Metacoustic launches Metablocker, a metamaterial that revolutionizes acoustic insulation

Twice as light as traditional solutions, the Metablocker offers optimal sound insulation. This innovation promises to transform the building, transportation, industrial, and household appliance sectors, addressing the challenges of comfort, public health, and ecological transition.

Noise: a public health and economic issue

Noise is now recognized as an invisible form of pollution with major consequences. Sleep disorders, stress, cardiovascular diseases: proven impacts on health; decreased productivity and property depreciation: considerable economic and social costs. We are currently talking about an annual social cost of noise in France of €147 billion. (source: ADEME, 2021).

According to Clément LAGARRIGUE, CEO and co-founder of METACOUSTIC: "Noise is a silent scourge, but its effects are very real. It is urgent to act to protect the health of citizens and improve our living environment."

The Metablocker: a technological breakthrough for lightweight and effective sound insulation

The result of 10 years of R&D, the Metablocker is a composite metamaterial designed by METACOUSTIC to offer unparalleled acoustic performance, while halving the weight of traditional materials.

Its key assets:

• Lightweight: 5 kg/m² for insulation equivalent to a 10 kg/m² material.
• Versatile: applicable in building construction, transport (rail, aeronautical, naval), industry and household appliances.
• Environmentally friendly: reduced carbon footprint thanks to its lighter weight.
• Innovative: patented and successfully tested with partners such as Naval Group, SNCF and Chantiers de l'Atlantique.

For Clément LAGARRIGUE: "The Metablocker makes it possible to combine acoustic performance, lightness and durability. It is a key solution for sectors where weight and efficiency are critical."

A commercial rollout phase in 2026

METACOUSTIC is preparing to launch the Metablocker in 2026. The company is aiming for Euroclass (building) and sector (railway, aeronautical) certifications, and is engaging in discussions with distributors and specifiers (acoustic design offices) to accelerate its adoption.

For Clément LAGARRIGUE: “We are ready to scale up to industrial production. Our goal is to make the Metablocker accessible to all sectors facing noise pollution.”

METACOUSTIC, a committed player for a sustainable sound environment

Beyond its innovation, Metacoustic is committed to:

• Raising awareness among the general public and industry about the issues surrounding noise.
• Supporting the ecological transition through lightweight and sustainable acoustic solutions.
• Collaborating with public and private stakeholders to reduce the noise footprint of our societies by offering outsourced R&D services.

For Clément LAGARRIGUE: "We believe in responsible acoustics, serving both well-being and the planet."
