I have tinnitus in the left ear only and it is intermittant.It started after a loud Three Dog Night concert at the Biltmore Estate in Asheville,NC 3 years ago.My hearing seems normal(for age 57) and I listen to everything from classical to Allman Brothers at no higher than 70 to 75 db with some 85db excursions. The medical recommendations are to keep the SPLs below 85db and you are okay. Three Dog night was way louder from the 5th row. I had no earplugs and stuffed paper in my ears, but it didn't help. I'm sure I have some damage because of the continued tinnitus. Be careful of concerts.
