I went for an Everglades air boat ride in the mid-1960s.
Sat right next to the motor exhaust pipe.
I was a teenager and did not want people to think I was a wimp by covering my ears.
Bad decision - been listening to two high pitched whistling sounds 24-7-365 ever since.
Yes, it doesn’t take much. Been around lots of gunfire, etc. my whole life by had several episodes of heavy gunfire in enclosed spaces in my early 20’s of which my rifle and others near me were fired near my head and my ears have never been the same since. No hearing protection being worn obviously. One of the events caused me nearly lose all hearing in my right ear. I need hearing aids but don’t want them. My wife begs me to get them. I have to watch TV with subtitles. I’m 44. Lol
