This is a blackboard pedagogical lecture aimed at students. The analogy between light propagation in a curved geometry and sound propagation in moving media can be exploited to 'create' acoustic black hole geometries. This analogy has been found extremely useful to address from a new point of view unsolved questions concerning the role of ultra-high frequencies at the origin of Hawking radiation.
