon (2024) |
| Headphones or music as coping strategy | 32% open-plan vs 22% shared offices | Di Blasio et al., IJERPH (2019) |
| Open-plan workers willing to lower voice on monitor feedback | About 70% (shared offices about 60%) | Di Blasio et al., IJERPH (2019) |
| Workers ‘hacking’ their workspace | Two-thirds (16,459 surveyed, 16 countries) | Gensler Global Workplace Survey (2026) |
Context note: activity-based offices are not automatically worse. When employees moved from a traditional open plan to an activity-based office, satisfaction with auditory privacy and background noise increased significantly, though team communication suffered (Rolfo, Eklund and Jahncke, Ergonomics 2018).

- Data watch: Survey benchmarks are not interchangeable. Leesman reports the share satisfied with ‘noise levels’ (601,570 respondents, 2022 to 2025 Q3), CBE pools 93,662 responses from 1999 to January 2020 (most recent available data), and OFFICAIR surveyed 167 European buildings in a study published in 2016, so the 33%, 54% and 47% figures measure different questions and periods. Much of the cognitive evidence comes from laboratory and small field studies published 2000-2015 (most recent available data). The sick-leave meta-analysis confidence interval for small open-plan offices (0.99-1.54) touches 1.0. Kim and de Dear’s 2013 paper on the privacy-communication trade-off (Journal of Environmental Psychology) and Frontczak et al. (Indoor Air 2012) could not be read in full (publisher pages returned 403), so none of their figures are used. The ISO 3382-3 target values are taken from Lee and Haan’s summary of the standard, not the paywalled standard itself. Gensler’s 2024 and 2025 Global Workplace Survey landing pages did not publish noise-specific percentages. WELL Building Standard sound feature pages returned 404 and are not cited.
Last updated: October 3, 2026. We update this roundup quarterly, and the next refresh is expected when Leesman publishes full-year 2025 noise satisfaction results and Gensler releases its next U.S. Workplace Survey.
