We discuss the properties of the phonon spectrum emitted in transonic flows which mimic black hole metrics. The validity limit of the gravitational analogy proposed by Unruh will be discussed. We also discuss the black hole laser effect, and compare the predictions with the observations made by J. Steinhauer in 2014.
