PSYCHOPHYSICAL RELATIONSHIPS CHARACTERIZING HUMAN RESPONSE TO WHOLE-BODY SINUSOIDAL VERTICAL VIBRATION

摘要

An experimental investigation determined that the psychophysical relationships between subjective discomfort evaluations to vibratory stimuli and subjective evaluations of the inten¬sity of vibratory stimuli can be expressed in a linear fashion. Furthermore, significant dif-ferences were found to exist between discomfort and intensity subjective responses for several but not all the discrete frequencies investigated. The implication of these results is that ride quality criteria based upon subjective evaluation of vibration intensity should be applied cau¬tiously in the development of criteria for human comfort.
