Abstract

The aim of this research was assessing the sound and vibration exposure of user and comparing them with acceptable level of standards in ش roto-tiller Results showed that the hand and arm exposure to vibration was more than standard level and led to damages in muscles. The maximum level of vibration exposure was obtained during tilling and it was higher at the x direction than two other directions. The allowable using time of power tiller without sound isolator near the driver ear is less than 2 hours a day. This amount for those are in 7.5 meters away was according to the national standard and for those are far from the work place have no negative effect.
