Nondissipative Lumped Elements

  • Steven L. Garrett
Part of the Graduate Texts in Physics book series (GTP)


The goal of the chapter is to start applying the Laws of Hydrodynamics that were provided in Eqs. ( 7.32), ( 7.42), and ( 7.43). By applying these laws to some simple acoustical networks, we can begin to develop our understanding of their meaning and their broad utility in acoustics. We start by ignoring dissipation and by choosing acoustical elements that are small compared to the wavelength of sound. In this nondissipative lumped element approximation, the Continuity Equation ( 7.32) leads us to the definition of an acoustical compliance , C, that plays the same role as a capacitor in alternating current (ac) electrical circuit theory or a spring in the theory of mechanical vibrations.
