My personal limit is about 120.  If its loud enough to hurt, it is hurting, 
and I have gotten up and left many a night club because the music was too 
loud.  I wore out the first 3 rifle barrels at the target range before one 
could buy decent ear muffs, and most of whats on the market today don't have 
the protection required.  I consider 30db a minimum.

So now, 45 years later I have what are called Carhart Notches in my 
hearing, 120 db deep at 4 khz.  I blew the hearing tester away when she was 
checking me a while back, she was at full scale with the test tone at 4 khz 
but all I could hear was the circuits white noise.  Which I heard quite 
easily.
