Scientific paper

We investigate the phonon radiation from a spherically symmetrical,
stationary, viscid-free son-ic black hole by using a semi-classical method. The
backreaction of the radiated phonon is taken into account. We obtain the phonon
emission temperature, and it is consistent with the Hawking's formula.
