I have been hypersensitive to loud noise and certain frequencies (like a whistle....AGONY!!) I also work in a loud bar, by the end of the night I feel awful!! I started wearing a "snow bunny" out fit so I could wear earmuffs. Then, someone told me to try the earplugs for swimmers that are like a clear putty that I can put over top of my ear. I can't put earplugs in my ears, it hurts too much. I hope this helps and am interested in any other solutions.
