Theoretical and practical problems of creation low noise power facilities

The permanent operation of power facilities (boilers, thermal power plants, transformer substations and other) is the cause of the excess noise of sanitary norms in the surrounding area. The most ener-gy facilities are located in areas close to residential areas. The theoretical and practical aspects of the creation of a low-noise power facility are discussed. It is shown that the creation of a mathematical model of the energy facility allows us to consider the effect of the limiting factors in the creation of low noise object: the number of noise sources, the noise characteristics of the sources, source loca-tion, operation modes of equipment, index of direction, the orientation of the energy facility in rela-tion to the residential area and the other factors. The location of noise sources at a height above the ground level has a significant impact on noise levels in the surrounding area and the possibility of creation of low noise object. For each type of power facilities were marked groups of noise sources and the typical noise reduction measures were shown. Here are considered well-known and original activities to reduce noise. The important point for the creation of a low-noise power facility is a complex application of noise reduction measures.
