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.
