THE EFFECT THICKNESS OF THE PANEL WITH THE APPLICATION OF RUBBER CRUMB AND FREQUENCY RANGE ON THE VALUE OF THE SOUND INSULATION INDEX

Abstract

The article is devoted to the issue of increasing the level of sound insulation in the construction of a wall panel. To solve this problem, an analysis was made of the effect of the frequency and particle size distribution of the mixture on the value of the sound insulation index. It was also shown varying the amount of sound insulation depending on the thickness of the wall panel, which was made using rubber crumb. The methods of production and the range of application in the modern industry of crumb rubber as a material of grinding worn tires, which is one of the most large-capacity polymeric wastes, are considered. The installation structure of sound insulation panels during the experiment is illustrated. The results of determining the level of sound insulation were compared and presented on the diagrams for each group separately.
