In the modern conditions of society development the role of protective plantings is great importance. In particular, types of such plantations in the study are protective strips along the roads. At first glance, it is difficult to trace the processes that take place in these lanes. However, by selecting the appropriate adapted research methodology, it is possible to trace these seemingly hidden functions. The significance and relevance the use of roadside forest strips in the context of their noise-absorbing functions are presented. Attention is paid to the analysis of noise load for the operation of large vehicles on highways of international and national importance in the conditions of Western Polissya. An analysis of recent scientific publications with an emphasis on protective plantings as an effective means of preventing negative acoustic loads. The main purpose of the research was to determine the noise-absorbing properties of roadside forest belts depending on their design features and species composition. It is noted that the solution of program tasks of work is carried out with the use of special techniques of researches of noise-absorbing effect by protective forest plantations on transport ways. The comparative characteristic of noise-absorbing effect roadside forest strips and noise-protective screens are executed. On the basis of the conducted researches the mathematical models describing a decrease in noise level depending on a design of roadside forest strips are developed. The generalization of the experimental results showed that the roadside strips of dense and openwork structures are marked by the highest quality noise-absorbing effect. Noise protection screens in the study area help to reduce the noise level to 60 dB and less, it than ensure compliance with the necessary sanitary standards for settlements.
