the sonar technicians are trained to listen to the white noise from the hydrophones and pick out the sounds of propellers from other ships or subs, biological noise, basically anything in the water. from their sonar equipment they can find out what direction it is coming from and track its movements. sonar contacts are organized with a sierra designation.
under duress, subs can use active sonar. this is the classic ping. a warbling noise is emitted from the sub which carries and bounces off whatever we need to find a way to understand how to make sound with no objects, like how bats find their prey. the problem with active sonar is that everyone knows where the sub is when they use it, subs use echoes to see if there are any sort of objects in the sea and if it jumps back to the sub they have found and object.
What else can I help you with?
Why do submarines use reflection of sound waves?
For eating ;)
How sumbarines use ultrasound?
Submarines use the ultra sound in sonar in order to find any hurdles in their path as visibility is very less under water.
How are bats dolphins and submarines similar?
All use sound navigation / echo-ranging for navigation.
How do submarines target underwater objects?
They use Sonar to send sound waves to the bottom of the oceans.
Why do submarines use echolocation?
Submarines use echolocation to detect, locate, and avoid obstacles underwater, as well as to navigate their surroundings. By emitting sound waves and analyzing the echoes that bounce off objects, submarines can map their environment in conditions where visual navigation is limited or impossible.
What is the use of sonar?
SOund Navigation And Ranging = SONAR Sound is used underwater to bounce off objects. The reflections back can be measured (by electronics) to find our where they are and how far away. Used by submarines, to navigate round obstacles underwater and detect other vessels.
Do submarines use oxygen tanks?
Submarines typically use air tanks. Oxygen is very dangerous and very flammable. It's use is very limited on submarines for that reason.
Do submarines use ultrasound?
For tactical use, no. The frequencies are too high to be used for anything tactical. They are often used as part of machines for cleaning mechanical parts aboard ship though. Submarines use sonar (sound navigation and ranging), in much the same way that airplanes use radar (radio detection and ranging).
Why is water a good medium for communication between dolphins?
Sound waves travel very well in water. Warships, including submarines, use passive sonar to listen for enemy ships and submarines. Passive sonar employes underwater hydrophones to listen for sounds. They can detect sounds of ships and submarines miles away. Marine mamals such as whales and dolphins detect sound in much the same way.
