This review summarizes some aspects of the theory of the Anderson localization of acoustic waves. Particular emphasis is placed on the so-called self-consistent diagrammatic approach to localization although some other theoretical methods are also briefly discussed. We also emphasize the advantage of using classical waves to study pure Anderson localization as compared to conventional electronic systems. In classical wave systems, effects analogous to electron-electron interactions in electronic systems can be carefully controlled experimentally. Another advantage of classical wave systems is that the disorder causing localization can be varied to a much greater extent and, as a consequence, there are a number of interesting resonance phenomena in classical wave localization which are not accessible in electronic systems. The possibility of using acoustic systems with flow to study the crossover between universality classes in Anderson localization is also reviewed. Here we also compare theoretical predictions with available experimental results. Detailed theoretical predictions for proposed experiments are also discussed.
