Finite Amplitude Effects in Rectangular Cavities with Perturbed Boundaries.
Abstract
The effects of boundary perturbations on finite-amplitude acoustical standing waves in rectangular, rigid-walled cavities were investigated using non-linear theory. When a high amplitude standing wave of frequency omega is generated in a cavity, non-linear effects will cause a stimulation of certain normal modes whose resonance frequencies are integer multiples of omega. There could be excitation of other normal modes, not belonging to the family of the driven mode. The purpose of this research was to investigate the possibility that deviations from the idealized geometry could account for these observations.
