Acoustics: why is it at the heart of workplace performance?

In industrial, tertiary or high-tech environments,acoustics is a key performance factor. Too often perceived as a simple question of comfort, it actually plays a central role in the productivity, safety and durability of equipment.

Whether it’s a noisy production shop, control room or cubicle, poor acoustic management can lead to fatigue, human error, communication problems or regulatory non-compliance. Conversely, well-conducted acoustic engineering improves overall performance, reduces risks and contributes to a better working climate.

SIM Engineering supports manufacturers in meeting these challenges through numerical simulation and finite element modeling services applied toindustrial acoustics and vibration.

SIM Engineering’s acoustic engineering expertise

Complete mastery of industrial and environmental acoustics

Specialized inengineering, SIM Engineering integratesacoustics into its analysis and design approach from the earliest stages of projects. Thanks to an approach combining physical modeling and 3D acoustic simulations, we are able to anticipate the vibratory, sonic and resonant phenomena that impact system operation and conformity.

Our scope of action covers :

• Analysis of acoustic radiation from structures or machines;
• Dealing with noise pollution in industrial environments;
• Vibration optimization of equipment subjected to dynamic loads;
• Sizing passive or active acoustic treatments;

Our simulations take into account the propagation of sound waves in air or materials, reflections, diffractions and absorption, to guarantee a realistic and relevant approach.

Digital simulation methodology and tools

We implement a rigorous four-stage methodology, adapted to the requirements of each customer and in line with current standards (ISO 9613, EN 12354, etc.):

1. Functional and acoustic analysis of the environment (noise sources, propagation paths, target levels) ;
2. 3D modeling using finite elements (FEM) and/or boundary elements (BEM), depending on the frequencies studied;
3. Digital simulation and post-processing (SPL levels, sound mapping, resonance effects, etc.);
4. Suggested technical solutions (screens, absorbing materials, damping, vibration decoupling, isolation, etc.).

We work with the best industrial simulation software, combined with in-house tools developed for specific analyses.

Practical applications of acoustics in industry

Real-life case studies conducted by SIM Engineering

• Aeronautics: sound modelling around turbine test benches, reduction of over 12 dB using screens and absorbers.
• Construction: support during the design phase to comply with noise regulations (NRA).
• Thermal renovation: adjusting solutions to preserve acoustic performance.
• Noisy activities in residential areas: noise impact studies, 3D modeling, recommendations for limiting nuisance.
• Collective interior spaces: acoustic treatments to reduce reverberation and improve intelligibility.
• Industrial projects and events: regulatory impact studies and integration of technical/budgetary constraints.

These interventions demonstrate that acoustics is about more than just comfort: it’s also about operational performance, structural durability and regulatory compliance.

The benefits of an integrated acoustic approach

A triple win: technical, human, economic

• Technical performance: noise reduction, elimination of resonance effects, optimal machine operation.
• Operator well-being: improved concentration, reduced auditory fatigue and stress.
• Compliance and image: compliance with regulatory thresholds, greater acceptability of installations.

By integratingacoustics right from the design stage, rather than correcting them after the fact, our customers optimize their investments and limit adaptation costs. Acoustics thus become a lever for product differentiation, particularly in competitive sectors where perceived sound performance is a determining factor.

Growing challenges in the age of ecological transition

Environmental acoustics is also becoming an issue of social responsibility. Regulations are becoming stricter, and local residents are increasingly sensitive to industrial noise pollution. Anticipating these constraints makes it possible to:

• Avoid costly litigation
• Obtain administrative authorizations more easily
• Reinforce our reputation as a responsible company

Acoustics and occupational health: an underestimated challenge

Noise in the workplace is recognized as a major occupational risk factor. Poor acoustics can lead to hearing problems, mental fatigue, stress and miscommunication. Thanks to precise acoustic models, SIM Engineering offers targeted solutions to reduce noise exposure: partitioning, absorbent materials, spatial reorganization or ergonomic layout.

Standards and regulatory requirements for industrial acoustics

Professional environments are subject to strict acoustic standards (Directive 2003/10/CE, ISO 11690, ISO 9613, Labor Code, ICPE). SIM Engineering supports its customers in bringing their facilities into compliance, through predictive analyses and usable reports. The aim is to ensure the safety of workers and the long-term viability of industrial projects.
