This study compares three methods of predicting the effect of dual-frequency vibration on tracking performance, given a knowledge of the separate effects of each frequency. The total rms tracking error, rms input-correlated error and rms remnant in each axis of a two dimensional, pursuit tracking task during combined 315 and 500Hz vertical, whole-body vibration, were predicted from (a) the rms sum of weighted components, (b) the most severe component alone, and (c) the arithmetic sum of weighted components. The best predictions of total rms tracking error, compared with measured levels, were with method (a) and the worst with method (c). However the results of predictions of input-correlatd error and remnant tracking error components show that considerable caution should be exercised in the application of this result.
