Noise, a silent enemy of productivity
In control rooms, where concentration and communication are essential, acoustics play an often underestimated role.
Yet a poorly controlled noise environment can have deleterious effects on operators' performance and health.
Recent studies show that high noise levels in open spaces can reduce productivity by 66% and increase errors by 50%.
Understanding and mastering the acoustics of an SDC is not an option, but a necessity.
Understanding the fundamentals of acoustics for optimum efficiency
The distinction between sound insulation and sound correction is crucial. While the former is concerned with reducing noise from outside or transmitted to the outside, the latter focuses on hearing comfort within the room itself.
Acoustic correction is a key concern in SDCs, as it limits noise disturbance between operators.
A 2020 study published by INRS shows that work environments where reverberation time exceeds 1.2 seconds are perceived as "stressful" by 72% of employees. It is therefore imperative to optimize this parameter to promote clear communication and reduce hearing fatigue.
Why are acoustics essential in control rooms?
SDCs are specific spaces where collaboration and concentration coexist. Unfortunately, modern materials such as concrete, glass and steel, while aesthetically pleasing, amplify acoustic problems.
According to a 2019 survey by the Acoustic Society of America, over 60% of operators in open supervisory rooms report that noise pollution impacts their ability to concentrate and increases their stress levels. Acoustic management therefore becomes a strategic tool for improving quality of life at work and preventing human error.
What can be done to improve acoustics?
Improving the acoustics of an SDC involves much more than simply installing insulating materials. It calls for a global approach that integrates both a reverberation time (RT) adapted to use and good management of sound sources.
Acoustic ceilings :
Installing a false acoustic ceiling is undoubtedly the most cost-effective solution, provided you use high-performance products.
These absorbent elements, made from rock wool or compressed foam, significantly reduce reverberation time. Their effectiveness has been proven: an average 30% reduction in overall noise levels in rooms treated with acoustic ceilings was measured in 2021.
Wall panels and stretched canvas :
Strategically placed, they absorb sound at its source. A study of collaborative spaces shows that these panels can reduce noise pollution by an average of 25%.
Its solutions can also be used for their decorative potential.
Reducing equipment noise:
By isolating the machines and using appropriate headphones, operators benefit from a calmer, more efficient working environment. Relocating central processing units to a dedicated room is highly effective both for noise control and temperature control.
Methodology: from analysis to results
An effective acoustic optimization project is based on a methodical approach, guided by the expertise of an acoustician.
The first step is to assess the ambient noise level and reverberation time.
A recent study shows that acoustic diagnostics can reduce the cost of work by up to 40% by accurately identifying the interventions required.
Specific recommendations are then implemented, such as treating at least 20% of the room surface with sound-absorbing materials. A post-work inspection ensures that acoustic comfort targets have been met.
Concrete examples of success
The acoustic solutions implemented by SOA in recent projects are proving their effectiveness. For example:
- A89: The installation of a suspended acoustic ceiling reduced reverberation time from 1.5 seconds to less than 0.8 seconds, considerably improving operator comfort.
- SOLVAY: The addition of vegetated panels not only reduced noise pollution, but also created a soothing visual atmosphere, increasing employee satisfaction by 20% according to an internal survey.
Conclusion: acting today for a peaceful future
Controlling acoustics in control rooms is much more than a technical issue. It's a strategic approach that has a direct impact on the quality of working life and team performance. So why wait? Contact SOA for a personalized diagnosis and transform your spaces into exemplary environments.
