WebA hydrophone is an underwater listening device. Just as a microphone is used to detect sound in the air, a hydrophone detects sounds in the water and converts the acoustic energy into electrical energy. What is hydrophone sensitivity? Hydrophone sensitivity is the ratio of its output voltage to the sound pressure in the fluid surrounding it. … WebThe invention claimed is: 1. A hydrophone device, comprising: a) an air-backed cylinder comprising a piezoelectric ceramic material; b) a pair of end caps each disposed on a different open end of the cylinder; c) an electrode or lead extending through one of the end caps and into the cylinder; d) the electrode or lead having a shape and a lateral width …
