在存在（1）振动器发出的声音，（2）连续音调或窄带掩蔽噪声，或（3）与振动器信号同步的脉冲音调的情况下，在250和400 Hz下测定振动触觉阈值。跨模态效应的测量是在每个条件和控制条件之间发生的阈值偏移，其中耳罩消音器消除了振动器的声音。连续的音调或噪音对振动触觉阈值没有影响。然而，与振动器信号同步的听觉信号确实显著提高了振动触觉阈值。
Vibrotactile thresholds were determined at 250 and 400 Hz in the presence of (1) the sounds emitted by the vibrator, (2) continuous tonal or narrow-band masking noise, or (3) a pulsed tone synchronized with the vibrator signal. The measure of a cross-modality effect was the threshold shift occurring between each condition and the control condition, in which earmuff silencers eliminated the vibrator sounds. Continuous tones or noise had no effect upon vibrotactile thresholds. However, auditory signals synchronized with the vibrator signals did significantly elevate vibrotactile thresholds.
