Abstract

We propose an experimental model using the Laval nozzle of a sonic analogue of the Hawking radiation. We observe a power spectrum of the out-going wave emitted from the vicinity a sonic horizon in place of a created particle number. Our treatment is based on classical theory, and it will make experiments to be easier. This experimental possibility is a great advantage of our model.
