Whoa. Back up. Any noise above 85 db can do damage. In the Navy they
told us that highs did the damage but I can't find any medical support
for that.

If you're in doubt, spend the 50 bucks for a sound power meter (Radio
Shack has them), set it to the "C" scale (which has nothing to do with
the musical note "C"--sound power meters generally have two scales, "C"
that is roughly flat with a roll-off below 100 Hz and above 3 KHz, and
"A" that rolls off both ways from around 2 KHz), and if it shows over
85 then do something about it.
