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