  1. SPL Meters | Mic's | Calibration | Sound Cards
    I'm looking at the Cal file for the Galaxy 140 and they go like this: 5.0 -21.89 5.6 -19.60 6.3 -18.48 7.1 -17.22 8.0 -15.87 9.0 -14.59 ... 80.0 -0.75 90.0 -0.53 100.0 -0.35 Does that mean the meter reads low and I need to *ADD* 21.89db at 5hz? Just want to clarify.
