- Abstract
- This paper presents an approach allowing to reduce by up to 30–40 dB and more the low-frequency noise critically affecting human health, functional activity and comfort, as well as the instrument accuracy. This paper considers some methodological aspects and results of designing the composites with a polymer matrix and modifying fillers of inorganic and biopolymer polydisperse phase, the algorithms for predicting and analyzing the efficiency of sound insulation by the criterion of transmission loss when the waves pass through a thin single- or multilayer medium. The validity of the approach is confirmed by correctness of applied physical and chemical methods of the composites synthesis, and experimental data obtained for the models tested in the acoustic duct. The results methods of the research can be used in developing the soundproof structures for aircraft of various purposes, and in microelectronics.
