Abstract
Strange sounds generated by machines are expressed by onomatopoeia. And onomatopoeia expresses trouble or poor condition of the machines. Especially, many kinds of onomatopoeia are used for expressing strange sound of automobiles, and the relationship between onomatopoeia and the sources of strange sound is reported. In this study application of onomatopoeia for expressing strange sound is discussed. In order to solve the above matter, we chose onomatopoeia, which is used well. 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 and the vocalized sounds were analyzed by using a one-third-octave analyzer. By comparing the auditory sensory test results with actual sound, we clarified that a frequency range of a sound regarded as an onomatopoeia almost corresponds to peak frequency of an actual sound. And we investigated relationship between the auditory sensory test results and the vocalized sounds, too.
