Reports and documents which deal with human response and evaluation to shipboard vibration exposure are summarised. The purpose of this explanations is to make clear the present situation of researches and international standardization of this field. In Chapter 1, characteristics of human body to vibration exposure are explained. Human response to vibration exposure can be evaluated as ergonomics on the analogy of the relation between the dose(input) and its effect (output) in the human body. Between the input and the output, there are perception and evaluation of individual scale. Here the evaluation of individual scale is affected by many factors as noise, temperature, atmosphere etc. An example of the effects of noise on the exposure limit of vibration is shown. Then the experimental method to evaluate human exposure to shipboard vibration, and examples of analytical spring-dashpot-model of human body for x axis (back to chest), y axis (right to left side) and z axis (foot to head) are explained. In Chapter 2, individual, national and international standards (including proposals) of vibration evaluation are explained in order to make clear the interrelation among them. Here the vibration, as the object of evaluation, is devided into three categories. The first is single frequency vibration lowerer than 1 Hz, the second is single frequency vibration from 1 Hz to 80 Hz and the last is multi-frequency or multi-axes vibration. For the evaluation of multi-frequency vibration, experimental results and analysis of them conducted by authors are presented. At last, many factors surrounding the evaluation of human exposure to ship board vibration are presented.
