Piezoelectric ceramic for low frequency hydrophones Yuhai's piezoelectric block has been utilized continuously in low frequency hydrophones in more than 30 years. A hydrophone (Ancient Greek ὕδωρ = water[1] and φωνή = sound[1]) is a microphone designed to be used underwater for recording or listening to underwater sound. Most hydrophones are based on a piezoelectric transducer that generates an electric potential when subjected to a pressure change, such as a sound wave.
