Using different waste as resilient layers for impact sound insulation improvement: New alternative to commercial layers?

In the residential building sector, the use of floating floors is a common practice which increasingly used to reduce vibrations and impact noise. These are usually made from industrial materials, although the emerging concern for sustainable construction is leading to the use of other materials from recycled waste. This article studies the performance of rubber, cork, and cigarette butts as a floating floor. For this purpose, their acoustic properties (ISO 9052-1 and 12,354-2 standards) are analyzed and compared with those of some commercial materials. The results obtained indicated that the performance of these eco-materials is equal or superior to that of commercially available materials.
