Rezumat:

This paper establishes the experimental observations of the correspondence between the characteristics of piezoceramic materials and the sensitivity of narrow-band frequency hydrophones. The hydrophones realized in the laboratory are of narrow bandwidth with high sensitivity. They can be successfully utilized in marine communication (voice communication between divers or data transmission) because they are like selective filters for the ultrasonic frequencies.
