Abstract
In article the technique of studying of an interference of wave packages and introduction of notion of temporary coherence is described. It assumes carrying out educational experiment with acoustic wave packages and use of the computer model allowing to receive the graph of dependence of resultant intensity in a observer point from a path difference for wave packages of various length. All this proves that when imposing packages of waves the interference occurs if the path difference doesn't exceed length of wave packages, and allows to prove notion of temporary coherence.
