I am 66 years old, I have no tinnitus issues but after a
lifetime of noise exposure in industrial work environments my hearing tests
indicate very significant hearing loss above 4k in both ears.
I have habitually used tone bypass in the past but I now crank up the treble. It helps a great deal. I have been told that hearing aids do not boost missing frequencies but instead indiscriminately simply making everything a lot louder.
In the past when using firearms or near heavy (loud) equipment I always used both ear plugs and ear muffs at the same time. Evidently those precautions were not sufficient.
