According to the definition of sustainability, a product can be considered sustainable if its production enables the resources from which it was made to continue to be available for future generations. A sustainable product can thus be created repeatedly without generating negative environmental effects, without causing waste products or pollution, and without compromising the wellbeing of workers or communities. In the last years many new materials for noise control have been studied and developed as alternatives to the traditional ones (glass or rock wool); these materials are either natural (cotton, cellulose, hemp, wool, clay, etc) or recycled (rubber, plastic, carpet, cork, etc.). Various methodologies have been proposed to evaluate the sustainability of materials and products (LCA, Ecoinvent, Ecoprofiles). The paper presents an updated survey of the acoustical properties of sustainable materials and in particular sound absorption coefficient, airborne and impact sound insulation data, as well as an analysis of the procedures to asses the sustainability of these materials.

Abstract
According to the definition of sustainability, a product can be considered sustainable if its production enables the resources from which it was made to continue to be available for future generations. A sustainable product can thus be created repeatedly without generating negative environmental effects, without causing waste products or pollution, and without compromising the wellbeing of workers or communities. In the last years many new materials for noise control have been studied and developed as alternatives to the traditional ones (glass or rock wool); these materials are either natural (cotton, cellulose, hemp, wool, clay, etc) or recycled (rubber, plastic, carpet, cork, etc.). Various methodologies have been proposed to evaluate the sustainability of materials and products (LCA, Ecoinvent, Ecoprofiles). The paper presents an updated survey of the acoustical properties of sustainable materials and in particular sound absorption coefficient, airborne and impact sound insulation data, as well as an analysis of the procedures to asses the sustainability of these materials.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
