Humans can hear from 20 Hz to 15-20 kHz dependingon age. Some bat sounds humans can hear. The squeaks andsquawks that bats make in their roosts or which occurbetween females and their pups can be detected by humanears, but these noises aren’t considered to be echolocationsounds.
Besides, can you hear bats flying?

Secondly, what is the sound of a bat? Different species of bats have distinct calls,but in general, bat sounds are described as “clicks.”When these sounds are slowed down, however, they are moresimilar to a bird’s chirp, and tend to have noticeably differenttones.
Also Know, how many Hertz can a bat hear?
“Humans can perceive sounds from 20 Hz to 20,000Hz while bats’ sensitivity ranges from less than 100 Hz to200,000 Hz (normally written as 200 kHz).”
Why can’t we hear the sound made by bats?
As we know, a bat emits ultrasonic wavesof high pitch to avoid from obstacles or for hunting their preys.Frequencies higher than 20 kHz are called ultrasonic sound.Hence, we are unable to hear the sound made bythem.

How far can a human hear?
The commonly stated range of human hearing is 20Hz to 20 kHz. Under ideal laboratory conditions, humans canhear sound as low as 12 Hz and as high as 28 kHz, though thethreshold increases sharply at 15 kHz in adults, corresponding tothe last auditory channel of the cochlea.
Can bats see in the dark?
How do bats find their way around in thedark? Many people think bats are blind, but in factthey can see almost as well as humans. However, atnight, their ears are more important than their eyes – they usea special sonar system called ‘echolocation,’ meaning they findthings using echoes.
How do humans use echolocation?
Human echolocation is the ability ofhumans to detect objects in their environment by sensingechoes from those objects, by actively creating sounds: forexample, by tapping their canes, lightly stomping their foot,snapping their fingers, or making clicking noises with theirmouths.
What animals use sonar?
Echolocating animals include some mammalsand a few birds; most notably microchiropteran bats and odontocetes(toothed whales and dolphins), but also in simpler form in othergroups such as shrews, one genus of megachiropteran bats(Rousettus) and two cave dwelling bird groups, the so-called caveswiftlets in the genus
Can a snake hear?
Snakes have no visible ear, so they don’thear sounds as we do. But it’s not quite right to say thatsnakes are deaf. They have vestiges of the apparatus forhearing inside their heads, and that setup is attached to their jawbones, so they feel vibrations very well and may hearlow-frequency airborne sounds.
How sensitive are dogs ears?
According to Coren, when sounds are between 3,000 and12,000 Hz in frequency, dogs’ ears are far moresensitive than ours. They can hear those sounds when theyare between -5 dB and -15 dB on average. That means dogs canhear sounds that are not loud enough for ourears.
