« Industrial days on new acoustic treatments, acoustic metamaterials and sonic crystals »
The sixth workshop « Industrial Days on New Acoustic Treatments, Metamaterials and Sonic Crystals” organised by COST Action DENORMS took place from February 28th to March 1st in Athens, Greece.
The objective of the workshop was to facilitate dialogue and establish new collaborations between industry and academia on the topics of new acoustical materials / metamaterials. 10 companies and 8 university research groups participated in the event. The program included presentations, group work and social activities.
Each participating company had the opportunity to present its unique development capacities, products and processes (20 min + 5 min of questions) and was encouraged to propose an informal discussion topic.
COST Action DENORMS provided 30 grants covering the costs of meals and accommodation for participants in Athens.
The following companies participated in the Workshop:
- St Gobain
- Trèves Group
- Carbon Air
- Acoustic Metamaterials Group
- Safran Group
The agenda is available here.
