Hydrophones

Hydrophones are specialized microphones designed to detect sound underwater. They convert sound waves—such as those made by marine animals, vessels, or geological activity—into electrical signals, allowing researchers to study underwater acoustics. Hydrophones are used in various fields, including marine biology, oceanography, and underwater surveillance. By capturing these sounds, scientists can learn about ocean ecosystems, monitor environmental changes, and even locate underwater objects. Their sensitivity to sound enables a deeper understanding of life and processes beneath the surface of the water.
