In addition to the time-weighting filters, the ISO standards present a series of specific indicators to evaluate the affect of vibrations on the Human body. The following section will present you how to use the toolkit to access these indicators.

As defined in the table, <math>A_w</math>, <math>A(8)</math>, Peak amplitude and Crest factor indicators can be obtained in NVGate via post-processing of the appropriate weighted signal. The other indicators will be calculated by the toolkit.
