Abstract (en)
[origin: EP1890140A1] The method involves creating an ultrasonic surface wave by one test head (30). The ultrasonic surface wave is received by another test head (32). Acoustic properties are determined within the structural conditions on the basis of the relation between a created and received ultrasonic surface wave. The degree of damages of the interior structural conditions is determined on the basis of the acoustic properties ascertained.
