Human Vibration - 1/3 octave weightings according to ISO 5349

Hello,
I'm trying to apply frequency weightings according to ISO 5349 for hand-arm vibration.  I've been able to create the required 1/3 octave bands using the 1/n octave VI, but I'm having difficulty applying the required weights to those frequencies.  Has anyone had success doing this for hand-arm or whole body vibration?  I've read previous discussion threads, and could not find a solution to this common problem.  Any help would be appreciated.  I'm using 7.1.  Thanks, Jim. (jglancey@udel.edu).

The Sound and Vibration Measurement Suite now includes filters for measureing human vibration.   These filters are compliant with ISO 2631-1, ISO-8041, and ISO 5349-1.

 

The following 9 weighting filters (in time and frequency domain) are available forHuman Vibration.  These filters will support both 1 and N channels:

Wb - Weighting for vertical whole-body vibration, z-axis, seated, standing or recumbent person, based on ISO 2631-4

 

Wc - Weighting for horizontal whole-body vibration, x-axis, seat back, seated person, based on ISO 2631-1

 

Wd - Weighting for horizontal whole-body vibration, x- or y-axis, seated, standing or recumbent person, based on ISO 2631-1

 

We - Weighting for rotational whole-body vibration, all directions, seated person,

based on ISO 2631-1

 

Wf - Weighting for vertical whole-body vibration, z-axis motion sickness, seated or standing person, based on ISO 2631-1

 

Wh - Weighting for hand-arm vibration, all directions,

based on ISO 5349-1

 

Wj - Weighting for vertical head vibration, x-axis recumbent person, based on ISO 2631-1

 

Wk - Weighting for vertical whole-body vibration, z-axis seated, standing or recumbent person, based on ISO 2631-1

 

Wm - Weighting for whole-body vibration in buildings, all directions, based on ISO 2631-2
