Research of Acoustic Properties of Modern Building Structures

The use of acoustic methods of noise reduction in residential and non-residential areas of modern cities is a time-consuming task, which is not solved sometimes at the proper quality level. The complexity and importance of this problem lies in the quantitative determination of the magnitude of the noise emission from the sources of noise in the path of its propagation. Practical sound insulation issues are often misinterpreted without their scientifically sound analysis and practical confirmation. The article deals with the issues of elimination of errors arising from the application of one of the most common architectural and design methods of protection against noise—modern metal plastic window fillings. The complex approach to solving the “acoustic purity” of these structures is offered at the stage of their application and operation. The analysis of evaluation of acoustic properties of window fillings, the essence of which is to consider some typical errors in solving the issues of protection against external people noise, can lead to a sharp decrease in the quality and safety of modern person’s life in the premises during work or rest. It is established that a qualitative solution to the problem of security for human habitation places requires the obligatory acoustic certification of building materials, buildings, and structures made of them.
