Bats use echolocation to sense movement and their surroundings. We cannot hear the high pitched noise they emit because it is of a higher frequency than the human ear can register. There are some sounds of a bat that we can hear, but the sounds that we can't hear is because the squeaks are so high that you really need ultrasound to hear it.
The same way we do - by using their ears ! Bats use ultra-sonic sound which is higher than the range humans can hear - their 'squeaks' bounce off objects, and prey and are reflected back to the bat so it can navigate in total darkness.
Depending on age, humans can hear between 20 Hz and 15-20 kHz. Bat calls have a frequency range of 9 kHz to 200 kHz.So Yes.

Bats use sound by sending a sound wave to the object or prey that is going to approch,the sound wave bonces of of the prey and goes back to the bat. The sound wave that goes back to the bat tells the bat how far away the bat is and how fast it is approching the bat.
well bats have a very good sound detecting system because they can hear their prey or predators approaching better, as a matter of fact i know you have heard the phrase used 'i'm as blind as a bat', well it turns out bats have very good seeing too!!
Bats cannot see, so they use sound that humans can't hear to receive signals about what is in front of them.

Not unless you're a bat

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

Can you show me what sound bats make and yes they do make a sound.
bats can hear sounds of higher frequency than humans (supersonic) because they produce them and these sound waves echo back to them by bouncing of items so that they can see how far something is. Just like in submarines. therfore they need to 'hear' these 'supersonic' waves to see.
The bat. It can "hear" sound waves produced by it's own voice. The shape of the waves change when they bounce off obstacles, so the bat literally navigates by it's ears.
Light travels faster (much faster) than sound.
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.
The short \a\ sound is "ah" as opposed to the long \a\ where you hear the sound of the letter. Examples: fat act jam gas bad pad had bat cap dad cat
