Abstract
Moreover noise levels in work and home surroundings is away to index the human comfort , that’s why the increasing attention is devoted to investigate noise processes. Such a process is considered to be harmful consequences of transport usage and the noise generated by transport vehicles, its distribution and its variation in the internal transport vehicles’ spaces and various noise sources in particular. Engineering, organizational and administrative noise reducing measures are also reviewed together with noise effects that are considered harmful to human health. Traffic velocities increase as the railway transport rolling stocks improve technically and become more perfect and sophisticated, the noise they generate is intensified too and noise limits are exceeded. Several major factors are considered here: the condition of rail and wheels, the type of trains as well as the question of the specific prediction method used. 2D and 3D locomotive models were used for solving this important problem. In this investigation the results and the comparison of given simulation are presented.
