The solutions for increasing the reliability of shock-acoustic control are proposed. A sensing device of new design, allowing for geometrical combining of the points of excitement and acceptance of elastic fluctuations, is developed. An installation is developed for conducting pilot studies. A software allowing attracting probable statistical techniques of mathematical processing to making decision on rejection of products is developed in LabView programming environment. The choice of the informative harmonicas of ranges of vibroacoustic tones is realized with the application of the environment of finite element modulation of ANSYS. The experimental research is conducted. The results of finite element modeling fully correspond to the experiment.
