Scattering problems on rotating acoustic black holes can be studied in the time domain by using numerical methods only. In order to obtain high quality results in simulations, tools developed by numerical relativists in the case of rotating Kerr black holes must be adopted, i.e. constrained evolution schemes for strongly symmetric and non symmetric hyperbolic systems of PDEs and excision techniques in horizon penetrating coordinates. In this paper such a program is presented and analogies between astrophysical and acoustic black holes are discussed in relation with Press and Teukolsky's relativistic "black hole bomb."
