โœฆ Synopsis

A variational treatment of the problem of sound transmission in narrow tubes is described as an alternative to the more usual analytical procedures, which are limited to mathematically tractable geometries. This method can be used for any cross-sectional geometry, as long as the cross-section of the tube is uniform along its length. Very simple low frequency and high frequency approximate solutions are obtained by the use of idealized trial functions, and these compare tolerably well to existing analytical solutions for a variety of geometries.

Dissipative vehicle exhaust silencers often have cross-sectional geometries that defy straightforward analytical solution of the acoustic eigenproblem; some kind of solution is, however, required as a part of the basis for computational silencer design methods. As a useful alternative to some of the

This paper deals with a semi-analytical finite element (SAFE) method for modeling wave propagation in waveguides of arbitrary cross-section. The method simply requires the finite element discretization of the cross-section of the waveguide, and assumes harmonic motion along the wave propagation dire
