A hydrophone (Ancient Greek: ὕδωρ + φωνή, lit. 'water + sound') is a microphone designed for underwater use, for recording or listening to underwater sound. Most hydrophones contains a piezoelectric transducer that generates an electric potential when subjected to a pressure change, such as a sound wave.

Hydrophones and accessories for recording, playback, and live underwater sound.

2024年6月16日 · A hydrophone is an underwater device that detects and records ocean sounds from all directions. People often think that the underwater world is silent. In fact, numerous marine organisms use sound for communication, reproduction, and to seek prey.

Whether within an array or as a single element, the hydrophone is the basic sensor of underwater acoustics. Currently, several technologies are available for acoustic exploration of the ocean. For decades, the U.S. Navy has used a device called a sonobuoy to record the sound of …

the SQ26-H1 is the most compact underwater recording system that exists. System includes a hydrophone, a digital recorder, and some accessories. Records sounds up to 40kHz which is twice as high as humans with perfect hearing can detect
