A large amount of regulatory and technical documentation, from state standards to guidelines governing the requirements for noise barrier design and location, has been currently developed in Russia. However, despite such an abundance of regulatory and technical documentation, it is extremely difficult to achieve compliance between the theoretical and practical noise barrier efficiency. According to the study, in the 3rd year of operation, 7 out of 10 noise barriers have already lost their original acoustic properties, the state of 50% of the NB can be estimated as ‘moderate’, 20% - as ‘bad’. Starting from the 8th year of operation, the condition of 50% of the NB is characterized as ‘moderate’, and 50% - as ‘bad’. It is necessary to adjust the regulatory and technical documentation taking into account the main issues and errors encountered in practice.
