Abstract
The article presents a method which considers the influence of fuel and oxidizer tanks of a launch vehicle on sound propagation in the inter-tank space. An example of finding resonant acoustic modes and frequencies of a launch vehicle module and the analysis of sound-insulation characteristics of the module are also given.
