The invention is a method for the nondestructive examination of a test specimen using ultrasound. Ultrasonic waves are coupled into the test specimen with ultrasonic transducers. Ultrasonic waves, which are reflected within the test specimen, are received by the ultrasonic transducers and converted into ultrasonic signals. The method determines an average noise level, to which all discrete signal information is subjected, determines volume elements assigned to each discrete signal information having a signal level with a signal-to-noise ratio R (which is referred to as an average noise level), of 6 dB≤R, determines pairs of volumes separated by a distance A which is equal to or less than a wavelength of the ultrasonic waves coupled into the test specimen. Volumes are combined into a group and the discrete signal information is evaluated, based on at least one of polarization, frequency, wave type and wave mode.
A method for nondestructive examination of a test specimen by use of ultrasound in which ultrasonic waves are coupled into the test specimen by ultrasonic transducers and ultrasonic waves are reflected within the test specimen, are received by ultrasonic transducers and are converted into ultrasonic signals with the ultrasonic signals being stored and subsequently divided into discrete signal information by time-based phase-corrected superposition ultrasonic signal data processing with each discrete signal information being assigned to a different volume within the test specimen comprising:
