Underwater Listening Devices
Underwater Listening Devices are instruments used to detect and analyze sounds in the underwater environment. These devices are used for various purposes such as marine mammal monitoring, underwater communication, navigation, and surveillance. They can be passive or active, and can operate at different frequencies and depths depending on the intended use. Passive devices are used to detect and record sounds without emitting any signal, while active devices emit a signal and analyze the returning echoes. Underwater Listening Devices are essential tools for marine biologists, oceanographers, and naval forces to study and monitor the underwater environment.
