The feeling of vibration that gives rise to judgements of vibration discomfort can be predicted using evaluation procedures that take account of human sensitivity to different magnitudes, frequencies, directions, and durations of vibration. Such evaluation methods can assist vehicle optimisation via dynamic modelling before the production of prototypes and the testing and optimisation of prototypes. The measurement and evaluation of vibration will always provide imperfect predictions of discomfort when discomfort is influenced by factors other than the motion that is being measured and evaluated. This can arise when factors such as noise or seating discomfort influence judgements even when they are not noticed by those judging the vibration. Vibration evaluations may detect changes that are not detectable subjectively, because smaller changes can be detected by measurement and evaluation than by subjective assessment. Opportunities are identified to improve current standardised methods of predicting vibration discomfort from increased understanding of human sensitivity to variations in the magnitudes, frequencies, directions, and durations of vibration in transport, and the interactions between responses to vibration and other stimuli. As the methods of predicting discomfort are seen to provide useful guidance, greater unification of the methods of measuring, evaluating, and assessing human responses to vibration in the different forms of transport can be expected.
