Phononix Gabions

Phononix Gabions are based on the metamaterial’s technology, which is characterized by the following properties:

  • acoustic labyrinth: sound absorption guaranteed by the air path and the functionalized perforations;
  • sound absorption tunable at different frequencies;
  • circular economy approach (Alufoil + honeycomb);
  • porous or fibrous materials are not needed.

The sound absorption and insulation performances are based on the following two metamaterials mechanisms:

  • vibrating membrane, related to the resonance of the honeycomb surface;
  • functionalized surface, related to the energy dissipation due to surface microperforation.
