A shame a musician of his caliber to lose any hearing. I have tinnitus, but no lose of hearing in any ear as yet at 74. I can still hear the sizzle of a high-hat (I’m a drummer) and all lower frequencies. Although I’ve been in bands much of my life and currently listen to my CD’s at high volume, my hearing is better than my wife’s who is years younger. Weird.
Have you tried that treatment on Reddit for tinnitus?
Place the palms of your hands over your ears with fingers resting gently on the back of your head. Your middle fingers should point toward one another just above the base of your skull. Place your index fingers on top of you middle fingers and snap them (the index fingers) onto the skull making a loud, drumming noise. Repeat 40-50 times. Some people experience immediate relief with this method. Repeat several times a day for as long as necessary to reduce tinnitus.Dr. Jan Strydom, of A2Z of Health, Beauty and Fintess.org.
The drummer afflicts others, not themselves. Worse, they play as loud as they want which forces the other musicians to turn up the amps and then suffer.
