The problem of vibration and sound insulation in transport issues

This paper addresses issues that are currently quite often, both in scientific studies and in journalism (the press), deliberately or due to a lack of sufficient knowledge, poorly framed. It is finally necessary to explain what vibration insulation is and what sound insulation is, and how one concept differs from the other, especially since in many cases materials whose physical and mechanical properties determine their use for sound insulation are used as vibration insulation elements. The differences between vibration insulation and sound insulation are significant and worth explaining, particularly in the context of road and rail transport routes, which is the subject of this article. The results of the work are the result of research carried out under research project 4875/B/TO2/2010/38.Vibration insulation and sound insulation are separate issues from a practical point of view.
