Un hydrophone est un microphone destiné à être utilisé sous l'eau. C'est un transducteur électroacoustique, c'est-à-dire qu'il transforme, dans les liquides, des ondes acoustiques en signaux électriques.

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.

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.

With the help of a hydrophone, you can hear the splashing of water, splashes of the surf, sounds of engines and propellers of ships passing in the distance, and the noise from fish, whales, dolphins, seals and other aquatic life.

2021年10月1日 · Generally, acoustic transducers convert the acoustic pressure to electronic/optical signals and vice versa. Familiar names and accessories such as speaker and microphone which are used as the transmitter and receiver in the air are replaced by the projector and the hydrophone underwater.

"L'hydrophone marche très bien ! Parfait pour du Sound Design. J'ai enregistré des bulles et divers frottements sous l'eau ! Aussi en mer pour des animaux comme des baleines. 3m me semble largement suffisant pour une utilisation simple, 8m semble nécessaire pour les enregistrements sous-marin ! Sav très rapide et très gentil.

2023年10月13日 · A hydrophone is essentially an underwater microphone. It’s a sensor designed to pick up and record sounds underwater, converting the pressure fluctuations caused by sound waves into electrical signals that can be analyzed, recorded, and interpreted.

A hydrophone works by converting sound pressure waves in water into electrical signals. This conversion process involves a transducer, a device that converts one form of energy into another.
