We run our worship band on Sunday mornings at a volume between 85-100 decibels. If someone complains that it's too loud and will damage our ears, this is not true according to OSHA standards (we have a copy of them in the sound booth).
See HERE: OSHA allows 8 hours of exposure to 90 dBA but only 2 hours of exposure to 100 dBA sound levels.
So... what's really loud and dangerous to hearing? The answer is: sports events. See "Fighting Hearing Loss From the Crowd’s Roar." "Earlier this fall, Seattle Seahawks fans at CenturyLink Field broke the world record for loudest stadium crowd with a skull-splitting 136.6 decibels. That volume, as the Seahawks’ website boasts, hits the scale somewhere between “serious hearing damage” and “eardrum rupture.”
Just weeks later, Kansas City Chiefs fans at Arrowhead Stadium topped that number with 137.5 screaming decibels of their own."
