Analytical Calculation of Vehicles Noise in the Road Traffic and Graphical Presentation

Noise in general is considered a concern of society, because it creates various obstacles during the time of work and holidays especially at night. Also high level of noise is considered as a significant pollutant of the environment. Therefore, it is of practical importance to derive a mathematical expression for the calculation of noise level. In this paper are given the mathematical expressions for calculation the level of noise caused by road traffic. By the program which is created in MathCad are obtained results, tables and diagrams of the noise level when the road vehicles are travelling and the influence of various factors in noise generation and propagation.
