Just looked through 1474D but could not find exact definition of what A-weighting means, or most importantly, what it does and how it affects results.
Can someone explain, or link to document explaining it?

thanks, just saw it on google search.
I see A-weight is synonymous with A contours or A filters.
For exact weightings at given frequencies see:
