Linear
: General calculation formula with harmonic values without squaring.
Square
: General calculation formula with squared harmonics
Psophometry up to 50th harmonic can be mapped using the type
square
and the
normalization
Hn
.
Since ibaPDA supports only one weighting factor per harmonic, the factors have
to be multiplied first for psophometry and specified as total weighting factor per
harmonic.
Normalization:
Hn/H1
: All harmonics are normalized to the value of the fundamental frequency,
i.e. divided by this value. This corresponds to the relative values in ibaPDA, how-
ever without the factor 100 for percent.
Hn/RMS
: All harmonics are normalized to the RMS value, i.e. divided by the RMS
value
Hn
: absolute value of the harmonics
Limit profiles
With this option you can predefine a limit profile for the harmonics or the interhar-
monics. This profile can be displayed in the Spectrum view. In addition, the prede-
fined limits are saved as additional information in order to facilitate a later analysis.
You will find further information how to configure additional profiles in the chapter
