I didn't realize I had it until fairly recently, when I noticed that the high frequencies from my stereo seemed very muted. My system was fairly old (20+ years), and I first assumed that the equipment was finally starting to give out. I have played drums for 20+ years, and never noticed any loss of HF detail while playing - presumably because of the 100dB+ levels - so I didn't think my ears could be the culprit. LOL.
So I replaced everything - speakers, electronics, cables, interconnects.....everything. To my (semi)horror, I discovered that the sound was still muted, although the new system does indeed have better detail than the old one. So, apparently I have some high-frequency hearing loss.......and then I noticed the low level but insistent high pitched squealing in both ears. Ah, good fortune. Hearing loss and Tinnitus.
