Same here, I blew a hole in my left eardrum about 30 years ago and it rings all the time. I think being around and shooting 155mm guns did the most damage. Telling direction of sound is close to impossible. I bought one of those hearing enhancement earmuffs and it helps a lot, but just isn't the same as normal hearing. I make sure my grandsons have earplugs or muffs on especially when target shooting.
