Résumé

Researchers of /TS and IRSST decided to synergize again their efforts in order to expand the ICAR laboratory and include a facility dedicated to acoustical materials. Acoustic properties of porous materials such as the normal incidence sound absorption coefficient and the normal incidence sound transmission loss together with several physical intrinsic parameters required as input in the most commonly used associated models (i.e., porosity, airflow resistivity, Young's modulus...) can now be measured in ICAR. This new facility aims at (1) improving the knowledge about the physical phenomena associated with the dissipation of the acoustic energy in porous materials of various microgeometries, (2) developing new materials with dedicated or uncommon acoustical properties (e.g., metamaterial, metacomposite,...) for industrial applications such as hearing protection, building, aeronautic or aerospace and (3) providing the input parameters required in acoustical prediction software dealing with acoustical materials.
