The spatial frequency is a physical quantity necessary for the formation of a texture. Onomatopoeia are used in representing the various sensory expressions such as sound, movement and texture. The purpose of this research is to clarify the relevance of texture perception by analyzing the characteristics of the spatial frequency for each onomatopoeia. We carried out an impression evaluation of 5 out of 6 onomatopoeias with 49 images of various materials. To analyze the result, we grouped together similar onomatopoeias. We performed two-dimensional Fourier transform and converted them into a spatial frequency space. We found out that people can distinguish texture from the difference of spatial frequency, and that there is a characteristic of spatial frequency for each onomatopoeia.
