4th Seminar Acoustics and Industry “Development and certification of building materials and systems”,
Ferrara and online 16 September 2022

The fourth Seminar on Acoustics and Industry, the first edition of which dates back to 2014, aims to constitute not only a moment of technical-scientific updating for designers and researchers, but also a fruitful space for interaction between the vast world of acoustics and the industrial one. The theme of this edition concerns building materials, as there are numerous innovations in this sector both in the field of certification and the development of new materials.
As regards the certification of materials and building systems, there are numerous standards that have come out in recent years or are under discussion in national and international technical committees; it is therefore appropriate to take a comprehensive look at the regulatory situation, to highlight the changes that are expected in this field.
In the field of the development of new materials, great impetus has taken place in recent years in the meta-materials sector, also favored by the widespread diffusion of three-dimensional printing techniques that allow rapid prototyping of even very complex objects. These meta-materials are being studied by numerous Italian research groups and can be used in various industrial sectors, from aeronautics to automotive, up to the industrial sector and construction.
Alongside these materials, there is increasing interest in the development of sustainable acoustic materials, such as sound-absorbing materials obtained from recycled or natural fibers. The afternoon session aims to illustrate the state of the art of research in this field and encourage the exchange of ideas with technicians and manufacturers for a future application of these materials.
