Recent projects
Some of our recent projects are:
- Design of multi-fonctional materials (with mainly acoustical and thermal capabilities).
- Investigation of the potential of heterogeneous porous material for the reduction of enclosed machinery noise.
- Optimisation of pore sizes, distribution and shape of mineral foams.
- Increase of acoustic properties of heterogeneous porous materials based on recycled matters.
- Sound absorption preditions and measurements in impedance tube on large anechoic wedge samples (cross-section: 600 x 600 mm2, thickness up to 1 500 mm) used in anechoic rooms.
- sound absorption measurements, characterizations and modeling of systems composed of perforated plates and porous materials for building applications.
- Interpretation of physical phenomena involved in the danping of concrete floors.
