Ultrasound head e.g. for testing materials for cracks, has sound signals summated as useful signal for coupling into or received from medium

An ultrasound head for coupling ultrasound waves into a medium has a flat piezo-element (1), on either side of which are arranged ultrasound radiating surfaces (2a,2b) for radiating sound signals (5a,5b) which can be diverted by an ultrasound reflector (6a,6b) so that the sound signals of the first...
