Time dependency of whole-body vibration discomfort

Time dependency of whole-body vibration discomfort

The current International Standard (ISO 2631, 1978) on whole-body vibration defines a complex relation between discomfort arid duration of vibration exposure. There are doubts concerning the accuracy of this relation and there are difficulties and dangers in its application to some non-steady-state conditions. This paper compares the ISO time-dependency with those based on root mean square (rms) and root mean quad (rmq) averaging of levels over time. [The rmq averaging procedure is based on experimental studies reported by Griffin and Whitham (1980) J. Acoust. Soc. Am. 68, 1277-1284.] It is shown that although the rmq procedure was developed from studies involving only short duration vibration, it defines a time dependency which may be acceptable for much longer periods.

Abstract

The current International Standard (ISO 2631, 1978) on whole-body vibration defines a complex relation between discomfort arid duration of vibration exposure. There are doubts concerning the accuracy of this relation and there are difficulties and dangers in its application to some non-steady-state conditions. This paper compares the ISO time-dependency with those based on root mean square (rms) and root mean quad (rmq) averaging of levels over time. [The rmq averaging procedure is based on experimental studies reported by Griffin and Whitham (1980) J. Acoust. Soc. Am. 68, 1277-1284.] It is shown that although the rmq procedure was developed from studies involving only short duration vibration, it defines a time dependency which may be acceptable for much longer periods.
