Description
In this work we invstigate the possibility of the acoustic analogue of a
phenomenon like superradiance, that is, the amplification of a sound wave by
reflection from the ergo-region of a rotating acoustic black hole in the
fluid "draining bathtub" model in the presence of a desclination be
amplified or reduced in agreement with the value of the deficit angle.
