Their wing-beats are just audible if you are close enough in quiet surroundings.
I have experienced this - it's a lovely soft, velvety whisper.
Young people with their ears in full health may be able to hear some bats' navigation and social calls, as rapid, very faint clicks, again in close proximity in quite surroundings. I have done myself - when I was about 20.
Generally though the call frequencies render the squeaks and chirps themselvesultrasonic - far above the human ear's frequency range.
Deepnding on species the hunting call chirps can range from about 50kHz to well over 100kHz, and at very high rates. They chirp because that gives much mroe accurate discrimination of prey from background than would be given by a single-pitch "cheep".
The sound pressure level of bat in full cryis extraordinarily high considering the tiny size of the animal's vocal tract, although the amount of energy in it is obviously very low: some bats can call at over 120dB re 20µPa that is the Threshold of Hearing for humans; and many can exceed 100dB.
What else can I help you with?
Can bats hear higher pitched noises than humans?
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.
Why is it that humans hear noises better when the noises are in front of them?
That depends on the directionality of our pinna (ear cup) which is front localisation.

Is it true that dogs can hear better than humans?
Yes, it's true. They can hear noises from a mile away.
Can bats hear noises?
Exceptionally well. And contrary to popular belief, bats aren't blind, either.
Can animals hear sounds that humans can't hear?
yes, animals hear thousands of high pitched noises that we cant hear at all. hope this helps :)
Can mice hear humans and distinguish their sounds from other noises?
Yes, mice can hear humans and distinguish their sounds from other noises. Mice have a keen sense of hearing and can detect a wide range of frequencies, allowing them to differentiate between different sounds, including those made by humans.
Do all animals see the same frequencies of visible light as humans do Do all animals hear the same frequencies of sound as humans do?
no bats and many marine animals can hear high frequency noises We can't. Most other animals can't
The lowest frequency that humans can hear is approximatel?
The lowest frequency that humans can hear is generally around 20 Hz. This can vary from person to person due to age, genetics, and exposure to loud noises.
What can you hear in Paraguay?
You will hear most noises you hear anywhere else mixed with unique Paraguayan indigenous noises
What is the approximate range frequencies that humans can hear?
Humans can generally hear sound frequencies between 20 Hz and 20,000 Hz. This range may vary depending on factors such as age and exposure to loud noises.
