To help them find their prey in the dark, most bat species have developed a remarkable navigation system called echolocation. To understand how echolocation works, imagine an "echo canyon." If you stand on the edge of a canyon and shout "hello," you'll hear your own voice coming back to you an instant later. The process that makes this happen is pretty simple. You produced sound by rushing air from your lungs past your vibrating vocal chords. These vibrations caused fluctuations in the rushing air, which formed a sound wave. A sound wave is just a moving pattern of fluctuations in air pressure. The changing air pressure pushes surrounding air particles out and then pulls them back in. These particles then push and pull the particles next to them, passing on the energy and pattern of the sound. In this way, sound can travel long distances through the air. The pitch and tone of the sound are determined by the frequency of the air-pressure fluctuations, which is determined by the way you move your vocal chords. When you shout, you produce a sound wave that travels across the canyon. The rock face on the opposite side of the canyon deflects the air-pressure energy of the sound wave so that it begins moving in the opposite direction, heading back to you. In an area where atmospheric air pressure and air composition is constant, sound waves always move at the same speed. If you knew the speed of sound in the area, and you had a very precise stopwatch, you could use sound to determine the distance across the canyon.

Which animals use supersonic waves and how?
None ! Some animals such as bats, use ultra-sonic sound to locate prey, and 'see' in the dark.
What is a method used by some animals bats for example that uses sound waves to help locate prey and other objects in the dark?
Echo
The bats can fly in the dark because?
They produce ultrasonic waves.
Do vampire bats have sonar?
No. SONAR (SOund Navigation And Ranging) is an acronym for a human technology that used for underwater navigation. Bats have the ability that may be similar to SONAR, but they do not use a machine and do not use it under water. They use their ultra sensitive hearing and brain processing to "see" in the dark with sound waves, sort of like how we see with light waves.
How does a bat use ultra sound?
Bats use ultra sound by sending out ultra sound waves and then when the bounce back the know exactly where everything is even in the dark. I will work better with ultra sound because all of the wave will bounce back otherwise some of the wave will be absorbed.
What sound do bats make?
bats make high pitched squeals to find their way around in the dark, they have poor eyesight so the noises bounce back to tell them where things are.
Are bats the only mammals that can see in the dark?
no Many mammals can see in the dark far better than humans, but bats actually don't "see" in the dark at all. They make a high pitched screeching sound that bounces off the ground, trees, cliff faces, prey and any other object. They hear it and their brains can calculate what their surroundings are like based on how long it took for the sound waves to come back.
How do bats use sound to help them see?
Bats use sound to help see in the dark (don't forget bats are blind) by using something called echolocation. echolocation is were the bats make noises and the noise waves bounce back giving the bat an idea of its surrounding.However when the bat finds prey its sound changes. The sound the bat makes when getting pray is a clicking sound which gets faster and faster as it gets closer.Echolocation is like that of a submarine's radar.Another animal which uses this exact same method is the dolphin.
Did sound waves travel in dark?
For propagation of sound only a material medium is enough and not light. So it could travel thorugh darkness
What is ultrasound waves?
Is cyclic sound pressure with a frequency greater than the upper limit of human hearing. Ultrasound imaging is a common diagnostic medical procedure that uses high-frequency sound waves to produce dynamic images (sonograms) of organs, tissues, or blood flow inside the body.
Can bats see it the dark?
no actually they send waves and ear where they bounce off then they know somthing is near
Which birds uses echoes to fly safely in the dark?
Only bats do this. They make a high-piched squeak. The sound waves from the noise; if they are "bounced" of a object and heard again by the bat, the bat then knows that there is an object there and can thus avoid it.
