The subject of acoustic waves might easily be considered a mature one, quite
specialized, with narrow and circumscribed fields of interest and of application. The
present book is an evidence of the opposite: it witnesses how the concept of acoustic
wave, a collective displacement of matter which perturbs an equilibrium
configuration, is a pervasive concept, which emerges in very different fields. This type
of phenomena can be analyzed from different points of view, it can be exploited in
different ways, and is the object of active investigations.
