It’s hard to recall, but probably deep purple in ~’72. There were a few other loud ones.
I’ve had tinnitus for probably 30 years. One day I noticed a low level ringing in my right ear. I usually can ignore it. My wife says it’s because I play my music too loud (I’m pretty sure that’s not it, as I rarely play it at >85 db. The doctor told me to play music to drown out the ringing . . . I win! ;-) I’m pretty sure my hearing issues resulted from equipment (power saws, lawn mowers).
The tinnitus hasn’t gotten worse, though last year I had an episode where the ringing increased so much it would wake me at night. That lasted only a couple of days, but I had my hearing checked (I have a loss in one ear for a narrow bandwidth). The ENT dr put me on a course of steroids to see if the loss could be repaired, but sadly no go. He said I’ll just have to live with it.
