One of the earliest applications of a waveguide is the speaking tube, which was used on ships. Propagation in some waveguides leads to dispersion, a phenomenon in which the phase velocity depends on the frequency. Dispersion of elastic and sound waves in solids and liquids has been observed and treated in the scientific literature for a long time (Worzel and Ewing 1948; Pekeris 1948; Ewing et al. 1957). However, in the sub-audible acoustic domain, usually referred to as infrasound (frequencies below 20 Hz), dispersion was recognized...
