The paper presents an attempt to unify the issue of acoustic vibro-insulation used in the design of buildings and its impact on the building structure based on a calculation example. While the methodology of selection and methods of acoustic insulation of buildings from airborne traffic noise, as well as methods of limiting the structure vibrations to acceptable levels are widely recognised and applied, there is no generally accepted methodology of limiting the secondary noise that can be generated in buildings as a result of vibrations transmitted through the ground to the foundations and structure of the building (so-called ground-borne noise or re-radiated noise).

Solution of the problem of limiting the spread of the dynamic and acoustic emissions from rail and road traffic requires application of new elastomeric materials are characterized by both high acoustic insulation as well as being part of vibroisolation system between the source of vibration associated with the movement of vehicles and construction engineering structure. In the new solutions of vibro-and soundproof , isolation based on the new elastomer materials should be taken into account a strong correlation between physico-mechanical properties of these material and the values of static and dynamic load, which effect on these materials. Another problem, which is associated with the use of elastomer materials, is the influence of the volume of used item on their physico-mechanical parameters. Therefore, the use of elastomer materials in vibro-and soundproof isolation systems requires at the stage of selecting of materials a number of studies that will allows specifying the properties of materials for a specific application. A properly conducted process of selection of materials will help to achieve the desired effect, which is to build a well-functioning vibro-and soundproof isolation system. Without a properly conducted process of selection of materials can be achieved counterproductive result. In the paper, the results of experimental studies carried out to determine the physicomechanical elastomer material that could be used as a flexible bearing in structural engineering constructions are presented. Flexible nodes bearing can be classified as the latest generation of vibroisolation systems. The studies were also performed to assess the possibility of using such materials in soundproof isolation in concert halls and conference rooms. In the paper, the new methodology of assessment of physico-mechanical elastomer materials that could be a standard for the design of vibro-and soundproof isolation systems and based on such materials in the newly designed civil engineering structures.
