PRODUCT DESCRIPTION

Reference Hydrophone

A Piezo hydrophone is a kind of underwater microphone designed to monitor underwater noise .  A typical piezo hydrophone works by detecting pressure changes in the surrounding environment and converting sound waves into voltage. The speed and distance of the sound wave propagating in the water is proportional to the pressure change , which will determine the nature of the electrical output transmitted.
