warehouse: For talks and general listening it should be at an average of 68db. For singing and such, you should be at a max of 85db. Typically the amps at the cong. level should hit the protect limit at 100db or so.
I know you're just being sarcastic, but when I worked sound at the Circuit Assemblies and District Conventions in SoCal we would actually use a dB meter to help calibrate our sound systems.
That was the TECHNICAL/OBJECTIVE means of measuring. But we knew we had the volume "just right" when we got equal amounts of complaints that the sound was too loud/not loud enough! ... lol
BTW, your dB settings seem a little on the high side to me.
