I'm curious: when you talk about your high frequency hearing loss, did you mean it was already gone 30 years ago, or that now your hearing tops out at 15k? If it tops out at 15k now, and if you are middle aged, that's quite good.
I'm almost 55 and mine tops out just under 15k. Which frankly surprises me, especially given having played in very loud bands earlier in life and working in production sound for 30 years.
There's various on-line "how old is your hearing" tests and I come up with a "hearing age" of between 38 and 40 years old, so not doing too badly at almost 55. But I believe I'm now at the crest in age where hearing starts taking a bigger dive in the high frequencies...so I better get as much listening in while I can enjoy those sparkling highs, while I can!
But, I've been protecting my hearing for a long time. I started noticing Tinnitus in the early 90's and that put the fear-of-gawd in me, so I started protecting my hearing from then on. Many of the guys I played with in bands who didn't protect their hearing are now having some pretty serious hearing issues! Like waking up one morning and all their high frequency is gone!
