For the control of composite constructions of shock-acoustic method (method of free oscillations) designed and developed measuring and diagnostic system with the original software package. Package of applied programs integrated into a virtual shell that enables to reduce setup time and debugging measuring and diagnostic complex. In the analysis of signals and issue decisions "correct-reject" uses probabilistic and statistical methods of evaluation.

Keywords: Shock-acoustic method, the local method of free oscillations, composite materials, technical diagnostics, nondestructive control, fast Fourier transform, the standard, confidence intervals, range, vibroacoustic signals, LabVIEW.

Developed the method of calculating the informative harmonic of vibroacoustic signals with using finite element modeling software ANSYS. For approbation technique experimental researches were conducted.
