Modeling and Estimation of Acoustic Pulse Energy Dissipation in a Waveguide with Elastic Walls

EasyChair Preprint no. 3548, version 2

Abstract

In this paper we study the wave processes in the boundary acoustic layers of the multimode waveguide systems. Wave propagation in a waveguide with "imperfectly" rigid walls is considered. Thermoacoustic effects that occur when a wave propagates in a near-surface layer with a finite impedance of the internal surface of the waveguide are considered. The estimation of the change in the energy dissipation of the propagating wave in the approximation of "imperfectly" rigid walls is performed.

Keyphrases: acoustic wave, energy dissipation, waveguide systems
