Abstract: Inhomogeneous fluid flows which become supersonic are known to produceacoustic analogs of ergoregions and horizons. This leads to Hawking-likeradiation of phonons with a temperature essentially given by the gradient ofthe velocity at the horizon. We find such acoustic dumb holes in chargedconformal fluids and use the fluid-gravity correspondence to construct dualgravity solutions. A class of quasinormal modes around these gravitationalbackgrounds perceive a horizon. Upon quantization, this implies a thermalspectrum for these modes.
