- Abstract
- This paper presents an approach to a qualitative change, by 12 to 17 dB and more, of the low-frequency sound absorption inside and outside the transport vehicles. In the approach, the problems are solved of designing the composites of polymer matrixes with inorganic and biopolymer polydisperse phases, and of modeling, measuring and analyzing the sound-absorbing properties of thin mono-/bilayer structural elements based on the new composites. Validity of the approach is confirmed by correctness of the physical, chemical and measurement methods used, and by the results of experimental studying the test-models of the composites. These research results can be used in the current developing and prospective designing the aircraft for various purposes, and other types of transport vehicles.
