Matelys-AcV main competences are:

• the acoustic and elastic characterizations of porous materials,
• the modelling of macro- and micro-perforated acoustic material,
• the modelling of multi-layered poro-visco-elastic materials,
• the microstructure optimisation of acoustical porous media,
• the optimisation of heterogeneous porous media.

From its experience gained at manipulating a large bench of standard and innovative materials, Matelys-AcV designs and implements tools to predict the vibro-acoustic behavior of porous media.

From its knowledge concerning the vibro-acoustic behaviour of poro-elastic materials, Matelys-AcV carries out engineering studies in the domain of transportation, building acoustics, machineries and domestic equipment.

Finally, Matelys-AcV sets up specific, on-demand educational programs on acoustics and vibrations (sound absorption or insulation, outdoor and indoor sound propagation, measurement techniques of acoustic or elastic parameters for porous media...)

Examples of material samples tested and characterized by Matelys-AcV: polymer or metal foams, mineral or glass wools, felts, hollow spheres, screens...
