I took a hearing test at a free screening today. I'm not sure how reliable it was, because frankly I was distracted by a bunch of talking and other noise outside the (not exaclty soundproof!) booth while I was trying to listen to the tones. Anyway, the results showed that my left ear was worse than my right one, with 10-dB dips at 1000Hz and 3000Hz. My right ear showed only a 5-dB dip at 1000Hz. They assured me that all this was within normal range, and I've seen audiology pages on the Web that seem to confirm it. But, geez, 10 freakin' dB? That's a lot!
If anything, my right ear should have been worse than my left, because that's the one that got hit with the ear infection some years back (leaving me with mild tinnitus in that ear). i have always been very careful not too listen too loud. Well, maybe it's congenital (which as we all know is Latin for "with genitals." .
