ISO/TC 108 took up this problem, and its WG7 has prepared the document N36 "Guide for the evaluation of human exposure to whole body vibration". However, there still remain a few problems to be solved before its practical application, so it would be impossible to apply it directly to the evaluation of ship vibration. Therefore, we carried out some full-scale measurements according to the methods provided by ISO, in order to make clear the relation between human sensibility and ship vibration magnitude.
