I don't have specs handy, but certainly enough to cause tinnitis! A 
few years back we had an audiologist give our chapter a talk. The 
audiologist gave a local tech a measuring device to carry along with 
him through his day of tuning. The audiologist concluded that a day's 
tuning can certainly be within the "harmful" range. He recommended 
ear plugs/muffs/filters & thought it foolish if we didn't use ETDs 
for most of the grunt work.
