Rotational superradiance is one of the most fascinating phenomena inblack-hole physics. Here, with the aim of probing quantum properties ofsuperradiance in the lab, we investigate the interaction of the acoustic waveswith quantum vortices in Bose-Einstein condensates (BEC) in the framework ofdissipative mean-field model. We find the conditions of the acoustic-inducedquantum phase slips in condensates with ring topology and discuss thepossibility of observing an acoustic analogue of quantum superradiance inultracold atomic gases.
