A DENORMS special session will be held during the ISMA2018 Noise and Vibration Engineering Conference. The conference is organised by the division PMA of the KU Leuven in Leuven (Belgium) from 17 to 19 September 2018.

Abstracts for this special session can be submitted via the regular procedure of the conference, which can be found on https://www.isma-isaac.be/isma2018/abstract-submission/, but ‘DENORMS’ must be entered in the remarks field to the programme committee.

The deadline of the abstract submission for  special sessions is 15/02/18.

The ISMA2018 Noise and Vibration Engineering Conference is the 2018’s edition of a sequence of biennial international conferences on noise and vibration engineering, structural dynamics and modal testing. Since 2012 the ISMA conference is organized in conjunction with the USD conference on Uncertainty in Structural Dynamics. The 2016 edition of ISMA/USD conference was attended by more than 600 participants from academia and industry. The technical programme counted approximately 450 technical papers scheduled into 8 parallel tracks and 4 plenary poster sessions. Full conference proceedings will be published digitally and submitted for reference in the ISI Web of Science. A single registration will grant access to both the ISMA and the USD conference.

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 “Sandpit: New approaches to design of noise reducing materials and structures”

DENORMS Action’s Brainstorming Workshop “Sandpit: New approaches to design of noise reducing materials and structures”, took place on 14th and 15th September 2017 in Novi Sad (Serbia), organised by University of Novi Sad.

The goal of this sandpit was to develop new ideas and collaboration plans on the following topics:

  • Sound absorption by structured materials
  • Diffusers and metasurfaces
  • Sound insulation by structured materials
  • Landscape sound insulation by sonic crystals
  • Active structures and smart materials
  • Elastic energy mitigation
  • Vibroacoustic energy mitigation in thin walled structures
  • Characterisation of non-conventional porous materials and acoustic metamaterials

This sandpit was a timely and unique opportunity to achieve scientific breakthroughs in the identified topics and to enhance collaboration between the DENORMS members. To achieve this, brainstorming groups composed of 4-5 people from the 3 Action Working Groups worked together for 1 ½ days in a positive collaborative environment. Each brainstorming group nominated an Animator, in charge of leading the discussion and of reporting its outcomes. The expected outcomes for each group were: new concepts and approaches, detailed work plan including a tentative schedule of joint grants applications, publications and STSM). They were reported and discussed during the feedback session in the afternoon of 15th Sept. 2017 (½ day). For more information, see the Flyer.

The pictures of the Workshop are available here.

DENORMS – GDR Meta thematic day « Industrial applications of acoustic metamaterials »

DENORMS Action and the GdR META organised in Marseille on 1st September 2017 a thematic day dedicated to Industrial applications of acoustic metamaterials. This event aimed at gathering industrial and academic partners to discuss and exchange views. It was structured around presentations given by leading industrial partners in various fields of applications. The talks introduced current issues, new trends or metamaterial-based solutions already implemented in a practical context. Coffee breaks, poster sessions and panel discussions took place throughout the day in order to foster informal exchanges among the participants. This thematic day was organised as a side event of the Metamaterials 2017 Congress, allowing the participants to combine an industrial and practical perspective on acoustic metamaterials with an overview of the state-of-the art of the domain.

Participation was open to all, students, researchers, engineers or technical staff from academia or industry.

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
