A method for the non-destructive testing of a test specimen by means of ultrasound and a corresponding device, the method including insonification of directed ultrasonic pulses into the test specimen 100 at an insonification angle &bgr;, wherein the insonification angle &bgr; is adjusted electronically, a. recording echo signals that result from the ultrasonic pulses insonified into the test specimen 100, b. calculation of an ERS value of a flaw 102 in the volume of the test specimen from echo signals that can be assigned to the flaw 102 for a plurality of insonification angles &bgr;, and c. generation of a graphic representation of the flaw 102, from which the dependence of the calculated ERS values of the flaw on the insonification value &bgr; can be read off at least qualitatively.
