Workshop 3 on « Dedicated manufacturing and experimental techniques for acoustic metamaterials and acoustic treatments »

DENORMS Action’s third Workshop on “Dedicated manufacturing and experimental techniques for acoustic metamaterials and acoustic treatments” was held from 5th to 7th February 2018 in Leuven (Belgium), co-organised by KU Leuven and Siemens Industry Software NV.

In this occasion, leading experts shared their knowledge with other researchers, PhD students, young scientists and engineers from all across Europe. Three sessions, each introduced by a plenary lecture, were proposed:

  • Psychoacoustics of metamaterials and acoustic treatments
  • Experimental techniques for testing metamaterials and vibro-acoustic treatments
  • Manufacturing techniques for acoustic and mechanical metamaterials

Three Working Group meeting were held in the framework of the Workshop.

Training School 3 on « Experimental techniques for acoustic porous materials and metamaterials » – Lectures and pictures

DENORMS Action Training School 3 « Experimental techniques for acoustic porous materials and metamaterials » was held from 4th to 6th December 2017 in Le Mans (FR).

This Training School, co-organised by LAUM, UMR CNRS 6613, and DENORMS, aimed at providing a common experimental background to researchers, engineers and technicians working on acoustic metamaterials, metasurfaces and sonic crystals as well as conventional acoustic materials. The Training School covered the following topics:
– Impedance tube measurements
– Ultrasonic characterisation of porous materials
– Mechanical characterisation of porous materials
– Characterisation of sonic crystal
– Characterisation of acoustic metamaterials
– Introduction to psychoacoustics & psychoacoustic tests
– Norms and Standard
– Photoacoustic characterisation at microstructure level

Workshop on “Modelling of high performance acoustic structures Porous media, metamaterials and sonic crystals”

DENORMS Action’s first Workshop on “Modelling of high performance acoustic structures Porous media, metamaterials and sonic crystals” took place on 24th and 25th January 2017 in Rome, organised by Roma Tre University gathering more than 80 participants.

This Workshop was dedicated to theoretical and numerical modelling of acoustic treatments made of porous materials and periodic structures. The Workshop also had a session on Multiphysics applications including electromagnetics aimed at broadening the scope of theoretical and numerical results available in different areas of Physics and Mathematics. On this occasion, the leading experts in these fields shared their knowledge with other researchers, PhD students, young scientists and engineers from all across Europe.

The « Workshop Best Paper » was awarded to Ms. Camille Gaulon, PhD candidate at Laboratoire Matière et Systèmes Complexes, Université Paris Diderot, for her presentation on Acoustic properties and dissipation in liquid foams

 The Workshop was organised in 4 sessions of half a day each:

  • New trends in traditional noise treatments – porous materials and microperforated plates
  • Acoustic metamaterials (i.e. subwavelength absorbers), metasurfaces and sonic crystals for audible sound manipulation
  • New trends in vibroacoustics (i.e. elastic metamaterials and metasurfaces)
  • Use of metamaterials in other fields of Physics and metamaterials exposed to multiple physical phenomena
