I went to a lot of drag races and back then, wearing hearing protection was felt to be a "girly thing". I somehow made it through those years and still had good hearing, but that started to change after the ear infection from hell I had about 25 years ago. I hadn't had one for like 15+ years. I went to the "Urgent Care" in town and the doctor gave me a script for an antibiotic. It got worse, much worse. Went to see my family doctor, who shook his head and said, "He gave you the wrong antibiotic for an ear infection!". Great. It was pretty bad at that point, it hurt like hell, and my hearing in my right ear was pretty much gone. I got the new meds, and they took the steam out of the infection, but as soon as those pills were gone, the infection came roaring back, and the left ear joined in. I had stuff coming out of both ears and ended up at an ENT and he said I had one of the worst infections he had seen in a very long time. A shot of some insanely expensive antibiotic and two different ones in pill form finally got rid of it. My hearing in both ears came back fine, and he was shocked that I could still hear 20KHZ with my right ear, and the left wasn't as good, but it was still better than the average 40 year old man.
But the infection scarred my eustation tube on my right ear, and as time went by, I had to "pop" my ear more and more often, or I lost all my high end hearing. Along with that, I had Cicada sounding buzzing, which started on NY day. I woke up hearing "them" and wondered what was going on. Later I added whistles and hissing. Not loud enough to really bother me, my having to constantly pop my ears was the main hassle. Finally, it got to the point where popping them only lasted about a minute or so, so I finally went to the ENT, a different office, and after testing, "You have a very odd hearing loss!", and I had a choice of living with it, getting a tube put into my eardrum, or getting a hearing aid. I ended up getting the tube, and the only positive is my tinnitus was much reduced, the Cicadas are totally gone, the whistles are few and the hiss is now almost hard to hear. Along with the Cicadas being gone, so is most of my hearing. The tube will be falling out soon, and I don't know what I'm going to do.
