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.

Extrapolating a bit, that is one of the reasons
why an
unamplified singer in an opera theatre can have a dramatic
effect that is much stronger than someone yelling into a
microphone and being amplified to 130 dB SPL. By which I
don't want to imply that amplified music is wrong in any
sense.
*anything* at 130 dB SPL is wrong in any sense. :p
