Model for simplified calculation of composite slabs sound insulation characteristics in the presence of impact noi
Journal Title: International Journal of Emerging Technologies in Computational and Applied Sciences - Year 2018, Vol 23, Issue 1
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 12354-2:2017 and professional software INSUL. In the experiments are calculated the impact sound insulation index using composite slab reinforced with profiled steel decking covered with lightweight underfloor heating and the possible improvement with additional damping layer under the underfloor heating. The experimental results presented with tables and graphics show the work of the proposed model and its abilities to be used in practical implementations of composite insulation materials and structures test
