Data analysis
The collected vibration data was analyzed using the
Bruel & Kjaer PULSE LabShop 14.1 software. The
root-mean-square (rms) acceleration at one-third
octave bands in the frequency range between 6.3
and 1250 Hz for each axis was used for calculating
weighted rms accelerations (ahwx, ahwy, and ahwz).
The weighting factors according to ISO 5349-1
(2001) were applied. Frequency weighting is done
because the risk of damage to the hand is not equal
