Abstract

The analytical methods for computation of sound insulation of multi-layer cylindrical constructions are formulated in the paper. The relationship between multi-layer and one-layer constructions is specified. With the use of analytical methods described in the paper, sound insulation of one-layer and multi-layer constructions was computed.
The results obtained showed that sound insulation of a one-layer construction of the same thickness was by two orders less in comparison with the sound insulation of multi-layer construction.
