High-frequency (1000-2000 Hz) sinusoidal vibrations of the skin, which are normally imperceptible, induce distinct sensations when amplitude modulation is applied in the frequency region around 200 Hz. This phenomenon appears to be initiated in the mechanoreceptor, as a result of rectification in the mechanoelectrical transduction process. The curve for sensitivity to modulation frequency resembles the frequency-sensitivity curve of the Pacini receptor system. The low-frequency slope is flatter than that of comparable psychophysical frequency-threshold curves for sinusoidal stimuli. This finding suggests that mechanical filtering (in the capsule of the Pacinian corpuscle and the surrounding skin tissue) contributes to the detection threshold. The characteristics of such a mechanical filter are estimated.
通常难以察觉的皮肤高频（1000 - 2000赫兹）正弦振动，当在200赫兹左右的频率区域施加幅度调制时会引发明显的感觉。这种现象似乎是在机械感受器中启动的，是机电转换过程中整流的结果。调制频率敏感度曲线类似于帕西尼受体系统的频率敏感度曲线。低频斜率比正弦刺激的可比心理物理频率阈值曲线更平缓。这一发现表明，（在帕西尼小体的囊和周围皮肤组织中）机械滤波有助于检测阈值。估计了这种机械滤波器的特性。
