Apparatus for determining the acoustic intensity of focussing electroacoustic transducers

摘要

The aim is for the acoustic power emitted by the shock wave transducer (2) and the sound pressure determined hereby to be controlled or regulated in the focus (3) in order to be able to ensure optimum and efficient application of the shock waves and high-power sound pulses. For this purpose, the sound waves (6) emitted by the transducer (2) are deflected at least partially in the direction towards the transducer (2), the electric voltage induced at the transducer (2) by the reflected sound waves serving as a measure of the emitted acoustic power.
