In this paper we consider the acoustic metric obtained from an Abelian Higgsmodel extended with higher derivative terms in the bosonic sector whichdescribes an acoustic rotating black hole and analyze the phenomena ofsuperresonance, analogue Aharonov-Bohm effect and absorption. We investigatethese effects by computing the scalar wave scattering by a draining bathtubvortex and discuss the physical interpretation of higher derivative terms.Furthermore, we show that the absorption does not vanish as the drainingparameter tends to zero.
