Before I got my hearingaid the jazz club I frequented used to ask my advice when doing the sound check- if I found it too loud they would turn it down!
Now I'm glad I can sometimes turn my aid down (or off) when I go to noisy gigs. The "party" setting that tunes out noise from behind is useful in theatres etc when the folks in the row behind keep yakking!
