  We explore the possibility of the acoustic analogue of a super-radiance like
phenomenon, i.e., 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 the pressure be amplified or reduced in agreement with
the value of the parameter $\left(\gamma=1+ \frac{kn\rho_0^{n-1}
}{c^2}\right)$. We remark that the interval of frequencies depend upon the
neo-newtonian parameter $\gamma$\, ($\bar{\Omega}_H = \frac{2
}{1+\gamma}\;\Omega_{H}$)\textbf{ and becomes narrow in this work}. As a
consequence, the tuning of the neo-newtonian parameter $\left(\gamma=1+
\frac{kn\rho_0^{n-1} }{c^2}\right)$ changes the rate of loss of the acoustic
black hole mass.
