Cross-modality matching (CMM) were used for the evaluation of combined effects of sinusoidal whole-body vibration (WBV) in Z-axis with the frequencies 3-7 Hz, 1.5 ms-2, and two noise levels (L1 = 65 dBA; L2 = 85 dBA). CMM's were tested by means of three responses: handgrip force, length, estimation and brightness adjustment. The subjects were instructed to set different modalities to a value corresponding to their perception of vibration. The combination of WBV and L2 caused higher sensation responses than WBV and L1.
采用跨模态匹配（CMM）来评估频率为3 - 7Hz、加速度为1.5m/s²的Z轴正弦全身振动（WBV）与两种噪声水平（L1 = 65 dBA；L2 = 85 dBA）的综合效果。通过三种反应对手握力、长度估计和亮度调节进行跨模态匹配测试。受试者被要求将不同模态设置为与他们对振动的感知相对应的值。与WBV和L1相比，WBV和L2的组合引起了更高的感觉反应。
