An Integrated Approach to Performing Acoustic Calculations during Technical Inspection of Emergency Housing Stock

The sound insulation of enclosure structure is one of the important factors affecting the living comfort. The article discusses the method for conducting acoustic calculations in the investigation n apartment building. According to the results of a technical survey, the building was declared emergency. A large number of defects were recorded that negatively affect the acoustic properties of the building envelope. For the walls of the building, airborne noise insulation indices were determined, which are standardized parameters of sound insulation of enclosing structures. The index was calculated as an acoustically flat structure with a solid section, taking into account the surface density. For intermediate floors, the impact noise index was determined by calculation. Conclusions are given on the results of the acoustic calculations, the features of such calculations during the technical inspection of emergency housing stock, as well as the influence of existing defects on the sound insulation capacity of the enclosing structures are reflected.
