STRESZCZENIE
In modern conditions of urban areas development, the importance of protection against noise is increasing. Measures to reduce noise levels in the city's districts should be comprehensive and combine both organizational and architectural-construction and engineering-technological measures. To determine the most optimal combination of countermeasures, it is necessary to initially identify the sources of noise, determine their features and parameters. A complete basis for development of a set of noise reduction methods and means can be mapping of noise levels, which visually allows to determine the intensity and direction of sound spreading. One of the districts of Zhytomyr, which is isolated from other parts of the city and is characterized by a developed infrastructure and heavy traffic, was chosen for noise measurements. Measurements were performed in areas characterized by uniformity of placement, coverage of all functional areas and ability to measure the noise level both at the source of its formation and within the residential area. Based on statistical processing of the experimental data cartographic models of spatial spread of noise pollution are developed. According to the results of the research, zones with different levels of noise pollution were identified. The created map allows to choose the most optimal measures to reduce noise exposure, taking into account the characteristics of each residential area. The design noise level was determined taking into account the measures and noise map was created. The estimated efficiency of the developed measures allows to reduce the total noise level inside the district by 7-8 dB.
