underwater listening devices the navy uses sona bouys which is an active systems that is place in a pattern where suspected submarines are, they are launched out of a p3-orion or an S3-viking, also they have a system of underwater microphones called the sousis (maybe not the correct spelling) but it monitored 24/7.
Also, most ships and submarines in the Navy have passive SONAR (listen only mode) as well as active (send a sound, then listen for the return) to detect what is near them in the water. The advantage to using passive, is that if you can keep your own ship quiet enough, the other vessel may not know that they have been detected.

What method of underwater detection is short forsound navigation and ranging?
Sonar, which stands for sound navigation and ranging, is a common method used for underwater detection by sending sound waves into the water and measuring the time it takes for the waves to bounce back. It is widely used in various applications such as fishing, navigation, and military operations.
How do echo sound waves work in the process of underwater communication?
Echo sound waves are used in underwater communication by sending out a sound signal that bounces off objects in the water and returns to the sender. This allows for the detection of obstacles, navigation, and communication with other underwater devices or animals.
What is a system that uses multiple sonar devices?
A network of sonar devices is commonly used in underwater surveillance systems to provide a wide area of coverage and enhance detection capabilities. These systems can be used for various applications such as tracking underwater objects, monitoring marine life, and detecting underwater threats. By integrating data from multiple sonar devices, a more comprehensive picture of the underwater environment can be obtained.
What did the us use before sonar?
Before sonar, the US used various acoustic detection methods, such as hydrophones and listening devices, to detect underwater objects and submarines. These methods relied on the amplification and interpretation of sound waves in water. Additionally, the US Navy also used other methods like visual observation and radar for above-water detection.
Sonar equipment sends waves into deep water and measures the?
echoes that bounce back, allowing for the detection of objects underwater. This technology is commonly used in navigation, fishing, and underwater mapping.
What are underwater sound detecting systems called?
Underwater sound detecting systems are called hydrophones. These devices are used to listen to and record sounds underwater, such as those produced by marine animals or underwater activities.
Where can motion detection devices be used?
Motion detection devices can be used in a variety of locations and applications, such as home security systems, outdoor lighting, pet monitoring, smart home automation, and energy conservation systems. They are often installed in areas where detecting movement is important for security, convenience, or efficiency purposes.
What is the name for the method used to find objects that are underwater?
Sonar, which stands for "sound navigation and ranging," is the method used to find objects underwater by emitting sound waves and measuring the time it takes for them to bounce back. This allows for the detection and location of underwater objects like shipwrecks, submarines, and marine life.
What was used before sonar?
Before sonar, there were applications where individuals actually "listened to the water" with different devices. It was largely impractical for any kind of "real science" or "real military" applications, and probably was viewed as a novelty. But the first submarines were equipped with a crude (by modern standards) sonar, so the technology developed with the military need for it.
What is meant by military technology?
technology that is developed meant to be used for military purpose only. example the gps navigation devices were at one point only used by the military.
How does the military use sonar?
The military uses sonar technology for various purposes such as detecting submarines, underwater mines, and other objects in the water. Sonar systems emit sound waves that bounce off objects underwater, allowing the military to gather information on the environment and potential threats beneath the surface. Sonar is also used for navigation and communication underwater.
What devices use infrared radiation?
Devices such as remote controls, security cameras, thermal imaging cameras, and some medical devices use infrared radiation for communication, detection, or imaging. It is also used in devices like infrared saunas and night vision goggles.
