During haptic exploration of surfaces, complex mechanical oscillations-of surface displacement and air pressure-are generated, which are then transduced by receptors in the skin and in the inner ear. Tactile and auditory signals thus convey redundant information about texture, partially carried in the spectral content of these signals. It is no surprise, then, that the representation of temporal frequency is linked in the auditory and somatosensory systems. An emergent hypothesis is that there exists a supramodal representation of temporal frequency, and by extension texture.
在对表面进行触觉探索时，会产生复杂的机械振动——表面位移和气压的振动，然后这些振动由皮肤和内耳中的感受器进行转换。触觉和听觉信号因此传达了关于纹理的冗余信息，部分信息包含在这些信号的频谱内容中。那么，时间频率的表征在听觉和体感系统中相互关联也就不足为奇了。一个新出现的假说是，存在一种时间频率的超模态表征，进而也存在纹理的超模态表征。
