Hi DRK,
thanks for posting again. A few things:
1) In the same user manual on pages 9-9 and 9-10 there's this info:
Performing Third-Octave Analysis Outside the Audio Range
You might need to perform third-octave analysis on signals outside of the
20 Hz–20 kHz range. For example, you might need to evaluate human
exposure to whole body vibration with potential signals of interest in
the 0.5 Hz–80 Hz range. To perform third-octave analysis outside the
20 Hz–20 kHz range, use either the SVT Fractional-octave Analysis
[ANSI] VI or the SVT Fractional-octave Analysis [IEC] VI and select a
bandwidth equal to 1/3 octave, as illustrated in Figure 9-7.
2)We don't have a weighting filter according to that standard currently but we would like to discuss the standard a little more with you, if possible. Can you give us a phone number (preferably) or an email address that we can contact you at?
Thanks!
Brian Spears
