I live in the Austin area and it is becoming more and more common to see Mexican free tailed bats. SY, sofaspud, and others that know this area know what I'm talking about.
I've asked several friends if they can hear the bats but everyone I've asked to date says they hear nothing. I clearly hear them when I'm working in the yard at dusk. There is no sound but as they come around and fly above me, I can clearly hear them above my head and see them.
Is it common that humans can hear their unique 'chirps'?

I just googled mexican free tailed bat sounds and i could hear them on the you tube video. So they are in the audio range that we can hear. Maybe your friends need to turn their hearing aids on or up.
My friends are in their 40's! One article that I read commented that the Mexican free-tailed bat is audible when trying to avoid collision, otherwise it could be 40 kHz or higher.
Good to know I don't have special bat hearing or maybe that I've been gifted golden ears finally! 😀

I forget the exact bat species that's common round where I live, but I do know I can hear them when they have to go round me when I'm walking in the lanes in the early evenings.
The clicks are about as loud as a Bull Finch when taking avoiding action and not very fast in timing - their 'hunting noise' is a very quiet high pitched squeal.
Am 43 and can hear 16k tone
When I stand still for 5mins while the group does a few circuits, they know exactly where I am an will fly within inches of me.......
Then the local Barn Owl shows up and the shows over.
