手柄、座椅和地板的振荡运动在身体中产生复杂的感觉模式，这些运动的检测取决于身体对施加振动的敏感性。本研究考察了输入位置（手、座位和脚）和振动频率（手和脚8-315Hz；座位2-315Hz）对三个轴（前后、横向和垂直）中振动感知的绝对阈值的影响。将96名20 ~ 29岁的男性分为8组，每组12人，确定感知阈值；每一组人的手、座位或脚在三个轴中的一个上都受到振动（一组人的手同时受到横向和纵向振动）。阈值的频率依赖性在三个位置的每个方向上都是明显的；频率大于80Hz的u型加速阈值轮廓表明，手、座位和脚的心理物理通道介导的高频阈值相同。在9个轴中，在8 ~ 80Hz频率范围内，座椅垂直振动的灵敏度最大，而在频率大于100Hz时，手部垂直振动的灵敏度最大。手、座位和脚感知振动的绝对阈值与现行标准中的相关频率权重不一致。
Oscillatory motions of handles, seats, and floors produce complex patterns of sensations in the body with the detection of these motions dependent on the sensitivity of the body to the applied vibration. This study examined the effect of input location (the hand, the seat, and the foot) and vibration frequency (8–315Hz at the hand and foot; 2–315Hz at the seat) on absolute thresholds for the perception of vibration in each of three axes (fore-and-aft, lateral, and vertical). Perception thresholds were determined with 96 males aged 20–29 years divided into eight groups of 12 subjects; each group received vibration at either the hand, the seat, or the foot in one of the three axes (one group experienced both lateral and vertical vibration at the hand). A frequency dependence in the thresholds was apparent for each of the three directions at each of the three locations; U-shaped acceleration threshold contours at frequencies greater than 80Hz suggest the same psychophysical channel-mediated high-frequency thresholds at the hand, the seat, and the foot. Among the nine axes, sensitivity was greatest for vertical vibration at the seat at frequencies between 8 and 80Hz, whereas sensitivity was greatest for vertical vibration at the hand at frequencies greater than 100Hz. Absolute thresholds for the perception of vibration at the hand, the seat, and the foot are not consistent with the relevant frequency weightings in current standards.
