Measurement and evaluation of whole-body vibration at work

The vibration to which the human body can be exposed while at work is complex. It may be composed of various frequencies, occur in several directions and contact the body at more than one point. The vibration will often vary from moment to moment and may contain shocks. The useful evaluation of vibration with respect to human response requires that the manner in which the responses depend on the frequency, direction duration of the vibration and the occurrence of shocks is adequately taken into account. This paper describes current methods of measuring and evaluating human exposures to whole-body vibration and shock.
