The tactile perception of surface roughness can be modulated by sounds. Our previous study demonstrated that white noise altered the tactile perception of the roughness of abrasive paper having a specific particle size. In the present study, we investigated whether the congruity between tactile and auditory information could be a critical factor in influencing the tactile perception of roughness. The results revealed that when the information about roughness in the modalities was congruent, the sound modulated the tactile perception of roughness more saliently. The direction of roughness modulation depended on the sound intensity: loud sound increased the perceived tactile roughness, whereas soft sound decreased it.
