Abstract

Different methods of determining cumulative vibration dose using the alternative frequency weightings are investigated and compared to the development sensorineural and vascular hand-arm vibration (HAV) injury. The comparison is based on a large historical database of measured HAV spectra from a wide range industrial machines, and a database of exposure history and injury from subjects attending the Health and Safety Laboratory's (HSL) referral center. Acceleration spectra from the HSL HAV database were analyzed to give weighted values for each of the alternative frequency weightings. HSL's Hand Arm Vibration Syndrome (HAVS) referral center collects data on diagnosis of HAVS and the history of symptoms. Increasing prevalence for any form of HAVS with percentile suggests a useful dose measure. Lower Bayesian Information Criterion (BIC) values suggest stronger dose measures, differences between BIC values of less than two suggest weak evidence for favoring one relationship above another, differences greater than 10 suggest very strong evidence.
