Before you go off and compare that to a TL reading or whatnot, remember that OSHA and other orgs use weighted measurements, usually "A" weighted measurements.

So the two aren't directly comparable.

Yup.

The lower the frequency, the less damaging it is to the ears...

[CBFryman2 5,000+ posts]

noah, that wasnt your highest score was it?

if so im louder with my ava on term lab than you where with your XXX on term lab. 144.9 on freshly calibrated audiocontroll before the sub had a chance to fully get broken in, 145.0 exactly on term lab at some shop down in orlando with my new box, 28Hz tuning. Never threw my 40Hz plug in on any mic.
