One of the approaches to an estimation of vibrations decay at nondestructive testing by a method of free vibrations is considered. The approach on the basis of robust estimation of vibrations decay is suggested. The estimation of decay parameters is being done using integral signal and at separate frequencies. The technique of robust estimation of vibrations decay parameters is presented. Examples of practical application of the developed technique are shown. The concept of an initial peak spectrum is introduced.
