卧位人员对振动的感知阈值是与振动暴露监管有关的政府机构的一个重要指标。研究了卧位受试者对连续正弦振动、水平和垂直方向单次和多次正弦振动的感觉阈值。我们发现，作为频率的函数，垂直振动的阈值曲线具有不同于横卧位置的水平振动的特征。脉冲振动的阈值随着脉冲串的拉长而变小(更容易被察觉)，直到在S持续时间为4小时时达到饱和。脉冲持续时间大于4 S的阈值与连续振动的阈值相同。这表明，在心理声学中，振动感觉的时间整合是存在的。
The thresholds of perception of vibration by recumbent men are a significant index for the governmental agency concerned with regulation of vibration exposure. The thresholds of perception of continuous sinusoidal vibrations and single and multiple bursts of sinusoidal vibrations in the horizontal and vertical directions were investigated in recumbent men. We found that the threshold curves, as a function of the frequency, had different characteristics for vertical vibrations than for horizontal vibrations in the recumbent position. The threshold values for pulsed vibrations became smaller (easier to perceive) as the bursts were elongated until saturation occurred at 4 s duration. Threshold values for pulse durations longer than 4 s were the same as those for continuous vibration. This suggests the existence of temporal integration of sensation of vibrations as in psychoacoustics.
