When i first started visiting venues again in 1984 after a lay off my hearing didnt get back to normal till at least mid afternoon the next day, since then i have always worn earplugs and im sure i would be deaf now if i hadnt, cant understand why more people dont use them they will regret it !!! Best ones are from Aearo Ltd Stockport still hear the music just as well but really helps when you sit next to Mace and Roger Banks
