Acoustic waves can be transmitted through compressible media because these have, at all points, a “mass” characteristic and a “spring” characteristic. An equivalent to the acoustic wave that can be used in mechanical engineering is the waveguide. This can be, for example, a cylindrical tube in which equally spaced pistons (= the mass) can slide. The spaces between the pistons are filled by a volume of gas (= the spring). If the tube is closed at one end and a periodic force is applied to the piston at the open end, a standing wave is generated at certain resonant frequencies.
