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. Onomatopoeia is language which people utter. Therefore it is necessary to clarify the relationship between the frequencies perceived to sound like the onomatopoeic word and uttered sounds. In this report, we paid attention to both the vowel and the consonant of uttered sound of onomatopoeia. As a result we found that the utterance time of a consonant changes by the mechanism of utterance. And the ratio of energy between the vowel and the consonant influences frequency of the sound that an onomatopoeia expresses.
