Spinning Music Decible Levels, Tinnitus

[mimitabby]

But when I measured the levels in her class, it was "only" 86-87 dB - truly painful for me, but well below OSHA regulation for a one-hour class.

ONLY???
ow, i agree!

and perhaps an authority figure (like the spin instructor) needs to tell these people what for?
THey sound pretty childish, mocking people for being sensible!
