Acoustic Simulation

Analytical and numerical modeling of materials, prototypes and products enables us to improve our understanding of how they function and perform, and to optimize them numerically to best meet your specifications.

Numerical simulation is an excellent way of reducing the time and cost of developing solutions by cutting out prototyping and experimental characterization.

Analytical modelling for dimensioning rules and rapid optimisation, numerical modelling for complex systems

Analytical modelling makes it possible to derive dimensioning rules in the form of equations, which are often simple and therefore easy to interpret. The equations make physical sense. It is also generally well suited to optimizing solutions, thanks to its low computation time. However, it is limited to systems whose geometry is relatively simple or has little physical impact.

Digital modelling - via COMSOL Multiphysics® - of systems makes it possible to work on systems with complex geometry or involving a coupling of physical phenomena. The precision of digital simulations means that we can now talk about a system's digital twin. This greatly accelerates optimization and reduces the need for prototyping and measurement campaigns.

Modelling of materials, prototypes and products

Since materials are the basis of products, understanding their behavior and being able to model them is essential. Acoustic materials such as porous materials, micro-perforated sheets and resonators can be modelled using analytical models with controlled precision. One example is the Johson-Champoux-Allard-Lafarge (JCAL) model for porous materials.

Prototypes are a key stage in solution development projects. They are increasingly produced using 3D printing for reasons of availability, speed and cost. The behavior of 3D-printed acoustic materials is affected by the superposition of layers. Our ability to accurately predict the acoustic behavior of 3D printed solutions - particularly porous materials - means that we can simulate 3D printed prototypes with a high degree of reliability. This avoids questions about the difference in performance between simulations that do not take into account the impact of the manufacturing process and prototypes.

Finally, the products are the industrialized embodiment of the solutions. Modelling helps to guide the choice between different materials, assembly techniques, the impact of gaps, etc. It also helps to avoid unpleasant surprises in acoustic performance when moving from a prototype to an industrialized finished product.
