THE COMBINED METHOD OF CALCULATION OF NOISE CONDITIONS IN INDUSTRIAL BUILDINGS OF THERMAL POWER STATIONS

Problem statement. Power objects (heat and power plants, district heat plants, and boiler plants)are located within the precincts of the settlements and are sources of elevated noise levels. Thereuponthere is a necessity of estimation of a noise conditions in the premises of thermal power stationsand in the territories adjoining to them. The process of formation of noise conditions in thethermal power station premises is a difficult multiple process, which requires sophisticated mathematicalmodels for its description. The existing methods do not provide obligatory accuracy ofcalculations. The development of the new methods is required.Results. The new combined method of noise calculation in industrial premises of the thermalpower stations is proposed. The method is based on the principles of division of glassy and diffusivecomponents of the reflected energy and their calculation, accordingly, with the help of a methodof tracing and a statistical energy method. The total condensation of sound energy in imputedpoints is determined by the power summation of all the components. For the method implementationa computer model is elaborated.Conclusions. The method proposed and the computer model of its implementation provide the solutionof problems of noise estimation in the premises of the thermal power stations and in the adjoiningareas. The accuracy of the calculations is sufficient for an objective estimation of noise andfor development of the measures on its reduction.
