Not sure what is more the cause of my slight ringing and hearing loss in my ears since I was in my early 20’s, hunting(rifles and shotguns) in the 80’s I didn’t ever wear plugs, Harley straight pipes, or Iron Maiden, Black Sabbath, and Metallica, it’s pretty much a toss up. 30 years later I wear electronic ear muffs, have at least pipes that reduce the decibels on bikes, and tore up a napkin and stuck it in my ears at a Iron Maiden show 6 years ago. One of the ranges I go to sometimes I’m the only one there so once in a blue moon I will forget to have my ears on, unpleasant but it hasn’t made anything worse.
