Noise has become an invisible yet formidable enemy in modern workplaces. In open-plan offices, overlapping conversations, phone calls and the clatter of keyboards directly disrupt our ability to concentrate.
Scientific research is clear: this noise pollution affects our essential cognitive functions, such as working memory, sustained attention and decision-making. In light of these findings, the soundproof booth stands out as a practical, scientifically validated solution for restoring an environment conducive to concentration.
The effects of ambient noise on cognition
Distraction and loss of concentration
Several studies show that ambient noise, even at low levels, reduces cognitive performance. A key indicator, the Speech Transmission Index (STI), shows that a level between 0.7 and 0.9 can lead to an average 7% drop in performance.
Furthermore, a background noise level of around 60 dB(A), common in open-plan offices, directly affects working memory and the quality of performance when carrying out complex mental tasks.
Increased mental load
Reverberant spaces – where sounds linger – require extra effort to speak clearly. The result: a significant increase in cognitive load, a source of mental fatigue.
In the long term, this constant exposure to noise can lead to stress, increased irritability and mental overload, undermining productivity and mental health.
Disrupted cognitive processes
The Irrelevant Speech Effect
One of the main sources of cognitive distraction is exposure to audible but irrelevant conversations. This well-documented phenomenon drastically reduces concentration, especially when two speakers talk at the same time, increasing distraction by 24%.
Cognitive fatigue
As attention is required to ignore background noise, alertness declines. This attentional stress leads to cognitive fatigue, which impairs the quality of work over time.
The benefits of soundproof booths validated by science
A measurable reduction in noise
Soundproof booths are designed to absorb the frequencies of human speech and block out external disturbances. The result: an immediate reduction in auditory distraction, making it easier to concentrate.
According to a study by Mirplay, users report a higher level of concentration and a significant reduction in interruptions.
A positive impact on well-being
Far from being mere bubbles of silence, the booths also contribute to psychological well-being. A survey conducted by Framery shows that 41% of users feel more relaxed after using a booth.
Solutions such as those from Essentielle add an environmental dimension, offering eco-designed booths that improve productivity whilst being sustainable.
How to choose the right acoustic booth
Overall comfort should not be overlooked
For an optimal user experience, it is essential to consider:
- high-flow ventilation, which is quiet and adjustable,
- natural LED lighting,
- ergonomic seating, designed for long sessions.
Adapting to the right use
Depending on the need – phone calls, video conferences, tasks requiring intense concentration – the booth format (1 or 2 people) and its integration options must be carefully chosen.
Technical focus: the Essentielle acoustic booth
Designed to combine performance, comfort and design, the Essentielle booth is based on cutting-edge technology:
- High-density acoustic foam, Silence glazing, soundproof seals,
- Silent ventilation up to 750 m³/h,
- Ergonomic design with integrated connections,
- Customisable options: lighting, furniture, configuration.
It is aimed at businesses seeking a tangible tool to improve concentration and well-being in open-plan offices.
Conclusion
The scientific literature is clear: noise seriously impairs our cognitive abilities. The acoustic pod is not a gadget, but a scientifically validated solution to preserve focus, efficiency and peace of mind.
