Abstract:
Knowing how emotions change with sound pressure is the present concern with a synthesized acoustical display of this poem. Emotional changes in the poem are felt like the music of Beethoven. The sound pressure alone cannot express the delicate nuances of the emotion; other elements are needed for the whole emotional expression. But the sound pressure is the basic medium by which emotion is communicated; when one is emotionally excited, one often raises his voice. So, in the epic, strong sound pressure is assumed to be an expression of strong emotion. Hence, it occurred to the author to represent the emotional changes in terms of those of sound pressure. It is clear that each book has its idiosyncratic pattern of change of sound pressure; hence, emotion is inseparably related to the contents. Most interestingly, the fall of Eve and Adam appears in Book IX with two changes of abnormally high increase of sound pressure to about 80 dB against the average 73 dB. The change of emotion can be heard with a sine-wave generator using techniques developed by the author.
