This paper introduces the brief guidelines on general aspects of tests and experiments with human subjects. Detailed methods for measuring whole-body vibration are reviewed for those tests and experiments and compared each other. Such comparison is found to be very useful in choosing adequate methods for human related tests and experiments. Of course, it is also expected to be very meaningful to our automotive research and industrial fields that are critical to the ride quality of their products with uncomfortable acoustic noise and vibration.

This paper reviews recent international standards related to human-related vibration and compares them to KS standards. This comparison and analysis reveals that the current direction and activity in ISO is in progress and presents logical ways of updating Korean standards in the future. Finally, the current activity of upgrading Korean standards in the Korean TC 108/SC 4 is introduced.

This paper addresses issues encountered in using the ISO and national standard codes to assess the hazards of whole-body vibration and repeat shocks. Their assessment methods are given in ISO 2631-1 (1974, 1985, 1997) and BS 6841 (1987) that are now available to us. Two standard codes can yield unfortunately different assessment results even for a single measured vibration signal. Possible reasons for such different results are pointed out and, furthermore, related questions that should be re-examined in the future are raised in this paper.

This paper introduces new approaches attempted to evaluate quantitatively the effects of repeated shocks exposed to human. This attempt, by the members of ISO TC 108 / CS4, has been made to add a standardised draft of ISO 2631 Part 1 which covers newly the human response to repeated shocks. It contains the review of previous work related to shocks responses to human and suggests a mathematical model to predict the three-axis lumbar spine accelerations from the measured seat accelerations. The predicted accelerations are used to evaluate the vibration dose to the spine. The evaluated dose values are shown to enable the assessment of adverse health effects.

The recent national contract (Ecotechnopia 21) supported by the ministry of environment puts much significance on new issues for the assessment of human effects arising from vibration and noise exposed to human. This paper focuses only on hand-arm vibration since it has been a major problem in protecting vibration exposure to human. To set up a systematic way of assessing adverse effects of hand-arm vibration, surveys were made on recent international standards and researches related to hand-arm vibration. The measurement and evaluation methods of hand-arm transmitted vibration, the relationship between vibration exposure and effects on health, and the assessment methods of nerve dysfunctions are addressed in this paper. Those methods are linked into a logical way of assessing effects of hand-arm vibration on human. Finally, the current activities and achievements in this work are briefly summarised.
