 Project objective

Sound pollution is an omni-present problem in our modern society that affects our well-being and the quality of life. Technical solutions to reduce the impact of sound in a broad frequency range are therefore of vital importance. Moreover, solutions should be economically attractive, since the volumes of sound insulation required in our society are extremely large. Acoustic foams are nowadays one of the best available solution towards this problem, but they are mainly effective in the mid- and high-frequency regime. Novel technical solutions that target the lower frequency regime are therefore urgently needed. Within the ERC-AdG project MECHMAM, a possible solution has been proposed in the research on dynamical metamaterials. One particular category proposed in that ERC-project are acoustic metafoams. This novel class of materials are enriched acoustic foams, whereby a mass is implemented in the cavities of the foams. This combines two effective mechanisms, i.e. visco-thermal dissipation and local resonance. Interestingly, the project showed on a model-basis that the interaction between these two operating mechanisms may lead to an amplification of the damping within the material, leading to a potentially very efficient sound insulator. Within the ERC-AdG-project, most findings were still theoretical or model-based. This PoC-project aims to assess this basic idea and bring it to practice. In order to reach this objective, attention will be given to the metafoam manufacturing methods having potential for large volume production and the validation of the metafoam actual performance. Parallel to the technical activities, a competitive market analysis will be carried out to establish the IPR and the commercialization plan, in collaboration with industrial and societal partners. We will further explore technology transfer towards various end-users. Market outreach will be performed so that the metafoam products and services reach their potential customers.

Are you the coordinator (or a participant) of this project? Plaese send me more information about the "METAFOAM" project.

For instance: the website url (it has not provided by EU-opendata yet), the logo, a more detailed description of the project (in plain text as a rtf file or a word file), some pictures (as picture files, not embedded into any word file), twitter account, linkedin page, etc.

Send me an  email ( and I put them in your project's page as son as possible.

Thanks. And then put a link of this page into your project's website.
