Predicting discomfort from whole-body vertical …
Within each of these five postures, 12 subjects judged the discomfort caused by vertical sinusoidal whole-body vibration (at frequencies from 1 to 20 Hz at magnitudes from 0.2 to 2.0 ms-2 r.m.s.) relative to the discomfort produced by a reference vibration (8 Hz at 0.4 ms-2 r.m.s.). With 8-Hz vertical vibration, the subjects also judged ...
