Abstract: The article is devoted to the issues of noise protection of outdoor units of ventilation and air conditioning systems in the territory adjacent to the office building. When working, standard methods of performing calculations and designing noise reduction systems are used. The main sources of noise in an office building are the external units of the ventilation, air heating and air conditioning system located on the facade and covering of the building. In total, 12 external noise sources were identified, located on the facade (S3, S4), the coating of the building (S1, S2, S5-S12). According to the technical documentation of the manufacturers, the noise characteristics of the office building equipment are determined. Based on theoretical calculations, at three points in the residential area, the total sound levels exceed the standard values for daytime from 9,1 to 12,5 dBA. In order to reduce noise to standard values, noise-proof design solutions for acoustic shelters have been developed for each source.
Keywords: noise, noise mode, noise-proof design solutions, acoustic shelters, dB, dBA.
