Using of Recycled Materials to Protect the Working and Natural Environment by Reducing Noise and Vibration

The aim of the article is to define the conditions for the use of recycled resilient materials in the reduction of noise and vibration as an integral part of the mounting and installation of mechanical systems in the work and natural environment. Based on the frequency spectrum, the vibro-isolation efficiency of the vibro-isolators and the viscoelastic materials used is analysed. The solution of this problem is based on the theoretical knowledge and methodology of the transmission of vibration-sound waves. The measurements of the vibration at the sources and along the path of transmission were performed for different recycled materials to compare experimental results with theory.
