A good strategy for evaluating an alternative vibration measure such as vibration power absorption (VP A) is to compare it with weighted and unweighted acceleration values that have been applied to investigate hand-arm vibration exposures for many years. Several studies have made such comparisons, but there have been conflicting conclusions. This is primarily because different comparison methods were used in these studies. To resolve these contradictions, the first objective of this study was to identify an appropriate comparison method. As the second objective, the identified method was used to examine relationships between location-specific VP As and acceleration measures. This study found that the vibration power absorbed in the palm-wrist-arm system is reasonably correlated with ISO-weighted acceleration, but that absorbed in the fingers is highly correlated with unweighted acceleration. The implications of the findings are discussed.
