Glossary

Underwater acoustic transducers can contain both transmitters and receivers, or they can be solely transmitters used in conjunction with a hydrophone. They sense reflected sound and use distance and directional data for communication, mapping and navigation.

Underwater acoustic transducers have an operational range, but are usually designed to operate at their resonance frequency to maximize output power. They are most typically single frequency transmitters, but they may contain multiple transmitters and receivers for different frequencies.
