I used to be able to hear bats, up till I was about 40.
I think there are some that make lower frequency chirps, I could not hear everything. But it was enough to know when they were around and then I could look at roughly where they were, so it was real.
I was sad when I lost that, and gained tinnitus, but then the bats don't seem to be around much any more.
Very good night vision, could drive as easily at night as in the day.
Also now compromised by macular degeneration, which is unlucky as I am quite young for it. Lutein and zeaxanthin tablets (extract from marigolds, a plant I like) should help stop it getting worse I hope.
Do you have anything that is good, rather than just a nuisance or problem?
