Were you ever in a school band? I was in every band class the school offered from grade 6 thru 12 and I attribute my tinnitus to constant loud instruments every day in those enclosed spaces. Four of those years I sat directly in front of the percussion section in a tiered seating layout, where my ears were exposed to snare drum and cymbals from mere feet away. I have constant ringing in both ears... fortunately it isn’t debilitating for me. I hope awareness around ear protection continues to grow.
