周波数変調音の擬音語表現とサイン音としての機能イメージ

抄録

To obtain basic data for designing easy to understand and memorize auditory signals, we examined the functionary imagery and onomatopoeic representations associated with periodic frequency-modulated (FM) tones. When the modulation wave was rectangular and the modulation rate was slower than 5Hz, FM tones were associated with the imagery of alarm and were represented by repeatedly prolonged syllables. When the modulation rate was 15 to 30Hz, FM tones evoked the functional imagery of calling and the onomatopoeic representation of repeated flapping. These results showed that the functional imagery and onomatopoeic representation of FM tones varied as a function of modulation rate.
