To test the effects of masked and unmasked office noise on arousal, stress and cognitive performance, each of three groups of 15 student volunteers was exposed to one of the following conditions: taped office noise (54 dbA with bursts to 60-66 dbA), the same noise masked by white noise at 59 dbA, and no extraneous noise. Findings confirmed predictions based on theories of arousal and disruptive stress. The no noise group performed best on a measure of cognitive complexity and felt the least… 
Performance, fatigue and stress in open-plan offices: the effects of noise and restoration on hearing impaired and normal hearing individuals.
TLDR
The impact of noise and restorative conditions varied with the hearing characteristics of the participants, with impaired performance for tasks that involve recall of semantic information and higher stress hormone levels during the high noise compared to the low noise condition.
Office noise and employee concentration: Identifying causes of disruption and potential improvements
A field study assessed subjective reports of distraction from various office sounds among 88 employees at two sites. In addition, the study examined the amount of exposure the workers had to the
Habituation and dishabituation to speech and office noise
The authors examined whether background noise can be habituated to in the laboratory by using memory for prose tasks in 3 experiments. Experiment 1 showed that background speech can be habituated to
Unmasking the effects of masking on performance: The potential of multiple-voice masking in the office environment.
TLDR
Comparison of broadband noise with two alternatives-multiple voices and water waves-in the context of a serial short-term memory task found a single voice impaired memory in comparison with silence, but when the single voice was masked with multiple voices, performance was on level with silence.
Stress and open-office noise.
TLDR
The simulated open-office noise elevated workers' urinary epinephrine levels, but not their norepinephrine or cortisol levels, and it produced behavioral aftereffects indicative of motivational deficits, but the groups did not differ in perceived stress.
Background music as noise abatement in open‐plan offices: A laboratory study on performance effects and subjective preferences
Continuous noise is played in many open-plan offices to partially mask ambient sounds, in particular background speech. With this, the detrimental impact of background sounds on cognitive performance
The effect of speech and speech intelligibility on task performance
TLDR
Performance in real open-plan offices could be improved by reducing speech intelligibility, e.g. by attenuating speech level and using an appropriate masking environment.
Influence of active-noise-cancelling headphones on cognitive performance and employee satisfaction in open space offices
High speech intelligibility in open space offices leads to problems. As a result of the irrelevant sound effect it influences cognitive performance negatively. Roomacoustic measures do often not lead
