Prior to the pandemic 70% of office-based employees worked in open-plan offices. Employee complaints about this design are rife. Yet there is little experimental research investigating the effects of office noise on things like cognitive performance, physiological stress, and mood.

We’ve found a significant causal relationship between open-plan office noise and physiological stress. Our results show such noise heightens negative mood by 25%—and these results come from testing participants in a simulated open-plan office for just eight minutes at a time. In a real office, where workers are exposed to noise continuously during the day, we would expect the effects on stress and mood to be even greater…”
