Bats use sonar to sense their surroundings. Sonar works by the bat making a high-pitched call and listening to the echo from nearby objects. So bats definitely do make a noise when they fly. Also, a bat's wings are not designed for stealth, so even if you do not recognise a bat's sonar call, then you would hear the wings beating when a bat flies close to you. In reality, nobody really thinks about the noise of bat's wings because of the noisy call.
It is unlikely that you will hear bat vocalizations because their chirps have a higher pitch than humans can hear i.e., greater than 20,000 Hz. You might hear their wings flapping.
Listen to the link below to hear what the (probably pitch-shifted) vocalizations of Mexican Free-tailed bats sound like.
bat sound like a high pitch screeching. <<cheers!!!>> >.<
FART or BURP
because they need to catch prey
*Fludder Fludder*
The use sound to detect what is around them. The echolocation sound bounces off objects and then back to the bat.
u will be surprised to know that bats do not use their eyes when they fly in darkness. A bat makes a sound continuously while it flies. The sound waves strike the nearby objects
Echolocation is a type of radar bats use to fly blind. The bats send out pulses of super sonic sound and navigate by the speed of the pulses return from what they bounced ( echoed ) off.
bats use echolocation. that means that they make high piched sound waves that humans cant hear, which bounce of objects around them, telling the bat what is around it so it can fly without bumping into anything
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.
radar
Echolocation is when you use sound to locate where something is. Bats use it.
Well bats use echo waves. These waves help them to know where everything is because bats are blind. See if you where standing there he would know your there with Eco waves with out actually seeing you
sound navigation
coz they can.
It help it survive by sensing every sound around it. Bats use hearing and echolocation to locate objects and tell their way around. Without its hearing, it would not be able to detect its surroundings.
Bats are nocturnal animals, which means they are active during the night and sleep during the day. They also tend to live in very dark places. Because they usually fly in the dark, sight would not help them much (because you can't see without light). Echolocation can be used without light, so bats use it to help them fly inplaces where they can't see.
