He's a better man than I; years ago I got a call from my friend who was yelling that there was a bat in her house, got it trapped under a bowl but was freaking out. So I came over and it was a fucking moth the size of a bat. Then I freaked out and just threw the bowl out the window as far as I could. I owe that girl one bowl and may I be reincarnated into a moth for what I did :(
In person they really o sound a lot like a dial up modem (but higher frequencies). I could definitely see them making your throat tingle, I've mate that happen before (usually it's more the back of the neck and base of the skull though) with really aggressive high pass filtering.
If it's cold outside, it will die without food. Once bats wake up in the winter it's feed or die, and their hibernation is pretty sensitive. For this reason, don't go in caves in the winter if they have bats.
