Assessment of the Acoustic Efficiency of Noise Protection Screens on the Roads of the City of Irkutsk

Abstract

The aim of the study was to assess the effectiveness of noise protection structures on road sections in the city of Irkutsk (Irkutsk region). Methods. With the help of sound level meters, instrumental measurements of the sound pressure level were carried out in the territories equipped with noise shields. Results. The analysis of the results obtained and their comparison with the established sanitary standards for their excess is carried out. The calculation of the statistical characteristics of the noise level has been carried out. The analysis of the data obtained as a result of the measurements made it possible to draw conclusions about the insufficient efficiency of the structures that reduce the noise level only at a distance of 1 and 10 m from noise sources and do not allow bringing the noise level to the established sanitary standard (55 dBA). Conclusion. In the considered territories, it is necessary to take measures to protect the population from road traffic noise.
