Comparison of methods for calculating the propagation of railway transport noise in various types of building
Due to the fact that railways often pass through settlements, both large cities and small rural settlements, many people are exposed to the negative effects of noise. In the existing calculation methods, the process of noise attenuation in building is described in insufficient detail and does not take into account various types of buildings. The paper compares noise reduction calculations according to the methods of GOST 31295.2-2005, SP 276.1325800.2016 and using various software tools with the results of the experiment. Residential buildings of various types, urban and rural, are considered as examples. Based on the calculations obtained, a conclusion was made about the accuracy of the calculation methods and the possibility of their application to correctly determine the noise reduction due to diffraction in an array of residential buildings.
