Abstract

Ultrasonic generators fastened to a body are used as ultrasonic probes which, on account of the inverse piezoelectric effect, are thus used for emitting ultrasound and, on account of the piezoelectric effect, are also used for detecting (ultra)sound. In the process, a plurality of ultrasonic probes are initially fastened at predetermined positions on a surface, which positions likely ensure the largest possible surface area coverage, wherein this is thereby checked regarding whether a sound event emitted by a single ultrasonic probe can be detected by at least one other ultrasonic probe. Since in each case only one ultrasonic probe is connected for emitting a sound event and the remaining ultrasonic probes are connected for receiving, in each case the position of each ultrasonic probe can be adjusted, which leads to optimised surface area coverage. Optionally, the number of provided ultrasonic probes can also be increased or reduced.
