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.

Certifications:
