DESIGN SOLUTIONS FOR NOISE PROTECTION OF THE POPULATION
Description
The article is devoted to the solution of actual problems of protection of the population from noise production facilities. It shows the various fundamental technological approaches to the implementation of noise protection measures. This work conducts a comparative assessment of technical solutions aimed at reducing the levels of radiated noise, providing increased noise impact on the territory, from the gas distribution station (GDS). Production facilities everywhere are equipped with noisy equipment. If the noise level from the object in a residential area exceeds the permissible levels (RC), they sound events. The most common design decisions noise protection for today are: sound design; noise screens and barriers; insulating housings; sound cab. The article discusses the insulating properties of different coatings, composition and device of acoustic screens. It describes the course of the design work noise-reducing measures aimed at reducing noise levels in a residential area adjacent to the territory of one of the gas distribution stations (GDS). The description of the algorithm calculations, selection of materials for the implementation of activities, the combination of technical solutions that have practical novelty. The article is an exploratory in nature. At each stage of the embodiment of the design decisions were changes in the level of noise and the sound spectrum in the frequency range of 31.5 to 8000 Hz, evaluation of the effectiveness of the protective measures and the analysis of the influence of acoustic impact on the population. The results were presented for the year of research. The results of the research indicated graphically demonstrate the advantages of the proposed solutions for reducing noise levels in a residential area
