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...)
