There is no cure for Tinitus!
My father is totally deaf and was an expert marksman. (representing RI in the Camp Perry meet in the early 50’s) We spend a lot of time shooting (outside) with a 30-06 when I was a youngun. Back in the 70’s there was no priority to safety and I didn’t wear protection. Now I have tinitus and always will.
I wear ear plugs of the highest rating as well as ear muffs also.
Always protect your hearing, if you can.
I wear plugs and muffs now... was just a plug man... but six months ago I damaged my left ear when a plug came out as I fired a .45 acp. I have high frequency Tinitus in my left ear. Be warned!
