Аннотация

In civil buildings, double enclosing structures with layered elements are widely used as internal partitions. Partitions, having a small surface density, significantly reduce the load on the building’s supporting structures. Such structures are built in a short time and, consequently, construction costs are reduced. To comply with the regulatory requirements for sound insulation in partitions of this type, the number of layers of sheet sheeting is increased and the interior space is filled with sound-absorbing material. This significantly increases the thickness and surface density of the fence. The analysis of the currently proposed lightweight fences and the assessment of their acoustic efficiency show the possibility of improving their sound-insulating qualities by improving design solutions, and in particular, by using layered elements with vibration absorption in the structures of double fences. The acoustic efficiency of such structures increases due to internal losses in the layered elements. The paper presents the results of experimental studies of sound insulation of double fences made of layered elements with vibration absorption, made in large reverberation rooms of Vologda State University, and analyzes the influence of dynamic characteristics of vibration-absorbing materials on their sound insulation. It has been established that for the rational design of double soundproof structures made of layered elements, it is necessary to have a mechanism for regulating the characteristics of vibration-absorbing layers. This will make it possible to obtain effective soundproof structures and develop fences with specified parameters at the design stage.
