Predicting vehicle ride comfort [PDF]

The Journal of the Acoustical Society of America, 1981
Laboratory experiments have shown that the discomfort caused by whole-body vibration is highly dependent on the frequency, direction and duration of the vibration, the occurrence of impulses, and on the locations of the points of contact of the body with vibrating surfaces. The acceptability of vibration in vehicles depends on situational factors which
