Human Vibration Weighting Curves as specified in the ISO standards

[bhoward]

I need to use the Wk and Wd weigthing curves used in human vibration analysis as specified in ISO 2631. Weigting curves are provide in the sound and vibration tool box for sound (ie A,B,C weighting) how do I find or create the Wk and Wd curves?

 Thanks in advance.

Hello bhoward,

Unfortunately, the Sounds and Vibration toolkit does not support Wd and Wk weighting curves. The standards that the toolkit does support are ANSI and IEC.

Sound and Vibration Measurement Suite 6.0 now includes human vibration filters compliant with ISO 2631-1, ISO-8041, and ISO 5349-1.  

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

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

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

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

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

based on ISO 2631-1

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

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

based on ISO 5349-1

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

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

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