Abstract: Calculations of composite slabs sound insulation characteristics is very important not only as theoretical researches, but mainly in practical tests in the effort to choose suitable characteristics of a tested structure, combining different insulation materials and changing their position in the tested structures. The existing methods and appropriate models for calculation of composite slabs sound insulation characteristics are complex and time consuming. Therefore, the goal of this article is propose and investigate a model of simplified calculations of composite slabs sound insulation characteristics to speed the appropriate decision when testing and choosing the suitable composite insulation structures and speed the comparison of the effect of placing different materials, combining them in different structures. As theoretical basis in the development of the proposed model are used fundamental for insulation Cremer's theory, the international standard for insulation EN ISO 12354-2:2
