Nondestructive ultrasound - testing method for implementation in a testing device for the detection of damage in a test area of a structural part by determination of reflections on inhomogeneities in the test region, wherein on the basis of the structure of at least one ultrasound - transmitter to the coupling of ultrasound excitations in the structural part to be tested and at least two ultrasound - receiver for reception of responses from the test area of the structural part to the ultrasound excitations are installed permanently, wherein the further in the test region a number of test points are determined and stored, in such a way that, in the testing device for each test point and each location of the ultrasound - receiver device select areas for signal shapes are implemented in the presence of a inhomogeneity in the respective test point at this is reflected and from the respective ultrasound - receiver may be measured, the ultrasound - test method comprises the steps of,– Coupling of at least one predetermined excitation in the structural part and measurement and storage of the answers from the test area of the structural part by means of each receiver,– Comparison of the of each receiver actually measured response to the expected..
