An investigation of the effect of vibration duration on the evaluation of subjective responses to horizontal vibration

A laboratory experiment was conducted to investigate an evaluation method for building habitability based on subjective responses to vibrations caused by external sources. Twenty-five individuals participated in the experiment, which involved 76 input stimulus conditions, including vibrations based on field records and sinusoidal vibrations in the horizontal direction. Subjective responses were measured in terms of “magnitude,” “concern,” and “discomfort,” The study compared several domestic and international evaluation methods for environmental vibrations with subjective responses, revealing that the vibration dose value, which accounts for the effect of vibration duration raised to the fourth power, was the most reasonable method.
