    "abstract": "We discuss some general aspects of acoustic black holes. We begin by\ndescribing the associated formalism with which acoustic black holes are\nestablished, then we show how to model arbitrary geometries by using a de Laval\nnozzle. It is argued that even though the Hawking temperature of these black\nholes is too low to be detected, acoustic black holes have interesting\nclassical properties, some of which are outlined here, that should be explored.",
