STUDY ABOUT EVALUATION OF HUMAN EXPOSURE TO HAND-TRANSMITTED VIBRATION
Journal Title: Journal of Science And Arts - Year 2010, Vol 13, Issue 2
Abstract
This study investigates the perception of vibrations at the fingertip of the human hand. The study involved 10 adult male subjects, constant-velocity sinusoidal excitations at different discrete frequencies in the range of 16–315 Hz, covering the frequency range of three mechanoreceptors, the Merkel and Meissner receptors and the Pacini corpuscles, in the human hand. The results of the study suggest that the vibration energy absorption into the fingers is considerably less than that into the hand at low frequencies (16-25 Hz). The finger vibration energy absorption at high frequencies (100-315 Hz) is practically independent of the hand-handle coupling condition. The finger vibration energy absorption results suggest that the ISO standardized frequency weighting (ISO 5349-1/2001) may underestimate the effect of high frequency vibration on vibration-induced finger disorders.
