Abstract
The proposed approach based on the inverse iteration method is intended to study
eigenforms and frequencies of the acoustic gas oscillations in regions of complex spatial
form using the geometrical immersion method on each iteration. It permits us to reduce the
problem of acoustic oscillations in three dimensional domain to a converging sequence of
problems in the canonical domain involving the initial one.
The approach has been developed to solve the problem on spectral gas properties in a
chamber, taking into account stationary flows and acoustic conductivity of the region
boundaries.
The numerical results, obtained for a tube with the cross-section
