Stone masonry walls: Insights in prediction of structural transmission loss in non-homogeneous and anisotropic partitions

To preserve the historical stone masonry buildings and the local landscape, for both newly developed buildings and renovation of existing buildings, natural stone masonry is a priority resource for reconstruction or renovation, in particular in areas recently devastated by seismic events. Since residential buildings must guarantee adequate comfort for inhabitants, based on well-defined technical performances, the transmission loss of vertical partitions in stone masonry building, typical of the Mediterranean area, as well as typical of the Alps and Apennine mountain areas, is evaluated, according to seismic safety criteria. From an acoustic point of view, the reduction of sound transmissions through stone masonry walls mainly depends on the mass, but also on the inhomogeneity of the structures, which reduce the transmission of vibrations.
