earplugs AND earmuffs!

seriously though, another problem too (especially at electronica/dance
concerts) is that at many venues people aren't really there for the music..
they just don't shut UP during the concerts.. so the music goes up.. people
talk louder, the music gets louder, etc. combine that with a small room
with a p.a. designed for a much bigger space.. and you have a real problem.

Another problem is general ignorance of the issue. When talking to one
person about the subject I was told that "headphones are worse," as if the
person didn't realize that its the SPL at the ear that makes the difference,
not headphones or loudspeakers.

The problem would be so easily solved.. just use a nice limiter going into
the amp to make sure that the volume levels can't get higher than say, 95dB.

I used to work in a pulp mill. The rules for ear protection were strictly
followed.. 8 hours at 85 db max, 1 hour at 95dB max, according to the
Alberta labor code. Its ironic that people who make a living using their
ears don't show the same respect for their hearing, and the hearing of
others.
