Abstract and keywords

Abstract (English):
Problems of allocation of a useful signal are considered by search of people who as a result of an emergency situation appeared in the closed volume (in blockages), against the acoustic hindrances created by environment. The simplified model of a useful signal is given. It is shown that at the solution of a problem of identification of signals from biological system for identification of nonlinear communication the good effect can give use of polyspectral characteristics of signals.

Keywords:
acoustic energy, hyperbolic symmetry, infrasonic frequencies, Fourier's spectral characteristics, Mellin's spectral characteristics, monospectral analysis, polyspectral analysis
