Development of Construction and Acoustic Measures to Protect the Residential Area from the Noise of Shopping and Entertainment Complex
Abstract: The article is devoted to the problem of providing optimal protection from noise from the point of view of acoustics and economics of equipment for heating, ventilation and air conditioning systems on the basis of acoustic calculation and selection of noise suppression systems. When evaluating and predicting the noise regime in the premises of residential buildings and when choosing the optimal complexes of construction and acoustic measures, standard methods of performing calculations and designing noise suppression systems are used. The main sources of noise of the shopping and entertainment complex «Donetsk-City – 2» are the ventilation and air conditioning systems located in the ventilation chambers No. 1–6 and on the roof of the building. Total revealed 77 noise sources. According to the technical documentation of the manufacturers, the noise characteristics of the equipment of the «Donetsk-City – 2» gas station were determined. Based on theoretical calculations, at four settlement points on the residential territory, the total sound levels exceed the standard values for the daytime by 0.9 dBA at the settlement point RT3, and at night at all settlement points from 3.6 to 9.8 dBA. In order to reduce the noise to the standard values, noise-proof design solutions (acoustic shelters and chamber silencers) have been developed for each source.
Keywords: noise, noise mode, dB, dBA, noise-proof design solutions, acoustic shelters, chamber silencer.
