In the report the mathematical bases of the theory of hydraulic shock are
given.  Empirical data of acoustic processes, which take place in the certain
situations, are assembled and analyzed.

Short Time Fourier Transform (STFT) and Continuous Wavelet Transform (CWT) of
signals, written down in characteristic points, are made in MatLab environment.

On the basis of this analysis, the work of concrete water supply system is
optimized.
