Hydrophones are underwater devices that detect and record sounds from all directions in the ocean. Most hydrophones use a piezoelectric transducer to detect pressure changes caused by sound waves and convert them into electrical signals. These signals are then analyzed and recorded to monitor underwater sounds with high precision. Hydrophones are used to study marine mammal communication, ocean currents, and underwater ecosystems, as well as for underwater surveillance and seafloor mapping.
