Chris,
I flew light aircraft over a period of 35 years, and I do have some
high-frequency loss, enough so that I, at times, use a hearing aid in one
ear. But, in my work during that same period I was exposed to plant noise
well over 110db, where we were told to use ear plugs and ear muffs. I
figure that my loss is much more attributable to the plant environment than
to my flying.
Don't the active noise-cancelling headsets help with your problem?
