The ecological situation of modern megacities is significantly influenced by the large energy objects – combined heat and power plants, district heating stations, various types of boiler houses. With their, as a rule, around-the-clock work, there is a significant noise disturbance of the urban area adjacent to the energy facilities, including residential buildings. Protection of residential buildings from the noise of gas-air systems (HWS) of urban energy facilities is a complex scientific and technical problem. In the article, this problem is considered on the example of noise impact of gas-air systems of large combined heat and power plants (CHP) on residential areas of Moscow. The generalized scheme of hot water supply, the design parameters of their elements and the characteristics of the main sources of noise are considered. It is shown that it is difficult to determine the energy characteristics of the noise emitted by the HWS, and the necessity of performing accurate acoustic calculations in the development of noise protection equipment from the point of view of acoustics and economics is substantiated. Based on the analysis of existing methods for calculating noise in large-sized channels, a statistical energy method has been proposed for calculating the energy characteristics of sound fields, which makes it possible to objectively estimate the distribution of sound energy in the DHW channels. A program has been developed for its implementation on a computer. The proposed method of calculation and a computer program ensure the accuracy of calculations of sound pressure levels at the exit from the mouths of channels and ventilation grilles.
