Abstract
The comparative analysis reveals that, depending on the insect species, the Anglo-Saxon Euro-American subjects ,less familiar to the insect sounds give as stimuli, either perceived the insects sounds as “noisy” auditory stimuli, or processed them as audio visual stimuli that induce image of “natural scenery”. This group generally gave low evaluation scores to the stimuli. Meanwhile, the Japanese subjects, familiar to the insect sounds, processed these sounds as audiovisual stimuli that evoke the images of “primal scenes”, regardless of the species of the insects. This group generally gave high scores to the stimuli. The findings of this study gives new clues to the process of the formulation of keynote sounds.
