Of course, a lot depends on where you're measuring in relation to the speakers, and whether you're indoors or out.
We have the "freedom" to mix to just about any level we wish - as long as it meets local noise ordinances - and what your congregation and praise minister want.
Lots of regulating bodies have tables for noise exposure - OSHA, NIOSH, World Health Org, etc. Also these figures are for adults - "Children" have a much lower table (depending on who you ask)
Of course the EU has much better defined limits and are more strictly enforced (as I understand it)
God bless you if you can figure it out.
BTW, yesterday was my first outdoor festival of the year - and of course, my first noise complaint. <85 dBA mid plaza - from one of the vendors snarkily telling the organizer "my hearing is in tact". Theramin player playing along with a CD of Patsy Cline. Played two whole songs. Gonna be a long Summer.
