检测振动触觉测试刺激的阈值漂移被确定为掩蔽物强度的函数。掩蔽刺激，以275赫兹为中心的窄带噪声，以及测试刺激，15，50，80，或300赫兹的正弦脉冲，应用于手大鱼际隆起的同一部位。掩膜的强度在0到52dBSL的范围内变化。这些结果支持这样的假设，即振动触觉刺激的检测是由至少两个不相互掩蔽的受体系统介导的。
Threshold shifts for the detection of vibrotactile test stimuli were determined as a function of the intensity of a masker. The masking stimulus, narrow‐band noise centered at 275 Hz, and the test stimulus, a 15‐, 50‐, 80‐, or 300‐Hz sinusoidal burst, were applied to the same site on the thenar eminence of the hand. The intensity of the masker was varied over a range of 0 to 52 dB SL. The results support the hypothesis that the detection of vibrotactile stimuli is mediated by at least two receptor systems which do not mask each other.
