Claim 12:
13. An arrangement for carrying out the claimed method of claim 1, the arrangement comprising a device for detecting signals based on defects in a test specimen, the device comprising:
at least one transmitting transducer;
at least a first receiving transducer and at least one second receiving transducer, wherein the transmitting transducer and the at least one first receiving transducer and the at least one second receiving transducer are arranged at a distance from one another and in a manner inclined towards one another with their acoustic axes such that through-transmission signals form a V-shape between the at least one transmitting transducer and the at least one first receiving transducer;
said evaluation unit for evaluating the signals recorded by the device;
wherein the at least one transmitting transducer, the at least one first receiving transducer, and the at least one second receiving transducer are arranged in a receptacle,
wherein the receptacle is movable in the direction of the test specimen and the receptacle has a guide element which is brought into contact with the test specimen in such a way that when the guide element makes contact with the test specimen, the transmitting transducer, the at least one first receiving transducer and the at least one second receiving transducer are arranged at a distance from the test specimen in the receptacle;
wherein the device has a plurality of pairings of transmitting transducers, and first receiving transducers, and second receiving transducers arranged offset with respect to one another transversely with respect to the feed direction and one behind another in the feed direction in a common receptacle.
