If you are making A, B, or C-weighted Peak sound level measurements with noiseLAB Capture, please note that Capture does not apply these weightings to the Peak value, and always measures it with the Linear weighting, even if you have selected and A, B, or C weighting.
noiseLAB Batch applies the selected weighting to Peak, as well as to all other sound level types such as Fast, Slow and Impulse.
If you require additional information, you can contact Carsten Thomsen ct@pxi.dk .
