Noise is known to be one of the most common negative factors that can have detrimental effect on human and the environment. In the article the expected noise load on the territory of a residential development located in the immediate vicinity of a metallurgical plant is analyzed. A steel arc furnace is taken as an active source of noise. Account has been taken of the main techno-economic, structural and social indicators of the situation in which housing development has been organized in close proximity to existing industrial plants. All the data obtained from studying the propagation of noise from the source are processed on the basis of the complex mathematical model in the PTC Mathcad Application. The model makes it possible to carry out studies of distribution of the air noise of an active industrial source in multifunctional areas, to carry out calculations in accordance with the established normative methods, and to analyse the CPD over the whole frequency range. It is also possible to analyse the application of the most effective ways of reducing acoustic load. The most effective engineering solution is a complex screening scheme which makes it possible to reduce the sound pressure levels of the frequency range from 20Hz to 10 000Hz by 20-25 dB, thus satisfying the modern requirements of sanitary standards for residential development.
