Standard Frequency Weighting

ANSI standard A, B and C weighting curves can be applied to the spectral data and/or to the total power value. The total power setting affects the values shown in the total power utility and on the total power bar along the right side of the spectrum plot if enabled. Flat is equivalent to no weighting at all. Weighting functions emphasize frequencies in the 500 to 10,000 Hz range, which is the area of greatest sensitivity to the human ear.
