YOUR CUSTOM STUDY

Our approach adapts to the maturity level of your project to provide the most relevant technical solutions. Analysis, simulation, design, validation: each step is tailored to precisely meet the identified need.

SUBMIT A REQUEST

Simulate and experiment to test an idea or concept against the results and decide how to proceed with the project: continue, adjust, or stop.

Understand the problem, identify the key factors, define performance indicators, and evaluate technical scenarios.

Develop a suitable architecture: optimized processing, custom metamaterials, quarter-wave resonators, or specific geometries.

OUR FIVE-STEP PROCESS

UNDERSTAND
Identify the need; analyze the environment, sources, transmission routes, and usage constraints.
DESIGN
Formulate hypotheses, explore architectures, and select the parameters that actually influence performance.
Laboratory
TEST
Combine simulation, prototyping, and testing to compare scenarios based on measurable criteria.
Products
INTEGRATE
Tailor the solution to the geometry, materials, process, and usage constraints.
Products
VALORIZE
Document the results, transfer knowledge, and support the transition to a reproducible or marketable solution.

OUR MEANS

Numerical simulation

Metacoustic uses the finite element method to model acoustics, vibrations, and their interactions with other physical phenomena.



We rely on COMSOL Multiphysics and develop our own numerical tools tailored to the specific challenges of our projects. This approach allows us to analyze a system’s behavior, identify key parameters, and compare different configurations before moving on to prototyping.

Prototyping, measurement, validation

While simulation speeds up the design process, measurement remains the gold standard. Whether in the early stages to feed data into our digital models or in the final phase to validate a prototype, we conduct your tests at our test center or on-site.

Acoustic and Vibration Characterization

  • Sound insulation (under normal incidence or in a diffuse field)

  • Absorption Performance (characterization in normal incidence or diffuse field)

  • Sound power radiated by the structures

  • Vibration Analysis and dynamic behavior

Providing actionable results

  • Acoustic insulation indicators: STL, Rw, Ra,tr
  • Acoustic absorption indicators: αw, ALPHA, classe d’absorption
  • Psychoacoustic indicators: Perceived quality, RASTI, ...
  • Eco-conception indicators: Mass reduction, CO2, fine particules, ...
 

AREAS OF PRACTICE

Acoustic insulation

Minimize sound transmission through walls and building envelopes.

Acoustic absorption

Reduce reverberation and sound energy at specific frequencies.

Vibro-acoustic

Analyze vibrations and their coupling with sound radiation.

Noise under flow

Reduce flow noise in ducts, vents, and equipment.

Quality & Perception

Optimize the frequency spectrum and sound signature to improve perception.
