虽然许多研究致力于确定人体对全身振动的反应的等效舒适度曲线，但很少考虑引起这种舒适度曲线的感觉的来源。本文表明，对于垂直振动，在不同频率下，身体不适的位置有明显的差异，并且位置受振动水平的影响不大。对于水平运动，无论振动频率或方向如何，下腹部和臀部的不适感都占主导地位。语义缩放技术表明，在4至16 Hz范围内的垂直振动加速度的最大灵敏度，但对于前后和横向振动，随着频率的增加，灵敏度降低2Hz以上。
Although much research has been devoted to the determination of equivalent comfort contours for human response to whole-body vibration little consideration has been given to the source of the feelings that give rise to such comfort contours. This paper shows that for vertical vibration there is a distinct difference in the locations of discomfort on the body at different frequencies and that the locations are not much affected by the vibration level. For horizontal motions, feelings of discomfort predominated in the lower abdomen and buttocks irrespective of vibration frequency or direction. A semantic scaling technique indicates the maximum sensitivity to vertical vibration acceleration in the 4 to 16 Hz range, but for both fore-and aft and lateral vibration there is a decrease in sensitivity with increasing frequency above 2Hz.
