6.3 PERCEPTION OF AND DISCOMFORT FROM VIBRATION
The human body detects vibration through a variety of sensory systems including
those in the vestibular (balance) organs, through several types of nerve endings in the
skin, and through proprioception via soft tissues (Grifn, 1990). Each of these sys-
tems is more sensitive to some frequencies of vibration than to others. An integrated
sensation of the environment will also be enhanced through other channels such as
visual and auditory feedback, and this can make it difcult to accurately determine
the relative disturbances felt from each sy
