Example of material samples tested

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

Matelys - Acoustique & Vibrations is a young consulting company, created in december 2005, whose members emanate from the acoustic laboratory staff of ENTPE.

Matelys-AcV main specialities 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 for the vibro-acoustic behavior prediction 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 and building acoustics.

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...)
