绝对振动触觉阈值测定超过中指的远端垫和鱼际隆起的右手的5个S。使用25和700 Hz之间的八个频率和0.0008和1.3 cm 2之间的七个接触器尺寸进行测量。当绘制为频率的函数时，在具有0.005-cm 2接触器的指垫处测量的阈值曲线是U形的，在250 Hz的区域中具有最大灵敏度。当作为接触器尺寸的函数绘制时，阈值以每增加一倍面积3 dB的速率降低。
Absolute vibrotactile thresholds were determined over the distal pad of the middle finger and thenar eminence of the right hands of five Ss. Measurements were made using eight frequencies between 25 and 700 Hz and seven contactor sizes between .0008 and 1.3 cm2. When plotted as a function of frequency, the threshold curve measured at the fingerpad with a .005-cm2 contactor is U shaped, with a maximum sensitivity in the region of 250 Hz. When plotted as a function of contactor size, the threshold decreases at a rate of 3 dB per doubling of the area.
