A lot of people express a sound by the same onomatopoeia. In order to solve the relationship between a continuous sound and the corresponding onomatopoeia, sounds were made on the basis of word information of onomatopoeia. We performed the auditory sensory tests by using the prepared sounds. Furthermore, the actual sounds were analyzed by using a one-third-octave analyzer. By comparing the auditory sensory test results with actual sound, we clarified that the frequency of the sound to hear as onomatopoeia is close to the frequency of the actual sound.
